[Interest] Semi transparent background for contextual menu

[Etienne Sandré-Chardonnal]

Hi,

That's because a context menu is a system level window, not a widget.
And what you call focus is in fact not focus, but active window. See
QApplication::activeWindow

You create such a window by creating a QWidget with no parent and a
WindowFlag:

QWidget(0, Qt::Popup);
