    \title Text Markup

    The text formatting commands indicate how text is to be rendered.

    \target a-command
    \section1 \\a (parameter marker)

    The \\a command tells QDoc the next word is a formal parameter name.

    A warning is emitted when a formal parameter is not documented or
    is misspelled, so when you document a function you should mention
    each formal parameter by name in the function description,
    preceded by the \\a command. The parameter name is then rendered
    in italics.

    \code
      / *!
         Constructs a line edit containing the text
         \a contents. The \a parent parameter is sent
         to the QWidget constructor.
      * /

      QLineEdit::QLineEdit(const QString &contents, QWidget *parent) :QWidget(parent)
      {
         ...
      }

    \endcode

    QDoc renders this as:

    \quotation
        \b {QLineEdit::QLineEdit ( const QString &
        contents, QWidget *parent )}

        Constructs a line edit containing the text \a contents.
        The \a parent parameter is sent to the QWidget constructor.
    \endquotation

    The formal parameter name may be enclosed between curly brackets,
    but that isn't required.

    \target c-command
    \section1 \\c (code font)

    The \\c command is used for rendering variable names, user-defined
    class names, and C++ keywords (for example, \c int and \c for) in the code
    font.

    The command renders its argument using a monospace font. For
    example:

    \code
      / *!
        The \c AnalogClock class provides a clock widget with hour
        and minute hands that is automatically updated every
        few seconds.
      * /
    \endcode

    QDoc renders this as:

    \quotation
        The \c AnalogClock class provides a clock widget with hour
        and minute hands, which are automatically updated every
        few seconds.
    \endquotation

    If the text to be rendered in the code font contains spaces, enclose the
    entire text in curly brackets.

    \code
      \c {QLineEdit::QLineEdit(const QString &contents, QWidget *parent) :QWidget(parent)}
    \endcode

    QDoc renders this as:

    \quotation
      \c {QLineEdit::QLineEdit(const QString &contents, QWidget *parent) :QWidget(parent)}
    \endquotation

    The \\c command accepts the special character \c \ within its
    argument, which renders it as a normal character. So if you want
    to use nested commands, you must use the \l {tt-command} {teletype
    (\\tt)} command instead.

    See also \l {tt-command} {\\tt} and \l {code-command} {\\code}.

    \target div-command
    \section1 \\div

    The \\div and \\enddiv commands delimit a large or small block of
    text (which may include other QDoc commands) to which special
    formatting attributes should be applied.

    An argument must be provided in curly braces, as in the qdoc
    comment shown below. The argument is not interpreted but is used
    as attribute(s) of the tag that is output by qdoc.

    For example, we might want to render an inline image so that it
    floats to the right of the current block of text:

    \code
      / *!
         \div {class="float-right"}
           \inlineimage qml-column.png
         \enddiv

      * /
    \endcode

    If qdoc is generating HTML, it will translate these commands to:

    \code
      <div class="float-right"><p><img src="images/qml-column.png" /></p></div>
    \endcode

    For HTML, the attribute value \e {float-right} then will refer to
    a clause in the style.css file, which in this case could be:

    \code
       div.float-right
       {
          float: right; margin-left: 2em
       }
    \endcode

    If qdoc is generating DITA XML, it will translate the commands to:

    \code
        <sectiondiv outputclass="float-right">
            <p>
                <fig>
                    <image href="images/qml-column.png" placement="inline"/>
                </fig>
            </p>
        </sectiondiv>
    \endcode

    Your DITA XML publishing program must then recognize the \e
    {outputclass} attribute value.

    \note Note that the \b {\\div} command can be nested.

    Below you can find an example taken from the index.qdoc file used to
    generate index.html for Qt 4.7:

    \code
        \div {class="indexbox guide"}
            \div {class="heading"}
                Qt Developer Guide
        \enddiv
            \div {class="indexboxcont indexboxbar"}
                \div {class="section indexIcon"} \emptyspan
                \enddiv
                \div {class="section"}
                    Qt is a cross-platform application and UI
                    framework. Using Qt, you can write web-enabled
                    applications once and deploy them across desktop,
                    mobile and embedded operating systems without
                    rewriting the source code.
                \enddiv
                \div {class="section sectionlist"}
                    \list
                       \li \l{Getting Started}
                       \li \l{Installation} {Installation}
                       \li \l{how-to-learn-qt.html} {How to learn Qt}
                       \li \l{tutorials.html} {Tutorials}
                       \li \l{Qt Examples} {Examples}
                       \li \l{qt4-7-intro.html} {What's new in Qt 4.7}
                    \endlist
                \enddiv
            \enddiv
        \enddiv
    \endcode

    When all the class attribute values are defined as they are in the
    style.css file that is used for rendering the Qt documentation,
    the above example is rendered as:

          \div {class="indexbox guide"}
            \div {class="heading"}
              Qt Developer Guide
        \enddiv
            \div {class="indexboxcont indexboxbar"}
              \div {class="section indexIcon"} \emptyspan
              \enddiv
              \div {class="section"}
                Qt is a cross-platform application and UI
                framework. Using Qt, you can write web-enabled
                applications once and deploy them across desktop,
                mobile and embedded operating systems without
                rewriting the source code.
              \enddiv
              \div {class="section sectionlist"}
                \list
                  \li Getting Started
                  \li Installation
                  \li How to learn Qt
                  \li Tutorials
                  \li Examples
                  \li What's new in Qt 4.7
                \endlist
             \enddiv
            \enddiv
          \enddiv

    When generating DITA XML, qdoc outputs the nested \e {div} commands as:

    \code
      <sectiondiv outputclass="indexbox guide">
          <sectiondiv outputclass="heading">
              <p>Qt Developer Guide</p>
          </sectiondiv>
          <sectiondiv outputclass="indexboxcont indexboxbar">
              <sectiondiv outputclass="section indexIcon"/>
              <sectiondiv outputclass="section">

    \endcode

    Your DITA XML publishing program must recognize the values of the
    \e {outputclass} attribute.

    See also \l {span-command} {\\span}.

    \target span-command
    \section1 \\span

    The \\span command applies special formatting to a small block of text.

    Two arguments must be provided, each argument in curly braces, as
    shown in the QDoc comment below. The first argument is not
    interpreted, but specifies the formatting attribute(s) of the tag
    output by QDoc. The second argument is the text to be rendered with
    the special formatting attributes.

    For example, we might want to render the first word of each
    element in a numeric list in blue.

    \code
        / *!
            Global variables with complex types:
        \list 1
                \li \span {class="variableName"} {mutableComplex1} in globals.cpp at line 14
                \li \span {class="variableName"} {mutableComplex2} in globals.cpp at line 15
                \li \span {class="variableName"} {constComplex1} in globals.cpp at line 16
                \li \span {class="variableName"} {constComplex2} in globals.cpp at line 17
            \endlist
        * /
    \endcode

    Class \e {variableName} refers to a clause in your style.css.

    \code
        .variableName
        {
            font-family: courier;
        color: blue
        }
    \endcode

    Using the \e {variableName} clause shown above, the example is rendered as:

    Global variables with complex types:
    \list 1
        \li \span {class="variableName"} {mutableComplex1} in globals.cpp at line 14
        \li \span {class="variableName"} {mutableComplex2} in globals.cpp at line 15
        \li \span {class="variableName"} {constComplex1} in globals.cpp at line 16
        \li \span {class="variableName"} {constComplex2} in globals.cpp at line 17
    \endlist

    \note The \b span command does not cause a new paragraph to be
    started.

    See also \l {div-command} {\\div}.

    \target tt-command
    \section1 \\tt (teletype font)

    The \\tt command renders its argument in a monospace font. This
    command behaves just like the \l {c-command} {\\c} command, except
    that \\tt allows you to nest QDoc commands within the argument
    (e.g. \l {e-command} {\\e}, \l {b-command} {\\b} and \l
    {underline-command} {\\underline}).

    \code
       / *!
           After having populated the main container with
           child widgets, \c setupUi() scans the main container's list of
           slots for names with the form
           \tt{on_\e{objectName}_\e{signalName}().}
       * /
    \endcode

    QDoc renders this as:

    \quotation
       After having populated the main container with
       child widgets, \c setupUi() scans the main container's list of
       slots for names with the form
       \tt{on_\e{objectName}_\e{signalName}().}
    \endquotation

    If the text to be rendered in the code font contains spaces, enclose the
    entire text in curly brackets.

