Hi all...
I am facing some problem while zooming in and out of a Graphicsscene.
I have a Graphics scene where I have 400 items placed ... when i change the poistion of the scroll bar while zooming, the zooming operation gets very slow...
in normal zooming and running my application is taking abt 14MB memory and abt 60% CPu while zooming.
But when i change the scroll bar position in the scene and zoom in... at some point the CPU usage gets to 99% and memory usage get to nearly 200 + MB...
I am not able to figure why this is happening... ne help ?:confused:
