[UFO-devel] mouse press events and ufo::UMenuItem

[Andreas B. <b_...@gm...>]

Hi
the attached fix makes sure that MousePress events are consumed when clicking 
on a menu item.
Without this patch the event may get propagated back to other widgets and 
eventually causing a call to closeMenuPopups() that hides the menu. The click 
on the menu item is still correctly processed, but the following mouse press 
event is then not eaten by the menu item anymore (because 
w_under_mouse->contains(e->getLocation()) is false then).

I am not fully sure if this problem appears in official libufo cvs, too, but I 
think this patch should not have any evil side effects (actually the menu 
item _should_ consume the event, as it waits for the corresponding release 
event then).
You can test whether the problem appears in official libufo by doing:
Click on a menu item and hold the button. If the menu gets hidden, then the 
bug does appear. If the menu gets hidden only after releasing the button, 
then not.

(It certainly does happen for me, but as said before I am using a heavily 
modified event dispatch code that also works for layered panes)
