Translucent window background in 4.3.2 - possible?

[ntp]

Do you only want part of the windows transparent? If so, then I think you'll have to go into Qt source code and make the changes yourself.

If you want the whole app to have some sort of transparency, you can use QWidget::setWindowOpacity(qreal level);

The first case: I want to draw a custom shadow with ranging alpha value on the sides of my window, while other parts staying opaque.

Ok, thanks, perhaps I'll try to search on how QA_TranslucentBackground is implemented in 4.5.x...
