Member Function Documentation

Q3Button::Q3Button ( QWidget * parent = 0, const char * name = 0, Qt::WindowFlags f = 0 )

Constructs a standard button called name with parent parent, using the widget flags f.

Q3Button::~Q3Button ()

void Q3Button::drawButton ( QPainter * painter ) [virtual protected]

Draws the button on the given painter. The default implementation does nothing.

This virtual function is reimplemented by subclasses to draw real buttons. At some point, these reimplementations should call drawButtonLabel().

See also drawButtonLabel() and paintEvent().

void Q3Button::drawButtonLabel ( QPainter * painter ) [virtual protected]

Draws the button text or pixmap on the given painter.

This virtual function is reimplemented by subclasses to draw real buttons. It is invoked by drawButton().

See also drawButton() and paintEvent().

void Q3Button::paintEvent ( QPaintEvent * event ) [virtual protected]

Reimplemented from QWidget::paintEvent().

Handles paint events, received in event, for buttons. Small and typically complex buttons are painted double-buffered to reduce flicker. The actually drawing is done in the virtual functions drawButton() and drawButtonLabel().

See also drawButton() and drawButtonLabel().
