## Detailed Description

The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.

Qt contains a set of QStyle subclasses that emulate the styles of the different platforms supported by Qt (QWindowsStyle, QMacStyle, QMotifStyle, etc.). By default, these styles are built into the QtGui library. Styles can also be made available as plugins.

Qt's built-in widgets use QStyle to perform nearly all of their drawing, ensuring that they look exactly like the equivalent native widgets. The diagram below shows a QComboBox in eight different styles.

Topics:

- Setting a Style
- Developing Style-Aware Custom Widgets
- Creating a Custom Style
- Using a Custom Style
- Right-to-Left Desktops

### Setting a Style

The style of the entire application can be set using QApplication::setStyle(). It can also be specified by the user of the application, using the `-style` command-line option:

        ./myapplication -style motif

If no style is specified, Qt will choose the most appropriate style for the user's platform or desktop environment.

A style can also be set on an individual widget using QWidget::setStyle().

### Developing Style-Aware Custom Widgets

If you are developing custom widgets and want them to look good on all platforms, you can use QStyle functions to perform parts of the widget drawing, such as drawItem(), drawPrimitive(), drawControl(), and drawComplexControl().

Most QStyle draw functions take four arguments:

- an enum value specifying which graphical element to draw
- a QStyleOption specifying how and where to render that element
- a QPainter that should be used to draw the element
- a QWidget on which the drawing is performed (optional)

For example, if you want to draw a focus rectangle on your widget, you can write:

        void MyWidget::paintEvent(QPaintEvent * /* event */)
        {
            QPainter painter(this);

            QStyleOptionFocusRect option;
            option.initFrom(this);
            option.backgroundColor = palette().color(QPalette::Background);

            style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);
        }

QStyle gets all the information it needs to render the graphical element from QStyleOption. The widget is passed as the last argument in case the style needs it to perform special effects (such as animated default buttons on Mac OS X), but it isn't mandatory. In fact, you can use QStyle to draw on any paint device, not just widgets, by setting the QPainter properly.

QStyleOption has various subclasses for the various types of graphical elements that can be drawn. For example, PE_FrameFocusRect expects a QStyleOptionFocusRect argument. This is documented for each enum value.

To ensure that drawing operations are as fast as possible, QStyleOption and its subclasses have public data members. See the QStyleOption class documentation for details on how to use it.

For convenience, Qt provides the QStylePainter class, which combines a QStyle, a QPainter, and a QWidget. This makes it possible to write

            QStylePainter painter(this);
            ...
            painter.drawPrimitive(QStyle::PE_FrameFocusRect, option);

instead of

            QPainter painter(this);
            ...
            style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);

### Creating a Custom Style

If you want to design a custom look and feel for your application, the first step is to pick one of the base styles provided with Qt to build your custom style from. The choice will depend on which existing style resembles your style the most.

Depending on which parts of the base style you want to change, you must reimplement the functions that are used to draw those parts of the interface. To illustrate this, we will modify the look of the spin box arrows drawn by QWindowsStyle. The arrows are primitive elements that are drawn by the drawPrimitive() function, so we need to reimplement that function. We need the following class declaration:

        class CustomStyle : public QWindowsStyle
        {
            Q_OBJECT

        public:
            CustomStyle() {}
            ~CustomStyle() {}

            void drawPrimitive(PrimitiveElement element, const QStyleOption *option,
                               QPainter *painter, const QWidget *widget) const;
        };

The PE_IndicatorSpinUp and PE_IndicatorSpinDown primitive elements are used by QSpinBox to draw its up and down arrows. Here's how to reimplement drawPrimitive() to draw them differently:

        void CustomStyle::drawPrimitive(PrimitiveElement element, const QStyleOption *option,
                                        QPainter *painter, const QWidget *widget) const
        {
            if (element == PE_IndicatorSpinUp || element == PE_IndicatorSpinDown) {
                QPointArray points(3);
                int x = option->rect.x();
                int y = option->rect.y();
                int w = option->rect.width() / 2;
                int h = option->rect.height() / 2;
                x += (option->rect.width() - w) / 2;
                y += (option->rect.height() - h) / 2;

                if (element == PE_IndicatorSpinUp) {
                    points[0] = QPoint(x, y + h);
                    points[1] = QPoint(x + w, y + h);
                    points[2] = QPoint(x + w / 2, y);
                } else { // PE_SpinBoxDown
                    points[0] = QPoint(x, y);
                    points[1] = QPoint(x + w, y);
                    points[2] = QPoint(x + w / 2, y + h);
                }

                if (option->state & Style_Enabled) {
                    painter->setPen(option->palette.mid().color());
                    painter->setBrush(option->palette.buttonText());
                } else {
                    painter->setPen(option->palette.buttonText().color());
                    painter->setBrush(option->palette.mid());
                }
                painter->drawPolygon(points);
            } else {
                QWindowsStyle::drawPrimitive(element, option, painter, widget);
            }
        }

Notice that we don't use the `widget` argument, except to pass it on to QWindowStyle::drawPrimitive(). As mentioned earlier, the information about what is to be drawn and how it should be drawn is specified by a QStyleOption object, so there is no need to ask the widget.

