See the following page for more information about this: 
 
http://doc.trolltech.com/4.1/qwidget.html#transparency-and-double-buffering 
 
Basically, in Qt 4.1, you need to call setAutoFillBackground(True) 
to be able to customize the background colour of standard widgets 
like QFrame and subclasses that don't provide their own 
implementation of paintEvent(). 
 
However, you should be able to set the background color in a parent 
widget and, even if the parent doesn't display a background, any 
children that do should inherit that from the parent.