    \code
      \tt {QLineEdit::QLineEdit(const QString &contents, QWidget *parent) :QWidget(parent)}
    \endcode

    QDoc renders this as:

    \quotation
      \tt {QLineEdit::QLineEdit(const QString &contents, QWidget *parent) :QWidget(parent)}
    \endquotation

    See also \l {c-command} {\\c}.

    \target b-command
    \section1 \\b

    The \\b command renders its argument in bold font. This command used
    to be called \\bold.

    \code
    / *!
        This is regular text; \b {this text is
        rendered using the \\b command}.
    * /
    \endcode

    QDoc renders this as:

    \quotation
    This is regular text; \b {this text is rendered using
    the \\b command}.
    \endquotation

    \target e-command
    \section1 \\e (emphasis, italics) \span {class="newStuff"} {(new 5/3/2012)}

    The \\e command renders its argument in a special font, normally italics. This
    command used to be called \\i, which is now deprecated. Use \e for italics.

    If the argument contains spaces or other punctuation, enclose the
    argument in curly brackets.

    \code
    / *!
        Here, we render \e {a few words} in italics.
    * /
    \endcode

    QDoc renders this as:

    \quotation
        Here, we render \e {a few words} in italics.
    \endquotation

    If you want to use other QDoc commands within an argument that
    contains spaces, you always need to enclose the argument in
    braces. But QDoc is smart enough to count parentheses [3], so you
    don't need braces in cases like this:

    \code
    / *!
        An argument can sometimes contain whitespaces,
        for example: \e QPushButton(tr("A Brand New Button"))
    * /
    \endcode

    QDoc renders this as:

    \quotation
       An argument can sometimes contain whitespaces,
       for example: \e QPushButton(tr("A Brand New Button"))
    \endquotation

    Finally, trailing punctuation is not included in an argument [4],
    nor is "'s" [5]

    \raw HTML
        <table align="center" cellpadding="2"
           cellspacing="1" border="0">

    \target sub-command
    \section1 \\sub

    The \\sub command renders its argument lower than the baseline of
    the regular text, using a smaller font.

    \code
    / *!
        Definition (Range): Consider the sequence
        {x\sub n}\sub {n > 1} . The set

        {x\sub 2, x\sub 3, x\sub 4, ...} = {x\sub n ; n = 2, 3, 4, ...}

        is called the range of the sequence.
    * /
    \endcode

    QDoc renders this as:

    \quotation
        Definition (Range): Consider the sequence
        {x\sub n}\sub {n > 1} . The set

        {x\sub 2, x\sub 3, x\sub 4, ...} = {x\sub n ; n = 2, 3, 4, ...}

        is called the range of the sequence.
    \endquotation

    If the argument contains spaces or other punctuation, enclose the
    argument in curly brackets.

    \target sup-command
    \section1 \\sup

    The \\sup command renders its argument higher than
    the baseline of the regular text, using a smaller font.

    \code
    / *!
        The series

        1 + a + a\sup 2 + a\sup 3 + a\sup 4 + ...

        is called the \i {geometric series}.

        The series

        1 + a + a\sup 2 + a\sup 3 + a\sup 4 + ...

        is called the \e {geometric series}.
    \endquotation

    If the argument contains spaces or other punctuation, enclose the
    argument in curly brackets.

    \target uicontrol-command
    \section1 \\uicontrol

    The \\uicontrol command is used to mark content as being used for UI
    control elements. When using HTML, the output is rendered in bold.
    When using DITA XML the content is enclosed in a \c{uicontrol} tag.

    \sa \\b

    \target underline-command
    \section1 \\underline

    The \\underline command renders its argument underlined.

    \code
    / *!
        The \underline {F}ile menu gives the users the possibility
        to edit an existing file, or save a new or modified
        file, and exit the application.
    * /
    \endcode

    QDoc renders this as:

    \quotation
        The \underline {F}ile menu gives the users the possibility
        to edit an existing file, or save a new or modified
        file, and exit the application.
    \endquotation

    If the argument contains spaces or other punctuation, enclose the
    argument in curly brackets.

    \target backslash-command
    \section1 \\\\ (double backslash)

    The \\\\ command expands to a double backslash.

    QDoc commands always start with a single backslash. To display a
    single backslash in the text you need to type two backslashes. If
    you want to display two backslashes, you need to type four.

    \code
    / *!
        The \\\\ command is useful if you want a
        backslash to appear verbatim, for example,
        writing C:\\windows\\home\\.
    * /
    \endcode

    QDoc renders this as:

    \quotation
        The \\\\ command is useful if you want a
        backslash to appear verbatim, for example,
        writing C:\\windows\\home\\.
    \endquotation

    However, if you want your text to appear in a monospace font as
    well, you can use the \l {c-command} {\\c} command instead, which
    accepts and renders the backslash as any other character. For
    example:

    \code
    / *!
        The \\c command is useful if you want a
        backslash to appear verbatim, and the word
        that contains it written in a monospace font,
        like this: \c {C:\windows\home\}.
    * /
    \endcode

    QDoc renders this as:

    \quotation
        The \\c command is useful if you want a
        backslash to appear verbatim, and the word
        that contains it written in a monospace font,
        like this: \c {C:\windows\home\}.
    \endquotation

    \title Document Structure

    The document structuring commands are for dividing your document
    into sections. QDoc supports six kinds of sections: \c \part, \c
    \chapter, \c \section1, \c \section2, \c \section3, and \c
    \section4. The \c \section1..4 commands are the most useful. They
    correspond to the traditional section, subsection, etc used in
    outlining.

    \target part-command
    \section1 \\part

    The \\part command is intended for use in a large document, like a
    book.

    In general a document structuring command considers everything
    that follows it until the first line break as its argument. The
    argument is rendered as the unit's title. If the title needs to be
    spanned over several lines, make sure that each line (except the
    last one) is ended with a backslash.

    In total, there are six levels of sections in QDoc: \c \part, \c
    \chapter, \c \section1, \c \section2, \c \section3 and \c
    \section4. \c \section1 to \c \section4 correspond to the
    traditional section, subsection, subsubsection and
    subsubsubsection.

    There is a strict ordering of the section units:

           \code
           part
              |
              chapter
                    |
                    section1
                           |
                           section2
                                  |
                                  section3
                                         |
                                         section4
           \endcode

    For example, a \c section1 unit can only appear as the top level
    section or inside a \c chapter unit. Skipping a section unit, for
    example from \c part to \c section1, is not allowed.

    You can \e begin with either of the three: \c part, \c chapter or
    \c section1.


           \code

    \title Including Code Inline

    The following commands are used to render source code without
    formatting. The source code begins on a new line, rendered in the
    code.

    \b{Note:} Although all these commands are for rendering C++
    code, the
    \l{07-0-qdoc-commands-includingexternalcode.html#snippet-command}
    {\\snippet} and
    \l{07-0-qdoc-commands-includingexternalcode.html#codeline-command}
    {\\codeline} commands are preferred over the others. These
    commands allow equivalent code snippets for other Qt language
    bindings to be substituted for the C++ snippets in the
    documentation.

    \target code-command
    \section1 \\code

    The \\code and \\endcode commands enclose a snippet of source code.

    \note The \l {c-command} {\\c} command can be used for short code
    fragments within a sentence. The \\code command is for longer code
    snippets. It renders the code verbatim in a separate paragraph in
    the code font.

    When processing any of the \\code, \l {newcode-command} {\\newcode} or \l
    {oldcode-command} {\\oldcode} commands, QDoc removes all
    indentation that is common for the verbatim code blocks within a
    \c{/}\c{*!} ... \c{*}\c{/} comment before it adds the standard
    indentation. For that reason the recommended style is to use 8
    spaces for the verbatim code contained within these commands

    \note This doesn't apply to externally quoted code using the \l
    {quotefromfile-command} {\\quotefromfile} or \l
    {quotefile-command} {\\quotefile} command.

           \code
           / *!
               \code
                   #include <QApplication>
                   #include <QPushButton>

                   int main(int argc, char *argv[])
                   {
                       ...
                   }
               \ endcode
           * /
           \endcode

           QDoc renders this as:

           \code
               #include <QApplication>
               #include <QPushButton>

               int main(int argc, char *argv[])
               {
                   ...
               }
           \endcode

    Other QDoc commands are disabled within \\code... \\endcode, and
    the special character '\\' is accepted and rendered like the rest
    of the code.

    To include code snippets from an external file, use the
    \l{07-0-qdoc-commands-includingexternalcode.html#snippet-command}
    {\\snippet} and
    \l{07-0-qdoc-commands-includingexternalcode.html#codeline-command}
    {\\codeline} commands.

