QGraphicsView render add processbar
I want add a processbar in the QGraphicsView render(),but it is not virtual, who can tell me how to do.
what is a processbar? Or do you mean QProgressBar?
How do you want to appear it exactly.
Basically you do not need to reimplement the render() method but rather it's paint methods:
But better would be to add a QGraphicsItem into the view.
Think you, I mean QProgressBar.
Because of I add a lot of QGraphicsItem int QGraphicsScene, and I want to use render() to export them in a image, it will spend a lot of time.
I read assistan again, I will try to reimplement drawItems() to solve this problem.
