Hi,
Thank you for the answer. I made it work with your help, but I lost the
transparency of the popup.
If the widget has a parent, there is transparency, but I lost the
Qt::ActiveWindowFocusReason when I lost focus

I forgot, in order to detect when the window lost "focus" (ie is no
longer the active window), you need to catch QFocusEvent, and check if
reason() is Qt::ActiveWindowFocusReason
Cheers,
Etienne

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);

Hi,
I try to have a contextual menu with a semi-transparent
background. I didnt manage to to it with QMenu, so I decided
to use a custom widget.
I have no problem to have a widget with a semi-transparent
background, I just changed the alpha of the background color.
My problem is that I want this widget to behave like a
contextual menu, that is to say, I want it to be closed when
focus is lost. But this is lot as soon as I clic on a
children-widget of this menu. I don't know how to do.