    See also \l {c-command} {\\c}, \l
    {07-0-qdoc-commands-includingexternalcode.html#quotefromfile-command}
    {\\quotefromfile}, \l{newcode-command} {\\newcode}, and \l {oldcode-command}
    {\\oldcode}.

    \target newcode-command
    \section1 \\newcode

    The \\newcode, \\oldcode, and \\endcode commands enable you to
    show how to port a snippet of code to a new version of an API.

    The \\newcode command and its companion the \\oldcode command are
    a convenience combination of the \l {code-command} {\\code} commands:
    this combination provides a text relating the two code snippets to each
    other.

    The \\newcode command requires a preceding \\oldcode statement.

    Like the \l{code-command}{\\code} command, the \\newcode command renders its
    code on a new line in the documentation using a monospace font and the
    standard indentation.

           \code
           / *!
               \oldcode
                   if (printer->setup(parent))
                       ...
               \newcode
                   QPrintDialog dialog(printer, parent);
                       if (dialog.exec())
                           ...
               \ endcode
           * /
           \endcode

    QDoc renders this as:

           \quotation
               \oldcode
                   if (printer->setup(parent))
                       ...
               \newcode
                   QPrintDialog dialog(printer, parent);
                       if (dialog.exec())
                           ...
               \endcode
           \endquotation

    Other QDoc commands are disabled within \\oldcode ... \\endcode,
    and the '\\' character doesn't need to be escaped.

    \target oldcode-command
    \section1 \\oldcode

    The \\oldcode command requires a corresponding
    \\newcode statement; otherwise QDoc fails to parse the command
    and emits a warning.

    See also \l {newcode-command} {\\newcode}.

    \target qml-command
    \section1 \\qml

    The \\qml and \\endqml commands enclose a snippet of QML source
    code. Currently, QDoc handles \\qml and \\endqml in exactly the same
    way as \\code and \\endcode.

    \code
    / *!
        \qml
            import QtQuick 1.0

            Row {
                Rectangle {
                    width: 100; height: 100
                    color: "blue"
                    transform: Translate { y: 20 }
                }
                Rectangle {
                    width: 100; height: 100
                    color: "red"
                    transform: Translate { y: -20 }
                }
            }
        \endqml
    * /
    \endcode

    QDoc renders this as:

    \qml
        import QtQuick 1.0

        Row {
            Rectangle {
                width: 100; height: 100
                color: "blue"

    external files. You can make QDoc include the complete contents of
    a file, or you can quote specific parts of the file and skip
    others. The typical use of the latter is to quote a file chunk by
    chunk.

    \b{Note:} Although all these commands are for rendering C++
    code, the
    \l{07-0-qdoc-commands-includingexternalcode.html#snippet-command}
    {\\snippet} and
    \l{07-0-qdoc-commands-includingexternalcode.html#codeline-command}
    {\\codeline} commands are preferred over the others. These
    commands allow equivalent code snippets for other Qt language
    bindings to be substituted for the C++ snippets in the
    documentation.

    \target quotefile-command
    \section1 \\quotefile

    The \\quotefile command expands to the complete contents of the
    file given as argument.

    The command considers the rest of the line as part of its
    argument, make sure to follow the file name with a line break.

    The file's contents is rendered in a separate paragraph, using a
    monospace font and the standard indentation. The code is shown
    verbatim.

           \code
           / *!
               This is a simple "Hello world" example:

               \quotefile examples/main.cpp

               It contains only the bare minimum you need
               to get a Qt application up and running.
           * /
           \endcode

    QDoc renders this as:

           \quotation
               This is a simple "Hello world" example:

               application up and running.
           \endquotation

    \l {code-command} {\\code}.


    \target quotefromfile-command
    \section1 \\quotefromfile

    The \\quotefromfile command opens the file given as argument for
    quoting.

    The command considers the rest of the line as part of its
    argument, make sure to follow the file name with a line break.

    The command is intended for use when quoting parts from file with
    the walkthrough commands: \l {printline-command} {\\printline}, \l
    {printto-command} {\\printto}, \l {printuntil-command}
    {\\printuntil}, \l {skipline-command} {\\skipline}, \l
    {skipto-command} {\\skipto}, \l {skipuntil-command}
    {\\skipuntil}. This enables you to quote specific portions of a
    file.

           \code
           / *!
               The whole application is contained within
               the \c main() function:

               \quotefromfile examples/main.cpp

               \skipto main
               \printuntil app(argc, argv)

               First we create a QApplication object using
               the \c argc and \c argv parameters.

               \skipto QPushButton
               \printuntil resize

               Then we create a QPushButton, and give it a reasonable
               size using the QWidget::resize() function.

               ...
           * /
           \endcode

    QDoc renders this as:

           \quotation
               The whole application is contained within
               the \c main() function:

               \quotefromfile examples/main.cpp

               \skipto main
               \printuntil app(argc, argv)

               First we create a QApplication object using the \c argc
               and \c argv parameters.

               \skipto QPushButton
               \printuntil resize

               Then we create a QPushButton, and give it a reasonable
               size using the QWidget::resize() function.

               ...
           \endquotation

    QDoc remembers which file it is quoting from, and the current
    position in that file (see \l {file} {\\printline} for more
    information). There is no need to "close" the file.

    See also \l {quotefile-command} {\\quotefile}, \l {code-command}
    {\\code} and \l {dots} {\\dots}.

    \target printline-command
    \section1 \\printline

    The \\printline command expands to the line from the current
    position to the next non-blank line of the current source file.

    To ensure that the documentation remains synchronized with the
    source file, a substring of the line must be specified as an
    argument to the command. Note that the command considers the rest
    of the line as part of its argument, make sure to follow the
    substring with a line break.

    The line from the source file is rendered as a separate paragraph,
    using a monospace font and the standard indentation. The code is
    shown verbatim.

           \code
           / *!
               There has to be exactly one QApplication object
               in every GUI application that uses Qt.

               \quotefromfile examples/main.cpp

               \printline QApplication

               This line includes the QApplication class
               definition. QApplication manages various
               application-wide resources, such as the
               default font and cursor.

               \printline QPushButton

               This line includes the QPushButton class
               definition. The QPushButton widget provides a command
               button.

               \printline main

               The main function...
           * /

               \printline main

               The main function...
           \endquotation

    \target file

    QDoc reads the file sequentially. To move the current position
    forward you can use either of the \l {skipline-command}
    {\\skip...} commands. To move the current position backward, you
    can use the \l {quotefromfile-command} {\\quotefromfile} command
    again.

    \target substring

    If the substring argument is surrounded by slashes it is
    interpreted as a \l {QRegExp}{regular expression}.

           \code
           / *!
               \quotefromfile examples/mainwindow.cpp

               \skipto closeEvent
               \printuntil /^\}/

               Close events are sent to widgets that the users want to
               close, usually by clicking \c File|Exit or by clicking
               the \c X title bar button. By reimplementing the event
               handler, we can intercept attempts to close the
               application.
           * /
           \endcode

    QDoc renders this as:

           \quotation
               \quotefromfile examples/mainwindow.cpp

               \skipto closeEvent
               \printuntil /^\}/

               Close events are sent to widgets that the users want to
               close, usually by clicking \c File|Exit or by clicking
               the \c X title bar button. By reimplementing the event
               handler, we can intercept attempts to close the
               application.
           \endquotation

    (\l {widgets/scribble} {The complete example file...})

    The regular expression \c /^\}/ makes QDoc print until the first
    '}' character occurring at the beginning of the line without
    indentation. /.../ encloses the regular expression, and '^' means
    the beginning of the line. The '}' character must be escaped since
    it is a special character in regular expressions.

    QDoc will emit a warning if the specified substring or regular
    expression cannot be located, i.e. if the source code has changed.

    See also \l {printto-command} {\\printto} and \l
    {printuntil-command} {\\printuntil}.

    \target printto-command
    \section1 \\printto

    The \\printto command expands to all the lines from the current
    position up to and \e excluding the next line containing a given
    substring.

    The command considers the rest of the line as part of its
    argument, make sure to follow the substring with a line break. The
    command also follows the same conventions for \l {file}
    {positioning} and \l {substring} {argument} as the \l
    {printline-command} {\\printline} command.

    The lines from the source file are rendered in a separate
    paragraph, using a monospace font and the standard
    indentation. The code is shown verbatim.

    \target snippet-command
    \section1 \\snippet

    The \\snippet command causes a code snippet to be included
    verbatim as preformatted text, which may be syntax highlighted.

