QWidget update calls
-
Hello All
I am experiencing a problem of extra paint requests inside q3scrollview::viewportpaintevent().
I am doing simple thing of switching my application with another windows application.
I suppose windows keeps paint buffers and hence should not call the paint event of my widget class.Is this correct understanding or something is missing from this ?

Hi and welcome to devnet,
I can't say whether you're right or wrong, I can only encourage your to update your code to use QScrollView. The Qt3Support module was meant to help the transition to Qt 4.

Thanks.
I was also thinking of migrating to qscrollview.
But in my context I think this is a generic behaviour. Means, I have a standalone application which just displays a widget inside a qapplication. I have put in debug prints in the paintevent.
I saw that this is hit each time this application is focussed out and in.myScroll* scroll = new myScroll(NULL,0 );
scroll->show();
return application.exec();Regards

Because a focus change will modify how a widget is painted e.g. dimmer color, slightly greyed etc.
