There are applications for which this isn't good enough but I guess there must

I'm toying around with a click-and-hold-opens-the-contextmenu feature (ported
from Mac where this makes a bit more sense), based on the TapAndHold gesture.
looks like that event is good demonstration why event tracking isn't 100%
reliable. When I activate processing of that gesture on a QToolButton with a
menu, it finishes (triggers) even when I am not holding any mouse button. The
event filter in which I implement this feature also catches MouseRelease and
MouseMove events (to turn off the gesture processing); I'm not getting those
either when the QToolButton's menu is open.
IOW, when I click once on the button to open its menu, the contextmenu is
too after the expected delay. The only reliable way I found to prevent this is
to check if the mouse button is still pressed when the TapAndHold gesture
to be finished.
