Hi,
Here is a Scenario, A series of operations that I will call for painting,
QPainter p(this);
1). p.fillRect(0,0,320,240, RED_COLOR)
2) p.drawLine(0,0,100,100, BLUE_COLOR)
3) p.fillRect(0,0,320,240, YELLOW_COLOR)
Now I want that painter should not draw first FillRect Function. It should not draw line. It should only perform last operation.
Is there any way to achive this optimization in Qt.
Is this type of drawing/painting optimizations are supported by any library?