    Each code snippet is referenced by the file that holds it and by
    a unique identifier for that file. Snippet files are typically
    stored in a \c{snippets} directory inside the documentation
    directory (for example, \c{$QTDIR/doc/src/snippets}).

    For example, the following documentation references a snippet in a
    file residing in a subdirectory of the documentation directory:

           \code
           \snippet snippets/textdocument-resources/main.cpp Adding a resource
           \endcode

    The text following the file name is the unique identifier for the
    snippet. This is used to delimit the quoted code in the relevant
    snippet file, as shown in the following example that corresponds to
    the above \c{\\snippet} command:

           \dots
           \code
               QImage image(64, 64, QImage::Format_RGB32);
               image.fill(qRgb(255, 160, 128));

           //! [Adding a resource]
               document->addResource(QTextDocument::ImageResource,
                   QUrl("mydata://image.png"), QVariant(image));
           //! [Adding a resource]
           \endcode
           \dots

    \target codeline-command
    \section1 \\codeline

    The \\codeline command inserts a blank line of preformatted
    text. It is used to insert gaps between snippets without closing
    the current preformatted text area and opening a new one.

    \title Creating Links

    These commands are for creating hyperlinks to classes, functions,
    examples, and other targets.

    \target l-command
    \section1 \\l (link)

    The \\l link command is used to create a hyperlink to many
    different kinds of targets. The command's general syntax is:

    \code
      \l {link target} {link text}
    \endcode

    \code
       / *!
          Read the \l {http://doc.qt.io/qt-5/}
          {Qt 5.0 Documentation} carefully.
       * /
    \endcode

    QDoc renders this as:

    \quotation
       Read the \l {http://doc.qt.io/qt-5/}
       {Qt 5.0 Documentation} carefully.
    \endquotation

    If the link target is equivalent to the link text, the second
    argument can be omitted.

    For example, if you have documentation like:

    \code
      / *!
         \target assertions

         Assertions make some statement about the text at the
         point where they occur in the regexp, but they do not
         match any characters.

         ...

         Regexps are built up from expressions, quantifiers, and
         \l {assertions} {assertions}.
      * /
    \endcode

    You can simplify this as follows:

    \code
      / *!
        \target assertions

        Assertions make some statement about the text at the
        point where they occur in the regexp, but they do not
        match any characters.

        ...

        Regexps are built up from expressions, quantifiers, and
        \l assertions.
      * /
    \endcode

    For the one-parameter version, the braces can often be omitted.
    The \\l command supports several ways of linking:

    \list

    \li \c {\l QWidget} - The name of a class documented with the \l
    {class-command} {\\class} command.

    \li \c {\l QWidget::sizeHint()} - The name of a member function,
    documented with or without an \l {fn-command} {\\fn} command.

    \li \c {\l <QtGlobal>} - The subject of a \l {headerfile-command}
    {\\headerfile} command.

    \li \c {\l widgets/wiggly} - The relative path used in an \l
    {example-command} {\\example} command.

    \li \c {\l {QWidget Class Reference}} - The title used in a
    \l {title-command} {\\title} command.

    \li \c {\l {Introduction to QDoc}}- The text from one of the
    \l{part-command} {\\part}, \l{chapter} {\\chapter}, or \l
    {sectionOne-command} {\\section} commands.

    \li \c {\l fontmatching} - The argument of a \l {target-command}
    {\\target} command.

    \li \c {\l {Shared Classes}} - A keyword named in a \l
    {keyword-command} {\\keyword} command.

    \li \c {\l http://qt-project.org/} - A URL.

    \endlist

    QDoc also tries to make a link out of any word that doesn't
    resemble a normal English word, for example, Qt class names or
    functions, like QWidget or QWidget::sizeHint(). In these cases,
    the \\l command can actually be omitted, but by using the command,
    you ensure that QDoc will emit a warning if it cannot find the
    link target. In addition, if you only want the function name to
    appear in the link, you can use the following syntax:

    \list
        \li \c {\l {QWidget::} {sizeHint()}}
    \endlist

    QDoc renders this as:

    \quotation
    \l {QWidget::} {sizeHint()}
    \endquotation

    See also \l {sa-command} {\\sa}, \l {target-command} {\\target},
    and \l {keyword-command} {\\keyword}.


    \target sa-command
    \section1 \\sa (see also)

    The \\sa command defines a list of links that will be rendered in
    a separate "See also" section at the bottom of the documentation
    unit.

    The command takes a comma-separated list of links as its
    argument. If the line ends with a comma, you can continue
    the list on the next line. The general syntax is:

    \code
    \sa {the first link}, {the second link},
        {the third link}, ...
    \endcode

    QDoc will automatically try to generate "See also" links
    interconnecting a property's various functions. For example, a
    setVisible() function will automatically get a link to visible()
    and vice versa.

    In general, QDoc will generate "See also" links that interconnect
    the functions that access the same property. It recognizes four
    different syntax versions:

    \list
      \li \c property()
      \li \c setProperty()
      \li \c isProperty()
      \li \c hasProperty()
    \endlist

    The \\sa command supports the same kind of links as the \l
    {l-command} {\\l} command.

    \code
      / *!
         Appends the actions \a actions to this widget's
         list of actions.

         \sa removeAction(), QMenu, addAction()
      * /
      void QWidget::addActions(QList<QAction *> actions)
      {
      ...
      }
    \endcode

    QDoc renders this as:

    \quotation
        \b {void QWidget::addActions ( QList<QAction*>
        \e actions )}

        Appends the actions \e actions to this widget's list of
        actions.

        See also \l {QWidget::removeAction()} {removeAction()},
        \l QMenu, and \l {QWidget::addAction()} {addAction()}.
    \endquotation

    See also \l {l-command} {\\l}, \l {target-command} {\\target} and
    \l {keyword-command} {\\keyword}.


    \target target-command
    \section1 \\target

    The \\target command names a place in the documentation that you
    can link to using the \l {l-command} {\\l (link)} and \l
    {sa-command} {\\sa (see also)} commands.

    The text up to the line break becomes the target name. Be sure to
    follow the target name with a line break. Curly brackets are not
    required around the target name, but they may be required when the
    target name is used in a link command. See below.

    \code
    / *!
        \target capturing parentheses
        \section1 Capturing Text

        Parentheses allow us to group elements together so that
        we can quantify and capture them.

        ...
    * /
    \endcode

    The target name \e{capturing parentheses} can be linked from
    within the same document containing the target in the following way:

    \list
      \li \c {\l {capturing parentheses}} (from within the same QDoc comment)
    \endlist

    \note The brackets in the link example are required because the
    target name contains spaces.

    See also \l {l-command} {\\l}, \l {sa-command} {\\sa} and \l
    {keyword-command} {\\keyword}.

    \target keyword-command
    \section1 \\keyword

    The \\keyword command names a place in the documentation that you
    can link to using the \l {l-command} {\\l (link)} and \l
    {sa-command} {\\sa (see also)} commands.

    The \\keyword command is like the \l {target-command} {\\target}
    command, but stronger. A keyword can be linked from anywhere using
    a simple syntax.

    Keywords must be unique over all the documents processed during
    the QDoc run. The command uses the rest of the line as its
    argument. Be sure to follow the keyword with a line break.


    \code
    / *!
        \class QRegExp
        \reentrant
        \brief The QRegExp class provides pattern
               matching using regular expressions.
        \ingroup tools
        \ingroup misc
        \ingroup shared
        \mainclass

        \keyword regular expression

        Regular expressions, or "regexps", provide a way to
        find patterns within text.

        ...
    * /
    \endcode

    The location marked with the keyword can be linked to with:

    \code
    / *!
        When a string is surrounded by slashes, it is
        interpreted as a \l {QRegExp}{regular expression}.
    * /
    \endcode

    QDoc renders this as:

    \quotation
        When a string is surrounded by slashes, it is
        interpreted as a \l {regular expression}.
    \endquotation

    If the keyword text contains spaces, the brackets are required.

    See also \l {l-command} {\\l (link)}, \l {sa-command} {\\sa (see
    also)} and \l {target-command} {\\target}.

    \title Including Images

    The graphic commands makes it possible to include images in the
    documentation. The images can be rendered as separate paragraphs,
    or within running text.

    \target image-command
    \section1 \\image

    The \\image command expands to the image specified by its first
    argument, and renders it centered as a separate paragraph.

    The command takes two arguments. The first argument is the name of
    the image file. The second argument is optional and is a simple
    description of the image, equivalent to the HTML alt="" in an image
    tag. The description is used for tooltips and for browsers that don't
    support images, like the Lynx text browser.

