I have a document class which has a "dirty" flag. My output window (a QScrollView), checks the flag at intervals (using a QTimer). If the flag is set self.UpdateContents() is called.
In drawContents(), it checks the flag. If it is set it puts the output into a buffer pixmap, and uses painter.drawPixmap to put that to the QScrollView (over the entire thing if the dirty flag is set). The dirty flag is then reset.
I'm having problems where only part of the output window is getting overwritten using this procedure. It looks like Qt is doing some sort of clipping in drawContents(). This happens particularly with a popup menu which changes the program's output. When the popup closes, only the window beneath the popup is repainted. I can get round it much of the time by putting a app.eventLoop().processEvents(allevents, 100000) after the popup exec_loop().
Has anyone hit this problem before? Am I doing something stupid??
Now I need to work out how to get the random maybeTip tooltip exceptions I get occassionally...
Thanks
Jeremy
