Simulate QMenu hover on a QAction?

[Matic Kukovec]

Hello again,

For anyone looking at this thread, the problem is that the widgets added to the QWidgetAction with .setDefaultWidget consume the mouseMoveEvent, which needs to be ignored.
The solution is to enable mouse tracking on all widgets in the added to the QWidgetAction with .setMouseTracking(True) and then overriding the mouseMoveEvent method and ignoring the event in every widget, like so:
def mouseMoveEvent(self, event):
    event.ignore()

Thanks for the hints
Matic

I just rechecked, and yes, I'm not using a QAction, but a QWidgetAction on which I first set a default widget with setDefaultWidget,
which is a groupbox with a few labels with text/images, then add a menu with setMenu.

Uhm. I see a QComboBox that shows what appears to be a QMenu instead of the standard popup, so, yes, that could be the issue, especially if you're overriding the popup behavior on mouse press.
I suggest you to share a minimal reproducible example so that we could better understand what's going on.
