Comment (by ttcoder):
Proposed Solutions:
Not sure how feasible it is, but it seems to me SetEventMask() should
behave more like SetMouseEventMask() (I might be wrong but I recall that
the latter re-routes mouse events instead of adding a ''second'' event
snooping copy); maybe SetEventMask(keyboard..) should do the same: stop
sending the keyboard events to the window and re-route them to the view...
And when applicable, the view would "bounce up" those messages it cannot
handle, like Command-Q, Command-W ..etc messages, for the window to
eventually process them as it should in its own hooks.
Another solution would be to keep the dual-BMessage aspect but fix the
special treatment of Command-xyz messages so that it discriminates between
the first and second instance of the message: the first instance of e.g.
Alt-V would land in the BWindow hooks where it would trigger a B_PASTE
(only once!), and the second instance of the Alt-V message would land in
the BView KeyDown() hook where it would have a chance of being properly
ignored, instead of triggering a second B_PASTE.
