<h2 id="details">Detailed Description</h2>
<p><a href="qrasterwindow.html">QRasterWindow</a> is a convenience class for using <a href="qpainter.html">QPainter</a> on a <a href="qwindow.html">QWindow</a></p>
<p><a href="qrasterwindow.html">QRasterWindow</a> is a <a href="qwindow.html">QWindow</a> with a raster-based, non-OpenGL surface. On top of the functionality offered by <a href="qwindow.html">QWindow</a>, <a href="qrasterwindow.html">QRasterWindow</a> adds a virtual <a href="qpaintdevicewindow.html#paintEvent">paintEvent</a>() function and the possibility to open a <a href="qpainter.html">QPainter</a> on itself. The underlying paint engine will be the raster one, meaning that all drawing will happen on the CPU. For performing accelerated, OpenGL-based drawing, use <a href="qopenglwindow.html">QOpenGLWindow</a> instead.</p>
<p>Internally the class is thin wrapper for <a href="qwindow.html">QWindow</a> and <a href="qbackingstore.html">QBackingStore</a> and is very similar to the <a href="qtgui-rasterwindow-example.html">Raster Window Example</a> that uses these classes directly.</p>
