[Glade-users] On_motion_notify_event

[PEYMAN ASKARI]

I don't forsee it being a problem unless performance is of utmost importance. I will probably come back to this later, and incorporate it into my program

DnD works unreliably with the hint mask set because the one motion notify
event is usually too close to the button press event to trigger the drag. 
I've not had a problem with an event backlog even on a slow platform, but
now I'm worried.  I suppose that one could block the event on drag-begin
and unblock it on drag-end.
