[Qt-interest] Problem with background-image + parent widget

[Tr3wory]

Hi!

I created my widget with the designer. I set an background image in
its stylesheet.
When I use this widget without parent (i.e. new window) everything works fine.

When I use with parent (with a StackedWidget, or just a plain
QWidget), it did not show the background image.

It is a bug, or a feature?
How can I change this?
