+
+
+The TQPaintEvent class contains event parameters for paint events.
+<p>
+<p> 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.
+<p> The event contains a <a href="#region">region</a>() that needs to be updated, and a
+<a href="#rect">rect</a>() 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.
+<p> The <a href="#erased">erased</a>() function returns TRUE if the region() has been
+cleared to the widget's background (see
+<a href="tqwidget.html#backgroundMode">TQWidget::backgroundMode</a>()), and FALSE if the region's contents are
+arbitrary.
+<p> <p>See also <a href="tqpainter.html">TQPainter</a>, <a href="tqwidget.html#update">TQWidget::update</a>(), <a href="tqwidget.html#repaint">TQWidget::repaint</a>(), <a href="tqwidget.html#paintEvent">TQWidget::paintEvent</a>(), <a href="tqwidget.html#backgroundMode-prop">TQWidget::backgroundMode</a>, <a href="ntqregion.html">TQRegion</a>, and <a href="events.html">Event Classes</a>.

+</h3>
+
+<p> Constructs a paint event object with the region that should be
+updated. The region is given by <em>paintRegion</em>. If <em>erased</em> is
+TRUE the region will be cleared before repainting.
+
+<h3 class=fn><a name="TQPaintEvent-2"></a>TQPaintEvent::TQPaintEvent ( const&nbsp;<a href="ntqrect.html">TQRect</a>&nbsp;&amp;&nbsp;paintRect, bool&nbsp;erased = TRUE )
+</h3>
+
+<p> Constructs a paint event object with the rectangle that should be
+updated. The region is also given by <em>paintRect</em>. If <em>erased</em> is
+TRUE the region will be cleared before repainting.
+
+<h3 class=fn><a name="TQPaintEvent-3"></a>TQPaintEvent::TQPaintEvent ( const&nbsp;<a href="ntqregion.html">TQRegion</a>&nbsp;&amp;&nbsp;paintRegion, const&nbsp;<a href="ntqrect.html">TQRect</a>&nbsp;&amp;&nbsp;paintRect, bool&nbsp;erased = TRUE )
+</h3>
+
+<p> Constructs a paint event object with the rectangle <em>paintRect</em>
+that should be updated. The region is given by <em>paintRegion</em>. If
+<em>erased</em> is TRUE the region will be cleared before repainting.
+
+<h3 class=fn>bool <a name="erased"></a>TQPaintEvent::erased () const
+</h3>
+
+<p> Returns TRUE if the paint event region (or rectangle) has been
+erased with the widget's background; otherwise returns FALSE.
+
+<h3 class=fn>const&nbsp;<a href="ntqrect.html">TQRect</a>&nbsp;&amp; <a name="rect"></a>TQPaintEvent::rect () const
+</h3>
+
+<p> Returns the rectangle that should be updated.
