<hr><h2><a name="details"></a>Detailed Description</h2>
The QPaintEvent class contains event parameters for paint events.
<p>
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.
<p>The event handler <a href="qwidget.html#e3d821">QWidget::paintEvent</a>() receives paint events.
<p>See also <a href="qpainter.html">QPainter</a>, <a href="qwidget.html#a66a88">QWidget::update</a>() and <a href="qwidget.html#7569b1">QWidget::repaint</a>().