    The remaining text \e{after} the file name is the optional,
    description argument. Be sure to follow the file name or the
    description with a line break. Curly brackets are required if the
    description argument spans multiple lines.

    \code
    / *!

    See also \l {inlineimage-command} {\\inlineimage} and \l
    {caption-command} {\\caption}.

    \target inlineimage-command
    \section1 \\inlineimage

    The \\inlineimage command expands to the image specified by its
    argument. The image is rendered inline with the rest of the text.

    The command takes two arguments. The first argument is the name of
    the image file. The second argument is optional and is a simple
    description of the image, equivalent to the HTML alt="" in an image
    tag. The description is used for tooltips, and for when a browser
    doesn't support images, like the Lynx text browser.

    The most common use of the \\inlineimage command is in lists and
    tables. Here is an example of including inline images in a list:

    \code
    / *!
        \list 1
          \li \inlineimage happy.gif Oh so happy!
          \li \inlineimage happy.gif Oh so happy!
          \li \inlineimage happy.gif Oh so happy!
        \endlist
    * /
    \endcode

    QDoc renders this as:

    \list 1
      \li \inlineimage happy.gif Oh so happy!
      \li \inlineimage happy.gif Oh so happy!
      \li \inlineimage happy.gif Oh so happy!
    \endlist

    Here is an example of including inline images in a table:

    \code
    / *!
        \table
        \header
            \li Qt
            \li Qt Creator
        \row
            \li \inlineimage happy.gif Oh so happy!
            \li \inlineimage happy.gif Oh so happy!
        \row
            \li \inlineimage happy.gif Oh so happy!
            \li \inlineimage happy.gif Oh so happy!
        \endtable
    * /
    \endcode

    QDoc renders this as:

    \raw HTML
        <table align="center" cellpadding="2"
            cellspacing="1" border="0">
        <tr valign="top" bgcolor="#a2c511">
            <th>Qt</th>
            <th>Qt Creator</th>
        </tr>
        <tr valign="top" bgcolor="#f0f0f0">
            <td><img src="images/happy.gif" alt="Oh so happy!" />
            </td>
            <td><img src="images/happy.gif" alt="Oh so happy!" />
            </td>
        </tr>
        <tr valign="top" bgcolor="#f0f0f0">
            <td><img src="images/happy.gif" alt="Oh so happy!"/>
            </td>
            <td><img src="images/happy.gif" alt="Oh so happy!" />
            </td>
        </tr>
        </table>
    \endraw

    The command can also be used to insert an image inline with the
    text.

    \title Tables and Lists

    These commands enable creating lists and tables. A list is
    rendered left aligned as a separate paragraph. A table is rendered
    centered as a separate paragraph. The table width depends on the
    width of its contents.

    \target table-command
    \section1 \\table

    The \\table and \\endtable commands delimit the contents of a
    table.

    The command accepts a single argument specifying the table's width
    as a percentage of the page width:

           \code
           / *!
               \table 100 %

                  ...

               \endtable
           * /
           \endcode

    The code above ensures that the table will fill all available
    space. If the table's width is smaller than 100 %, the table will
    be centered in the generated documentation.

    A table can contain headers, rows and columns. A row starts with a
    \l {row-command} {\\row} command and consists of cells, each of which
    starts with an \l {li-command} {\\li} command. There is also a \l
    {header-command} {\\header} command which is a special kind of row
    that has a special format.

           \code
           / *!
               \table

                      but only one row
                   \li {1, 2} This table cell spans only one column,

    \target header-command
    \section1 \\header

    The \\header command indicates that the following table cells are
    the current table's column headers.

    The command can only be used within the \l{table-command}
    {\\table...\\endtable} commands. A header can contain several
    cells. A cell is created with the \l {li-command} {\\li} command.

    A header cell's text is centered within the table cell and
    rendered using a bold font.

    \target row-command
    \section1 \\row

    The \\row command begins a new row in a table. The \l {li-command}
    {\\li items} that belong in the new row will immediately follow the
    \\row.

    The command can only be used within the \l{table-command}
    {\\table...\\endtable} commands. A row can contain several
    cells. A cell is created with the \l {li-command} {\\li} command.

    The background cell color of each row alternates between two
    shades of grey, making it easier to distinguish the rows from each
    other. The cells' contents is left aligned.

    \target value-command
    \section1 \\value

    The \\value command starts the documentation of a C++ enum item.

    The command's first argument is the enum item. Then follows its
    associated description. The description argument ends at the next
    blank line or \\value. The arguments are rendered within a table.

    The documentation will be located in the associated class, header
    file or namespace documentation. See the \l {enum-command}
    {\\enum} documentation for an example.

    \note Since Qt 5.4, \\value command can also be used outside the
    \l {enum-command} {\\enum} topic. In this case, QDoc renders a
    two-column table listing the constant name (taken as-is from the
    first argument) and its description. This can be used, for
    example, in \l {qmlproperty-command}{\\qmlproperty} topic for
    documenting acceptable values for a QML enumeration property.

    See also \l {enum-command} {\\enum} and \l {omitvalue-command} {\\omitvalue}.

    \target omitvalue-command
    \section1 \\omitvalue

    The \\omitvalue command excludes a C++ enum item from the
    documentation.

    The command's only argument is the name of the enum item that will
    be omitted. See the \l {enum-command} {\\enum} documentation for
    an example.

    See also \l {enum-command} {\\enum} and \l {value-command}
    {\\value}.

    \target list-command
    \section1 \\list

    The \\list and \\endlist commands delimit a list of items.

    Create each list item with the \l {li-command} {\\li} command. A
    list always contains one or more items. Lists can be nested. For
    example:

           \code
           / *!
               \list
               \li Qt Reference Documentation: Getting Started
                   \list
                   \li How to Learn Qt
                   \li Installation
                       \list
                       \li Qt/X11
                       \li Qt/Windows
                       \li Qt/Mac
                       \li Qt/Embedded
                       \endlist
                   \li Tutorial and Examples
                   \endlist
               \endlist
           * /
           \endcode

    QDoc renders this as:

           \list
           \li Qt Reference Documentation: Getting Started
               \list
               \li How to Learn Qt
               \li Installation
                   \list
                   \li Qt/X11
                   \li Qt/Windows
                   \li Qt/Mac
                   \li Qt/Embedded
                   \endlist
               \li Tutorial and Examples
               \endlist
           \endlist

    The \\list command takes an optional argument providing
    alternative appearances for the list items.

           \code
           / *!
               \list
                   \li How to Learn Qt
                   \li Installation
                   \li Tutorial and Examples
               \endlist
           * /
           \endcode

     QDoc renders the list items with bullets (the default):

           \list
               \li How to Learn Qt
               \li Installation
               \li Tutorial and Examples
           \endlist

    \warning There appears to be a bug in qdoc here. If you include
    any of the argument types, you get a numeric list. We're looking
    into it.

    If you provide 'A' as an argument to the \\list command, the
    bullets are replaced with characters in alphabetical order:

           \list A
               \li How to Learn Qt
               \li Installation
               \li Tutorial and Examples
           \endlist

     If you replace 'A' with '1', the list items are numbered in
     ascending order:

           \list 1
               \li How to Learn Qt
               \li Installation
               \li Tutorial and Examples

           \endlist

    If you provide 'i' as the argument, the bullets are replaced with
    roman numerals:

           \list i
               \li How to Learn Qt
               \li Installation
               \li Tutorial and Examples
           \endlist

    Finally, you can make the list items appear with roman numbers
    following in ascending order if you provide 'I' as the optional
    argument:

           \list I
               \li How to Learn Qt
               \li Installation
               \li Tutorial and Examples
           \endlist

    You can also make the listing start at any character or number by
    simply provide the number or character you want to start at. For
    example:

           \code
           / *!
               \list G
                   \li How to Learn Qt
                   \li Installation
                   \li Tutorial and Examples
               \endlist
           * /
           \endcode

    \note This doesn't work in DITA XML, so don't use it because it
    produces a DITA XML file that doesn't validate. There probably is
    a way to do this in DITA, so if we figure it out, we will put it
    in. But this capability is not used anywhere other than right
    here, so it probably isn't important. For now, if you use this
    option, qdoc will ignore it and produce a list without it.

    QDoc renders this as:

           \list G
               \li How to Learn Qt
               \li Installation
               \li Tutorial and Examples
           \endlist

    See also \l {li-command} {\\li}.

    \target li-command
    \section1 \\li (table cell, list item)

    The \\li command marks a table cell or a list item. This command
    is only used in \l{table-command} {tables} and \l{list-command}
    {lists}.

