<P>
<p>The <a href="QRegion.html#QRegion(com.trolltech.qt.core.QRect, com.trolltech.qt.gui.QRegion.RegionType)"><tt>QRegion</tt></a> class specifies a clip region for a painter.</p>
<p><a href="QRegion.html#QRegion(com.trolltech.qt.core.QRect, com.trolltech.qt.gui.QRegion.RegionType)"><tt>QRegion</tt></a> is used with QPainter::setClipRegion() to limit the paint area to what needs to be painted. There is also a QWidget::repaint() function that takes a <a href="QRegion.html#QRegion(com.trolltech.qt.core.QRect, com.trolltech.qt.gui.QRegion.RegionType)"><tt>QRegion</tt></a> parameter. <a href="QRegion.html#QRegion(com.trolltech.qt.core.QRect, com.trolltech.qt.gui.QRegion.RegionType)"><tt>QRegion</tt></a> is the best tool for reducing flicker.</p>
<p>A region can be created from a rectangle, an ellipse, a polygon or a bitmap. Complex regions may be created by combining simple regions using <a href="QRegion.html#united(com.trolltech.qt.gui.QRegion)"><tt>united</tt></a>, <a href="QRegion.html#intersected(com.trolltech.qt.gui.QRegion)"><tt>intersected</tt></a>, <a href="QRegion.html#subtracted(com.trolltech.qt.gui.QRegion)"><tt>subtracted</tt></a>, or <a href="QRegion.html#xored(com.trolltech.qt.gui.QRegion)"><tt>xored</tt></a> (exclusive or). You can move a region using <a href="QRegion.html#translate(int, int)"><tt>translate</tt></a>.</p>
<p>You can test whether a region <a href="QRegion.html#isEmpty()"><tt>isEmpty</tt></a> or if it <a href="QRegion.html#contains(com.trolltech.qt.core.QPoint)"><tt>contains</tt></a> a <a href="%2E%2E/core/QPoint.html"><tt>QPoint</tt></a> or <a href="%2E%2E/core/QRect.html"><tt>QRect</tt></a>. The bounding rectangle can be found with <a href="QRegion.html#boundingRect()"><tt>boundingRect</tt></a>.</p>
<p>The function <a href="QRegion.html#rects()"><tt>rects</tt></a> gives a decomposition of the region into rectangles.</p>
<p>Example of using complex regions:</p>
<pre> void MyWidget::paintEvent(QPaintEvent *)
{
QRegion r1(QRect(100, 100, 200, 80), <span class="comment">// r1: elliptic region</span>
QRegion::Ellipse);
QRegion r2(QRect(100, 120, 90, 30)); <span class="comment">// r2: rectangular region</span>
QRegion r3 = r1.intersected(r2); <span class="comment">// r3: intersection</span>
QPainter painter(this);
painter.setClipRegion(r3);
... <span class="comment">// paint clipped graphics</span>
}</pre>
<p><a href="QRegion.html#QRegion(com.trolltech.qt.core.QRect, com.trolltech.qt.gui.QRegion.RegionType)"><tt>QRegion</tt></a> is an implicitly shared class</tt>.</p>
<p><b>Warning:</b> Due to window system limitations, the whole coordinate space for a region is limited to the points between -32767 and 32767 on Windows 95/98/ME. You can circumvent this limitation by using a <a href="QPainterPath.html"><tt>QPainterPath</tt></a>.</p>
