Custom Paint Device?

  • I'm wondering how to write a custom paint device, there appears to be no examples/tutorials on this.

    I have tried to extend both QCustomRasterPaintDevice and QPaintDevice. How ever I want to the engine to be of the type QRasterPaintEngine.

    The reason I want to do this is so I can attempt to paint to a massive raster device, more than I normally could create with QImage using file mapping.

    Can any one give me some advice on this?
