hello

I have edit a Qt application using QGraphicsView / QGraphicScene and it's consume a lot of cpu (60%).

my classes are a custom QGraphicsView / QGraphicScene and Reimplemented
Qt Code: 
  1. QGraphicsView::drawforeground(QPainter* ptPainter, const QRectF& tRectToDraw)
To copy to clipboard, switch view to plain text mode 
and
Qt Code: 
  1. QGraphicsView::drawbackground(QPainter* ptPainter, const QRectF& tRectToDraw)
To copy to clipboard, switch view to plain text mode 
used for drawing some statics items.

and i think thats methods causes the big consume of cpu.
my question is how can i optimise my application and reducing cpu consume.

thanx in advance.