If you need to use the `widget` argument to obtain additional information, be careful to ensure that it isn't 0 and that it is of the correct type before using it. For example:

        QSpinBox *spinBox = qobject_cast<QSpinBox *>(widget);
        if (spinBox) {
            ...
        }

When implementing a custom style, you cannot assume that the widget is a QSpinBox just because the enum value is called PE_IndicatorSpinUp or PE_IndicatorSpinUp.

The documentation for the Styles example covers this topic in more detail.

### Using a Custom Style

There are several ways of using a custom style in a Qt application. The simplest way is call the QApplication::setStyle() static function before creating the QApplication object:

        #include <QtGui>

        #include "customstyle.h"

        int main(int argc, char *argv[])
        {
            QApplication::setStyle(new CustomStyle);
            QApplication app(argc, argv);
            QSpinBox spinBox;
            spinBox.show();
            return app.exec();
        }

You can call QApplication::setStyle() at any time, but by calling it before the constructor, you ensure that the user's preference, set using the `-style` command-line option, is respected.

You may want to make your style available for use in other applications, some of which may not be yours and are not available for you to recompile. The Qt Plugin system makes it possible to create styles as plugins. Styles created as plugins are loaded as shared objects at runtime by Qt itself. Please refer to the Qt Plugin documentation for more information on how to go about creating a style plugin.

Compile your plugin and put it into `$QTDIR/plugins/styles`. We now have a pluggable style that Qt can load automatically. To use your new style with existing applications, simply start the application with the following argument:

        ./myapplication -style custom

The application will use the look and feel from the custom style you implemented.

### Right-to-Left Desktops

Languages written from right to left (such as Arabic and Hebrew) usually also mirror the whole layout of widgets, and require the light to come from the screen's top-right corner instead of top-left.

If you create a custom style, you should take special care when drawing asymmetric elements to make sure that they also look correct in a mirrored layout. An easy way to test your styles is to run applications with the `-reverse` command-line option or to call QApplication::setLayoutDirection() in your `main()` function.

Here are some things to keep in mind when making a style work well in a right-to-left environment:

- subControlRect() and subElementRect() return rectangles in screen coordinates
- QStyleOption::direction indicates in which direction the item should be drawn in
- If a style is not right-to-left aware it will display items as if it were left-to-right
- visualRect(), visualPos(), and visualAlignment() are helpful functions that will translate from logical to screen representations.
- alignedRect() will return a logical rect aligned for the current direction

### QPixmap QStyle::generatedIconPixmap ( QIcon::Mode iconMode, const QPixmap & pixmap, const QStyleOption * option ) const `[pure virtual]`

Returns a pixmap styled to conform to iconMode description out of pixmap, and taking into account the palette specified by option.

The option can pass extra information, but it must contain a palette.

Not all types of pixmaps will change from their input in which case the result will simply be the pixmap passed in.

### SubControl QStyle::hitTestComplexControl ( ComplexControl control, const QStyleOptionComplex * option, const QPoint & pos, const QWidget * widget = 0 ) const `[pure virtual]`

Returns the SubControl in the ComplexControl control with the style options specified by option at the point pos. The option argument is a pointer to a QStyleOptionComplex structure or one of its subclasses. The structure can be cast to the appropriate type based on the value of control. See drawComplexControl() for details.

The widget argument is optional and can contain additional information for the functions.

Note that pos is expressed in screen coordinates.

See also drawComplexControl(), ComplexControl, SubControl, subControlRect(), and QStyleOptionComplex.

### QRect QStyle::itemPixmapRect ( const QRect & rect, int alignment, const QPixmap & pixmap ) const `[virtual]`

Returns the appropriate area within rectangle rect in which to draw the pixmap with alignment defined in alignment.

### QRect QStyle::itemTextRect ( const QFontMetrics & metrics, const QRect & rect, int alignment, bool enabled, const QString & text ) const `[virtual]`

Returns the appropriate area (see below) within rectangle rect in which to draw text using the font metrics metrics.

The text is aligned in accordance with alignment. The enabled bool indicates whether or not the item is enabled.

If rect is larger than the area needed to render the text the rectangle that is returned will be offset within rect in accordance with the alignment alignment. For example, if alignment is Qt::AlignCenter, the returned rectangle will be centered within rect. If rect is smaller than the area needed, the rectangle that is returned will be larger than rect (the smallest rectangle large enough to render the text).

See also Qt::Alignment.

