- QLabel ( const QString & text, QWidget * parent, const char * name, Qt::WFlags f = 0 )
- QLabel ( QWidget * buddy, const QString & text, QWidget * parent = 0, const char * name = 0, Qt::WFlags f = 0 )
- void setAlignment ( int alignment )

- 60 public functions inherited from QWidget
- 8 public functions inherited from QObject

## Member Function Documentation

### QLabel::QLabel ( QWidget * parent, const char * name, Qt::WFlags f = 0 )

Constructs an empty label.

The parent, name and widget flag f, arguments are passed to the QFrame constructor.

See also setAlignment(), setFrameStyle(), and setIndent().

### QLabel::QLabel ( const QString & text, QWidget * parent, const char * name, Qt::WFlags f = 0 )

Constructs a label that displays the text, text.

The parent, name and widget flag f, arguments are passed to the QFrame constructor.

See also setText(), setAlignment(), setFrameStyle(), and setIndent().

### QLabel::QLabel ( QWidget * buddy, const QString & text, QWidget * parent = 0, const char * name = 0, Qt::WFlags f = 0 )

Constructs a label that displays the text text. The label has a buddy widget, buddy.

If the text contains an underlined letter (a letter preceded by an ampersand, &), and the text is in plain text format, when the user presses Alt+ the underlined letter, focus is passed to the buddy widget.

The parent, name and widget flag, f, arguments are passed to the QFrame constructor.

See also setText(), setBuddy(), setAlignment(), setFrameStyle(), and setIndent().

### void QLabel::setAlignment ( int alignment )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Use setAlignment(Qt::Alignment) instead.

If alignment specifies text flags as well, use setTextFormat() to set those.