    It considers everything as its argument until the next \\li command, until the
    next \l {table-command} {\\endtable}, or \l {list-command} {\\endlist}
    command. See \l {table-command} {\\table} and \l {list-command} {\\list}
   for examples.

    If the command is used within a table, you can also specify
    how many rows or columns the item should span.

           \code
           / *!
               \table
               \header
                   \li {3,1} This header cell spans three columns
                      but only one row.
               \row
                   \li {2, 1} This table item spans two columns
                      but only one row
                   \li {1, 2} This table item spans only one column,
                   but two rows.
               \row
                   \li A regular table item
                   \li A regular table item
               \endtable
           * /
           \endcode

    QDoc renders this as:

           \raw HTML
               <table align="center" cellpadding="2" cellspacing="1"

               </tr>

               </table>

    If not specified, the item will span one column and one row.

    \title Special Content

    The document contents commands identify parts of the documentation,
    parts with a special rendering, conceptual meaning or
    function.

    \target abstract-command
    \section1 \\abstract

    The \\abstract and \\endabstract commands delimit a
    document's abstract section.

    The abstract section is rendered as an indented italicized
    paragraph.

    \warning The \b{\\abstract} and \b{\\endabstract} commands
    have not been implemented. The abstract section is rendered as a
    regular HTML paragraph.

    \target quotation-command
    \section1 \\quotation

    The \\quotation and \\endquotation commands delimit a long quotation.

    The text in the delimited block is surrounded by
    \b{<blockquote>} and \b{</blockquote>} in the html output,
    e.g.:

        \code
        / *!
          Although the prospect of a significantly broader market is
          good news for Firstlogic, the notion also posed some
          challenges. Dave Dobson, director of technology for the La
          Crosse, Wisconsin-based company, said:

          \quotation
             As our solutions were being adopted into new
             environments, we saw an escalating need for easier
             integration with a wider range of enterprise
             applications.
          \endquotation
        * /
        \endcode

    The text in the \b{\\quotation} block will appear in the generated HTML as:

    \code
    <blockquote>
      <p>As our solutions were being adopted into new environments,
      we saw an escalating need for easier integration with a wider
      range of enterprise applications.</p>
        </blockquote>
    \endcode

    The built-in style sheet for most browsers will render the
    contents of the <blockquote> tag with left and right
    indentations. The example above would be rendered as:

          \quotation
             As our solutions were being adopted into new
             environments, we saw an escalating need for easier
             integration with a wider range of enterprise
             applications.
          \endquotation

    But you can redefine the \b{<blockquote>} tag in your style.css file.

    \target footnote-command
    \section1 \\footnote

    The \\footnote and \\endfootnote commands delimit a footnote.

    The footnote is rendered at the bottom of the page.

    \warning The \b{\\footnote} and \b{\\endfootnote} commands
    have not been implemented. The footnote is rendered as a regular
    HTML paragraph.

    \target note-command
    \section1 \\note

    The \\note command defines a new paragraph preceded by "Note:"
    in bold.

    \target tableofcontents-command
    \section1 \\tableofcontents

    The \\tableofcontents command has been disabled because QDoc
    now generates a table of contents automatically.

    The automatically generated table of contents appears in the upper
    righthand corner of the page.

    \target brief-command
    \section1 \\brief

    The \\brief command introduces a one-sentence description of a
    class, namespace, header file, property, or variable.

    The brief text is used to introduce the documentation of the
    associated object, and in lists generated using the \l
    {generatelist-command} {\\generatelist} command and the \l
    {annotatedlist-command} {\\annotatedlist} command.

    The \\brief command can be used in two significant different ways:
    \l {brief class} {One for classes, namespaces and header files},
    and \l {brief-property} {one for properties and variables}.

    \target brief-property

    When the \\brief command is used to describe a property or a
    variable, the brief text must be a sentence fragment starting with
    "whether" (for a boolean property or variable) or starting with
    "the" (for any other property or variable).

    For example the boolean QWidget::isWindow property:

           \code
           / *!
               \property QWidget::isActiveWindow
               \brief Whether this widget's window is the active window

               The active window is the window that contains the widget that
               has keyboard focus.

               When popup windows are visible, this property is \c true
               for both the active window \e and the popup.

               \sa activateWindow(), QApplication::activeWindow()
           * /
           \endcode

           and the QWidget::geometry property

           \code
           / *!
               \property QWidget::geometry
               \brief The geometry of the widget relative to its parent and
               excluding the window frame

               When changing the geometry, the widget, if visible,
               receives a move event (moveEvent()) and/or a resize
               event (resizeEvent()) immediately.

               ...

              \sa frameGeometry(), rect(), ...
           * /
           \endcode

    QDoc renders this as:

           \quotation
               \raw HTML
                   <h3>geometry :

                   </h3>
               \endraw

               This property holds the geometry of the widget relative
               to its parent and excluding the window frame.

               ...

               Access functions:

    \target brief class

    When the \\brief command is used to describe a class, we recommend
    using a complete sentence like this:

           \code
           The <classname> class is|provides|contains|specifies...
           \endcode

    \warning Do not repeat your detailed description with the same sentence as
    the brief statement will be the first paragraph of the detailed
    description.

    If the \\endlegalese command is omitted, QDoc will process the
    \\legalese command but considers the rest of the documentation
    page as the license agreement.

    Ideally, the license text is located with the licensed code.

   Elsewhere, the documentation identified as \e{\\legalese} command
   can be accumulated using \l {generatelist-command} {\\generatelist}
   with \c {legalese-command} as the argument. This is useful for
   generating an overview of the license agreements associated with
   the source code.

    \target warning-command

    \title Miscellaneous

    These commands provide miscellaneous functions connected to the
    visual appearance of the documentation, and to the process of
    generating the documentation.

    \target annotatedlist-command
    \section1 \\annotatedlist

    The \\annotatedlist command expands to a list of the members of a
    group, each member listed with its \e {brief} text. Below is an
    example from the Qt Reference Documentation:

           \code
           / *!
               ...
               \section1 Drag and Drop Classes

               These classes deal with drag and drop and the necessary mime type
               encoding and decoding.

               \annotatedlist draganddrop

           * /
           \endcode

    This generates a list of all the C++ classes and/or QML types in
    the \e{draganddrop} group. A C++ class or QML type in the
    \e{draganddrop} group will have \e{\\ingroup draganddrop} in its
    \e{\\class} or \e{\\qmltype} comment.


    \target generatelist-command
    \section1 \\generatelist

    The \\generatelist command expands to a list of links to the
    documentation entities in a group. Below is an example from the Qt
    Reference Documentation:

           \code
           / *!
               \page classes.html
               \title All Classes

               For a shorter list that only includes the most
               frequently used classes, see \l{Qt's Main Classes}.

               \generatelist classes Q
           * /
           \endcode

    This generates the \e {All Classes} page. The command accepts the
    following arguments:

    \target table example
    \section2 \c annotatedclasses

    The \c annotatedclasses argument provides a table containing the
    names of all the classes, and a description of each class. Each
    class name is a link to the class's reference documentation. For
    example:

    \table
      \row
        \li QDial
    \li Rounded range control (like a speedometer or potentiometer)
      \row
        \li QDialog
    \li The base class of dialog windows
      \row
        \li QDir
        \li Access to directory structures and their contents
    \endtable

    A C++ class is documented with the \l {class-command} {\\class}
    command. The annotation for the class is taken from the argument
    of the class comment's \l {brief-command} {\\brief} command.

    \target list example
    \section2 \c {classes <prefix>}

    The \c classes argument provides a complete alphabetical list of
    the classes. The second argument, \c{<prefix>}, is the common
    prefix for the class names. The class names will be sorted on the
    character that follows the common prefix. e.g. The common prefix
    for the Qt classes is \c Q. The common prefix argument is
    optional.  If no common prefix is provided, the class names will
    be sorted on their first character.

    Each class name becomes a link to the class's reference
    documentation. This command is used to generate the
    \e {All Classes} page this way:

    \code
    / *!
        \page classes.html
        \title All Classes
        \ingroup classlists

        \brief Alphabetical list of classes.

        This is a list of all Qt classes. For a list of the classes
        provided for compatibility with Qt3, see \l{Qt3 Support
        Classes}. For classes that have been deprecated, see the
        \l{Obsolete Classes} list.

        \generatelist classes Q
    * /
    \endcode

    A C++ class is documented with the \l {class-command} {\\class}
    command.

