NAME

       QPaintEvent - Event parameters for paint events

SYNOPSIS

       #include <qevent.h>

       Inherits QEvent.

   Public Members
       QPaintEvent ( const QRegion & paintRegion, bool erased = TRUE )
       QPaintEvent ( const QRect & paintRect, bool erased = TRUE )
       const QRect & rect () const
       const QRegion & region () const
       bool erased () const

DESCRIPTION

       The QPaintEvent class contains event parameters for paint events.

       Paint events are sent to widgets that need to update themselves, for instance when part of a widget is exposed because a covering widget is
       moved.

       The event contains a region() that needs to be updated, and a rect() that is the bounding rectangle of that region. Both are provided
       because many widgets can't make much use of region(), and rect() can be much faster than region().boundingRect(). Painting is clipped to
       region() during processing of a paint event.

       The erased() function returns TRUE if the region() has been cleared to the widget's background (see QWidget::backgroundMode()), and FALSE
       if the region's contents are arbitrary.

       See also QPainter, QWidget::update(), QWidget::repaint(), QWidget::paintEvent(), QWidget::backgroundMode, QRegion, and Event Classes.

MEMBER FUNCTION DOCUMENTATION

QPaintEvent::QPaintEvent ( const QRegion & paintRegion, bool erased = TRUE )
       Constructs a paint event object with the region that should be updated. The region is given by paintRegion. If erased is TRUE the region
       will be cleared before repainting.

QPaintEvent::QPaintEvent ( const QRect & paintRect, bool erased = TRUE )
       Constructs a paint event object with the rectangle that should be updated. The region is given by paintRect. If erased is TRUE the region
       will be cleared before repainting.

bool QPaintEvent::erased () const
       Returns TRUE if the paint event region (or rectangle) has been erased with the widget's background; otherwise returns FALSE.

const QRect &; QPaintEvent::rect () const
       Returns the rectangle that should be updated.

       See also region() and QPainter::setClipRect().

       Examples:

const QRegion &; QPaintEvent::region () const
       Returns the region that should be updated.

       See also rect() and QPainter::setClipRegion().

NAME

       QResizeEvent - Event parameters for resize events

SYNOPSIS

       #include <qevent.h>

       Inherits QEvent.

   Public Members
       QResizeEvent ( const QSize & size, const QSize & oldSize )
       const QSize & size () const
       const QSize & oldSize () const

DESCRIPTION

       The QResizeEvent class contains event parameters for resize events.

       Resize events are sent to widgets that have been resized.

       The event handler QWidget::resizeEvent() receives resize events.

       See also QWidget::size, QWidget::geometry, and Event Classes.

MEMBER FUNCTION DOCUMENTATION

QResizeEvent::QResizeEvent ( const QSize & size, const QSize & oldSize )
       Constructs a resize event with the new and old widget sizes, size and oldSize respectively.

const QSize &; QResizeEvent::oldSize () const
       Returns the old size of the widget.

const QSize &; QResizeEvent::size () const
       Returns the new size of the widget, which is the same as QWidget::size().
