[Qt-interest] updating QGraphicsScene

[Deepak Chandran]

Where do I call the update? The QGraphicsView is doing the scrolling -- do I need to create a new class that inherits from QGraphicsView and then call the update() in the scroll event of that new class? I suppose that might work, although I though there might be a better solution.

QGraphicsScene


I need to draw a grid on the background of a QGraphicsScene. I can draw the 
grid by overwriting the drawBackground(...) method. But the scene does not 
update when I scroll up and down. Should I use the drawBackground() method in 
QGraphicsView instead? Or is there any other way to perform the 
update?