    \section2 \c classesbymodule

    When this argument is used, a second argument is required, which
    specifies the module whose classes are to be listed. QDoc
    generates a table containing those classes. Each class is listed
    with the text of its \l{brief-command} {\\brief} command.

    For example, this command can be used on a module page as follows:

    \code
      / *!
          \page phonon-module.html
          \module Phonon
          \title Phonon Module
          \ingroup modules

          \brief Contains namespaces and classes for multimedia functionality.

          \generatelist{classesbymodule Phonon}

      ...

      * /
    \endcode

    Each class that is a member of the specified module must be marked
    with the \l {inmodule-command} {\\inmodule} command in its \\class
    comment.

    \section2 \c compatclasses

    The \c compatclasses argument generates a list in alphabetical
    order of the support classes. It is normally used only to
    generate the Qt3 Support Classes page this way:

    \code
    / *!
        \page compatclasses.html
        \title Qt3 Support Classes
        \ingroup classlists

        \brief Enable porting of code from Qt 3 to Qt 4.

        These are the classes that Qt provides for compatibility with Qt
        3. Most of these are provided by the Qt3Support module.

        \generatelist compatclasses
    * /
    \endcode

    A support class is identified in the \\class comment with the \l
    {compat-command} {\\compat} command.

    \section2 \c functionindex

    The \c functionindex argument provides a complete alphabetical
    list of all the documented member functions. It is normally used
    only to generate the \e {Qt function index} page
    this way:

    \code
    / *!
        \page functions.html
        \title All Functions
        \ingroup funclists

        \brief All documented Qt functions listed alphabetically with a
        link to where each one is declared.

        This is the list of all documented member functions and global
        functions in the Qt API. Each function has a link to the
        class or header file where it is declared and documented.

        \generatelist functionindex
    * /
    \endcode

    \section2 \c legalese

    The \c legalese argument tells QDoc to generate a complete list of
    licenses in the documentation. Each license is identified using
    the \l {legalese-command} {\\legalese} command. This command is
    used to generate the \e {Qt license information}
    page this way:

    \code
    / *!
        \page licenses.html
        \title Other Licenses Used in Qt
        \ingroup licensing
        \brief Information about other licenses used for Qt components and third-party code.

        Qt contains some code that is not provided under the
        \l{GNU General Public License (GPL)},
        \l{GNU Lesser General Public License (LGPL)} or the
        \l{Qt Commercial Edition}{Qt Commercial License Agreement}, but rather under
        specific licenses from the original authors. Some pieces of code were developed
        by Digia and others originated from third parties.
        This page lists the licenses used, names the authors, and links
        to the places where it is used.

        Digia gratefully acknowledges these and other contributions
        to Qt. We recommend that programs that use Qt also acknowledge
        these contributions, and quote these license statements in an
        appendix to the documentation.

        See also: \l{Licenses for Fonts Used in Qt for Embedded Linux}

        \generatelist legalese
    * /
    \endcode

    \section2 \c mainclasses

    The \c mainclasses argument tells QDoc to generate an alphabetical
    list of the main classes. A class is marked as a main class by
    including a \l {mainclass-command} {\\mainclass} command in the
    \\class comment.

    \note The Qt documentation no longer includes a main classes page,
    but you can generate one for your main classes if you want it.

    \section2 \c overviews

    The \c overviews argument is used to tell QDoc to generate a list
    by concatenating the contents of all the \l {group-command}
    {\\group} pages. Qt uses it to generate the \e {overviews} page

    \section2 \c related

    The \c related argument is used in combination with the \l
    {group-command} {\\group} and \l {ingroup-command} {\\ingroup}
    commands to list all the overviews related to a specified
    group. For example, the page for the \e {Programming with Qt}
    page is generated this way:

    \code
    / *!
        \group qt-basic-concepts
        \title Programming with Qt

        \brief The basic architecture of the Qt cross-platform application and UI framework.

        Qt is a cross-platform application and UI framework for
        writing web-enabled applications for desktop, mobile, and
        embedded operating systems. This page contains links to
        articles and overviews explaining key components and
        techniuqes used in Qt development.

        \generatelist {related}
    * /
    \endcode

    Each page listed on this group page contains the command:

    \code
        \ingroup qt-basic-concepts
    \endcode

    \section2 \c service

    The \c service argument tells QDoc to generate an alphabetical
    list of the services. Each service name is a link to the service's
    reference documentation.

    A service is identified with the \l {service-command} {\\service}
    command.

    \note This command and the \l {service-command} {\\service}
    command are not used in the Qt documentation.

    \target if-command
    \section1 \\if

    The \\if command and the corresponding \\endif command
    enclose parts of a QDoc comment that only will be included if
    the condition specified by the command's argument is true.

    The command reads the rest of the line and parses it as an C++ #if
    statement.

           \code
           / *!
               \if defined(opensourceedition)

               \b{Note:} This edition is for the development of
               \l{Qt Open Source Edition} {Free and Open Source}
               software only; see \l{Qt Commercial Editions}.

               \endif
           * /
           \endcode

    This QDoc comment will only be rendered if the \c
    opensourceedition preprocessor symbol is defined, and specified in
    the \l {defines-variable} {defines} variable in the configuration
    file to make QDoc process the code within #ifdef and #endif:

           \code
               defines = opensourceedition
           \endcode

    You can also define the preprocessor symbol manually on the
    command line. For more information see the documentation of the \l
    {defines-variable} {defines} variable.

    See also \l{endif-command} {\\endif}, \l{else-command} {\\else},
    \l {defines-variable} {defines} and \l {falsehoods-variable}
    {falsehoods}.

    \target endif-command
    \section1 \\endif

    The \\endif command and the corresponding \\if command
    enclose parts of a QDoc comment that will be included if
    the condition specified by the \l {if-command} {\\if} command's
    argument is true.

    For more information, see the documentation of the \l {if-command}
    {\\if} command.

    See also \l{if-command} {\\if}, \l{else-command} {\\else}, \l
    {defines-variable} {defines} and \l {falsehoods-variable}
    {falsehoods}.

    \target else-command
    \section1 \\else

    The \\else command specifies an alternative if the
    condition in the \l {if-command} {\\if} command is false.

    The \\else command can only be used within \l {if-command}
    {\\if...\\endif} commands, but is useful when there is only two
    alternatives.

           \code
           / *!
               The Qt 3 support library is provided to keep old
               source code working.

               In addition to the \c Qt3Support classes, Qt 4 provides
               compatibility functions when it's possible for an old
               API to cohabit with the new one.

               \if !defined(QT3_SUPPORT)
                   \if defined(QT3_SUPPORTWARNINGS)
                       The compiler emits a warning when a
                       compatibility function is called. (This works
                       only with GCC 3.2+ and MSVC 7.)
                   \else
                       To use the Qt 3 support library, you need to
                       have the line QT += qt3support in your .pro
                       file (qmake automatically define the
                       QT3_SUPPORT symbol, turning on compatibility
                       function support).

                       You can also define the symbol manually (for example,
                       if you don't want to link against the \c
                       Qt3Support library), or you can define \c
                       QT3_SUPPORT_WARNINGS instead, telling the
                       compiler to emit a warning when a compatibility
                       function is called. (This works only with GCC
                       3.2+ and MSVC 7.)
                   \endif
               \endif
           * /
           \endcode

    If the \c QT3_SUPPORT is defined, the comment will be rendered
    like this:

           \quotation
               The Qt 3 support library is provided to keep old source
               code working.

               In addition to the Qt3Support classes, Qt 4 provides
               compatibility functions when it's possible for an old
               API to cohabit with the new one.
           \endquotation

    If \c QT3_SUPPORT is not defined but \c QT3_SUPPORT_WARNINGS is
    defined, the comment will be rendered like this:

           \quotation
               The Qt 3 support library is provided to keep old source
               code working.

               In addition to the Qt3Support classes, Qt 4 provides
               compatibility functions when it's possible for an old
               API to cohabit with the new one.

               The compiler emits a warning when a compatibility
               function is called. (This works only with GCC 3.2+ and
               MSVC 7.)
           \endquotation

           If none of the symbols are defined, the comment will be
           rendered as

           \quotation
               The Qt 3 support library is provided to keep old
               source code working.

               In addition to the \c Qt3Support classes, Qt 4 provides
               compatibility functions when it's possible for an old
               API to cohabit with the new one.

               To use the Qt 3 support library, you need to have the
               line QT += qt3support in your .pro file (qmake
               automatically define the QT3_SUPPORT symbol, turning on
               compatibility function support).

