Detailed Description

QRasterWindow is a QWindow with a raster-based, non-OpenGL surface. On top of the functionality offered by QWindow , QRasterWindow adds a virtual paintEvent() function and the possibility to open a QPainter 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 QOpenGLWindow instead.

Internally the class is thin wrapper for QWindow and QBackingStore and is very similar to the Raster Window Example that uses these classes directly.
