Problem resizing a QDockWidget when QMainWindow has WA_TranslucentBackground attribute

aidaqt

Hi,

When I use this two properties:

setWindowFlags(Qt::FramelessWindowHint);
setAttribute(Qt::WA_TranslucentBackground);

then, in my QMainWindow, if I want to resize with the mouse a QDockWidget, the QDockWidgets stays bad painted, and then if I focus off of the QMainWindow, the QDockWidget gets painted well. What do I need to repaint fine the window and where?

Thanks in advance!

QT 4.8.0, Windows 7

I've found some related bug reports. Is there any workaround for this bug? Or it isnt a bug?

Hi,

You should link the bug reports you have found so other users might help you.

You should also consider trying with Qt 4.8.5