               You can also define the symbol manually (e.g., if you
               don't want to link against the \c Qt3Support library),
               or you can define \c QT3_SUPPORT_WARNINGS instead,
               telling the compiler to emit a warning when a
               compatibility function is called. (This works only with
               GCC 3.2+ and MSVC 7.)
           \endquotation

           See also \l{if-command} {\\if}, \l{endif-command} {\\endif}, \l
           {defines-variable} {defines} and \l {falsehoods-variable}
           {falsehoods}.

    \target include-command
    \section1 \\include

    The \\include command sends all or part of the file specified by
    its first argument to the QDoc input stream to be processed as a
    QDoc comment snippet. This command is often assigned the alias,
    \e {input}, in the QDoc configuration file, for example \e {alias.include
    = input}.

    The command is useful when some snippet of commands and text is to
    be used in multiple places in the documentation. In that case,
    move the snippet into a separate file and use the \\include
    command wherever you want to insert the snippet into the
    documentation. To prevent QDoc from reading the file as a
    stand-alone page of documentation, we recommend that you use the
    \c .qdocinc extension for these \e {include} files.

    The command can have either one or two arguments. The first
    argument is always a file name. The contents of the file must be
    QDoc input, in other words, a sequence of QDoc commands and text, but
    without the enclosing QDoc comment \c{/}\c{*!} ... \c{*}\c{/} delimiters.
    If you want to include the entire named file, don't use the second
    argument. If you want to include only part of the file, see the
    \l{2-argument-form}{two argument form} below. Here is an example
    of the one argument form:

            \code
            / *!
                \page corefeatures.html
                \title Core Features

                \include examples/signalandslots.qdocinc
                \include examples/objectmodel.qdocinc
                \include examples/layoutmanagement.qdocinc
            * /
            \endcode

    QDoc renders this page \l{corefeatures.html} {as shown here}.

    \target 2-argument-form}
    \section2 \\include filename snippet-identifier

    It is a waste of time to make a separate \c .qdocinc file for every
    QDoc include snippet you want to use in multiple places in the
    documentation, especially given that you probably have to put the
    copyright/license notice in every one of these files. So if you
    have a large number of snippets to be included, you can put them all in a
    single file if you want, and surround each one with:
    \code
        //! [snippet-id1]

           QDoc commands and text...

    //! [snippet-id1]

        //! [snippet-id2]

           More QDoc commands and text...

    //! [snippet-id2]
    \endcode

    Then you can use the two-argument form of the command:

    \code
        \input examples/signalandslots.qdocinc snippet-id2
        \input examples/objectmodel.qdocinc another-snippet-id
    \endcode

    It works as expected. The sequence of QDoc commands and text found
    between the two tags with the same name as the second argument is
    sent to the QDoc input stream. You can even nest these snippets,
    although it's not clear why you would want to do that.

    \target meta-command
    \section1 \\meta

    The \\meta command is mainly used for including metadata in DITA
    XML files. It is also used when generating HTML output for specifying
    the \e maintainer(s) of a C++ class.

    The command has two arguments: the first argument is the name of the
    metadata attribute, and the second argument is the
    value for the attribute. Each argument should be enclosed in curly
    brackets, as shown in this example:

    \code
    / *!
        \class QWidget
        \brief The QWidget class is the base class of all user interface objects.

        \ingroup basicwidgets

        \meta {technology} {User Interface}
        \meta {platform} {OS X 10.6}
        \meta {platform} {Symbian}
        \meta {platform} {MeeGo}
        \meta {audience} {user}
        \meta {audience} {programmer}
        \meta {audience} {designer}
    * /
    \endcode

    When running QDoc to generate HTML, the example above will have no
    effect on the generated output, but if you run QDoc to generate
    DITA XML, the example will generate the following:

    \code
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE cxxClass PUBLIC "-//NOKIA//DTD DITA C++ API Class Reference Type v0.6.0//EN" "dtd/cxxClass.dtd">

               <othermeta name="technology" content="User Interface"/>
           </metadata>
       </prolog>
    \endcode

    In the example output, several values have been set using default
    values obtained from the QDoc configuration file. See \l
    {Generating DITA XML Output} for details.

    \target omit-command
    \section1 \\omit

    The \\omit command and the corresponding \\endomit command
    delimit parts of the documentation that you want QDoc to skip. For
    example:

            \code
            / *!
                \table
                \row
                    \li Basic Widgets
                    \li Basic GUI widgets such as buttons, comboboxes
                       and scrollbars.

                \omit
                \row
                    \li Component Model
                    \li Interfaces and helper classes for the Qt
                       Component Model.
                \endomit

                \row
                    \li Database Classes
                    \li Database related classes, e.g. for SQL databases.
                \endtable
            * /
            \endcode

    QDoc renders this as:

            \raw HTML
                <table align="center" cellpadding="2"
                    cellspacing="1" border="0">

                <tr valign="top" bgcolor="#d0d0d0">
                    <td>Basic Widgets</td>
                    <td>Basic GUI widgets such as buttons, comboboxes
                       and scrollbars.</td>
                </tr>

                <tr valign="top" bgcolor="#c0c0c0">
                    <td>Database Classes</td>
                    <td>Database related classes, e.g. for SQL databases.</td>
                </tr>
                </table>
            \endraw

    \target raw-command
    \section1 \\raw \span {class="newStuff"} {(avoid)}

    The \\raw command and the corresponding
    \\endraw command delimit a block of raw mark-up language code.

    \note Avoid using this command if possible, because it generates
    DITA XML code that causes problems. If you are trying to generate
    special table or list behavior, try to get the behavior you want
    using the \l {span-command} {\\span} and \l {div-command} {\\div}
    commands in your \l {table-command} {\\table} or \l {list-command}
    {\\list}.

    The command takes an argument specifying the code's format.
    Currently, the only supported format is HTML.

    The \\raw command is useful if you want some special HTML effects
    in your documentation.

           \code
           / *!
               Qt has some predefined QColor objects.

               \raw HTML
               <style type="text/css" id="colorstyles">
               #color-blue { background-color: #0000ff; color: #ffffff }
               #color-darkBlue { background-color: #000080; color: #ffffff }
               #color-cyan { background-color: #00ffff; color: #000000 }
               </style>

               <p>
               <tt id="color-blue">Blue(#0000ff)</tt>,
               <tt id="color-darkBlue">dark blue(#000080)</tt> and
               <tt id="color-cyan">cyan(#00ffff)</tt>.
           </p>
               \endraw
           * /
           \endcode

    QDoc renders this as:

           \quotation
               Qt has some predefined QColor objects.

               \raw HTML
               <style type="text/css" id="colorstyles">
               #color-blue { background-color: #0000ff; color: #ffffff }
               #color-darkBlue { background-color: #000080; color: #ffffff }
               #color-cyan { background-color: #00ffff; color: #000000 }
               </style>

               <p>
               <tt id="color-blue">Blue(#0000ff)</tt>,
               <tt id="color-darkBlue">dark blue(#000080)</tt> and
               <tt id="color-cyan">cyan(#00ffff)</tt>.
           </p>
               \endraw
           \endquotation

    \note But you can achieve the exact same thing using qdoc
    commands. In this case, all you have to do is include the color
    styles in your style.css file. Then you can write:

       \code
           \tt {\span {id="color-blue"} {Blue(#0000ff)}},
           \tt {\span {id="color-darkBlue"} {dark blue(#000080)}} and
           \tt {\span {id="color-cyan"} {cyan(#00ffff)}}.
       \endcode

       ...which is rendered as:

           \tt {\span {id="color-blue"} {Blue(#0000ff)}},
           \tt {\span {id="color-darkBlue"} {dark blue(#000080)}} and
           \tt {\span {id="color-cyan"} {cyan(#00ffff)}}.

    \target unicode-command
    \section1 \\unicode

    The \\unicode command allows you to insert an arbitrary Unicode
    character in the document.

    The command takes an argument specifying the character as an
    integer. By default, base 10 is assumed, unless a '0x' or '0'
    prefix is specified (for base 16 and 8, respectively). For
    example:

           \code
                O G\unicode{0xEA}nio e as Rosas

                \unicode 0xC0 table en famille avec 15 \unicode 0x20AC par jour

                \unicode 0x3A3 \e{a}\sub{\e{i}}
           \endcode

    QDoc renders this as:

           \quotation
                O G\unicode{0xEA}nio e as Rosas

                \unicode 0xC0 table en famille avec 15 \unicode 0x20AC par jour

                \unicode 0x3A3 \e{a}\sub{\e{i}}
           \endquotation
*/