### int QStyle::pixelMetric ( PixelMetric metric, const QStyleOption * option = 0, const QWidget * widget = 0 ) const `[pure virtual]`

Returns the pixel metric for the given metric. The option and widget can be used for calculating the metric. The option can be cast to the appropriate type based on the value of metric. Note that option may be zero even for PixelMetrics that can make use of option. See the table below for the appropriate option casts:

PixelMetric | Option Cast
--- | ---
PM_SliderControlThickness | QStyleOptionSlider
PM_SliderLength | QStyleOptionSlider
PM_SliderTickmarkOffset | QStyleOptionSlider
PM_SliderSpaceAvailable | QStyleOptionSlider
PM_ScrollBarExtent | QStyleOptionSlider
PM_TabBarTabOverlap | QStyleOptionTab
PM_TabBarTabHSpace | QStyleOptionTab
PM_TabBarTabVSpace | QStyleOptionTab
PM_TabBarBaseHeight | QStyleOptionTab
PM_TabBarBaseOverlap | QStyleOptionTab

In general, the widget argument is not used.

### void QStyle::polish ( QWidget * widget ) `[virtual]`

Initializes the appearance of widget.

This function is called for every widget at some point after it has been fully created but just before it is shown for the very first time.

Reasonable actions in this function might be to call QWidget::setBackgroundMode() for the widget. An example of highly unreasonable use would be setting the geometry! Reimplementing this function gives you a back-door through which you can change the appearance of a widget. With Qt 4.0's style engine you will rarely need to write your own polish(); instead reimplement drawItem(), drawPrimitive(), etc.

The QWidget::inherits() function may provide enough information to allow class-specific customizations. But be careful not to hard-code things too much because new QStyle subclasses are expected to work reasonably with all current and future widgets.

See also unpolish().

### void QStyle::polish ( QApplication * app ) `[virtual]`

This is an overloaded member function, provided for convenience.

Late initialization of the QApplication object app.

See also unpolish().

### void QStyle::polish ( QPalette & pal ) `[virtual]`

This is an overloaded member function, provided for convenience.

The style may have certain requirements for color palettes. In this function it has the chance to change the palette pal according to these requirements.

See also QPalette and QApplication::setPalette().

### QSize QStyle::sizeFromContents ( ContentsType type, const QStyleOption * option, const QSize & contentsSize, const QWidget * widget = 0 ) const `[pure virtual]`

Returns the size of styled object described in option based on the contents size contentsSize.

The option argument is a pointer to a QStyleOption or one of its subclasses. The option can be cast to the appropriate type based on the value of type. The widget widget is optional argument and can contain extra information used for calculating the size. See the table below for the appropriate option usage:

ContentsType | Option Cast
--- | ---
CT_PushButton | QStyleOptionButton
CT_CheckBox | QStyleOptionButton
CT_RadioButton | QStyleOptionButton
CT_ToolButton | QStyleOptionToolButton
CT_ComboBox | QStyleOptionComboBox
CT_Splitter | QStyleOption

### int QStyle::sliderPositionFromValue ( int min, int max, int logicalValue, int span, bool upsideDown = false ) `[static]`

Converts logicalValue to a pixel position. min maps to 0, max maps to span and other values are distributed evenly in-between.

This function can handle the entire integer range without overflow, providing span is less than 4096.

By default, this function assumes that the maximum value is on the right for horizontal items and on the bottom for vertical items. Set upsideDown to true to reverse this behavior.

See also sliderValueFromPosition().

### int QStyle::sliderValueFromPosition ( int min, int max, int pos, int span, bool upsideDown = false ) `[static]`

Converts the pixel position pos to a value. 0 maps to min, span maps to max and other values are distributed evenly in-between.

This function can handle the entire integer range without overflow.

By default, this function assumes that the maximum value is on the right for horizontal items and on the bottom for vertical items. Set upsideDown to true to reverse this behavior.

See also sliderPositionFromValue().

### QIcon QStyle::standardIcon ( StandardPixmap standardIcon, const QStyleOption * option = 0, const QWidget * widget = 0 ) const

Returns an icon for standardIcon.

The option argument can be used to pass extra information required when determining the icon.

The widget argument is optional and may contain a widget that may aid determining the icon.

Warning: Because of binary compatibility constraints, this function is not virtual. If you want to provide your own icons in a QStyle subclass, add a slot called standardIconImplementation() to you subclass. The standardIcon() function will dynamically detect the slot and call it.

This function was introduced in Qt 4.1.

See also standardIconImplementation() and standardPixmap().

### QIcon QStyle::standardIconImplementation ( StandardPixmap standardIcon, const QStyleOption * option = 0, const QWidget * widget = 0 ) const `[protected slot]`

Returns an icon for standardIcon.

The option argument contains extra information required when determining the icon. The widget argument is optional and may contain a widget that may aid determining the icon.

The default implementation simply calls standardPixmap(standardIcon, option, widget).

Warning: Because of binary compatibility constraints, the standardIcon() function, introduced in Qt 4.1, isn't virtual. If you want to provide your own icons in a QStyle subclass, add a slot called standardIconImplementation() to your subclass. The standardIcon() function will dynamically detect the slot and call it.

This function was introduced in Qt 4.1.
