The QRasterPaintEngine class enables hardware acceleration of painting operations in Qt for Embedded Linux.
\inmodule QtGui
Note that this functionality is only available in Qt for Embedded Linux.
In Qt for Embedded Linux, painting is a pure software implementation. But starting with Qt 4.2, it is possible to add an accelerated graphics driver to take advantage of available hardware resources.
Hardware acceleration is accomplished by creating a custom screen driver, accelerating the copying from memory to the screen, and implementing a custom paint engine accelerating the various painting operations. Then a custom paint device and a custom window surface must be implemented to make Qt for Embedded Linux aware of the accelerated driver.
