DESCRIPTION

       The QPaintEvent class contains event parameters for paint
       events.

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

       The event handler QWidget::paintEvent() receives paint
       events.

       See also QPainter, QWidget::update() and
       QWidget::repaint().

       Examples: qtimage/qtimage.cpp grapher/grapher.cpp
       drawlines/connect.cpp xform/xform.cpp
       drawdemo/drawdemo.cpp progress/progress.cpp qmag/qmag.cpp
       splitter/splitter.cpp desktop/desktop.cpp
       trivial/trivial.cpp picture/picture.cpp


MEMBER FUNCTION DOCUMENTATION


QPaintEvent::QPaintEvent ( const QRect & paintRect, bool

       erased=TRUE = TRUE )

       should be updated.


QPaintEvent::QPaintEvent ( const QRegion & paintRegion, bool

       erased=TRUE = TRUE )
       Constructs a paint event object with the region that
       should be updated.


bool QPaintEvent::erased () const

       Returns whether the paint event region (or rectangle) has
       been erased with the widget's background.


const QRect & QPaintEvent::rect () const

       Returns the rectangle that should be updated.


       Examples: qtimage/qtimage.cpp grapher/grapher.cpp
       progress/progress.cpp splitter/splitter.cpp
       trivial/trivial.cpp


const QRegion & QPaintEvent::region () const

       Returns the region that should be updated.
