I am using a QTMovieView to play back a movie. I wish for there to be no
chance of user interaction with the movie: pure playback. The behavior is
window shows, movie auto-plays (QTMovieView takes up the whole of the window
content area), when movie is done the window closes.
I noticed if I clicked on the movie that it would stop the playback. I didn't
want this. So I subclassed QTMovieView and added empty overrides for:
-mouseDown:
-rightMouseDown:
-otherMouseDown:
-mouseUp:
-rightMouseUp:
-otherMouseUp:
-scrollWheel:
The methods are totally stubbed out, they are empty and do nothing. This does
seem to stop any sort of user interaction. FWIW, I have also set the view to
be not editable, disabled, no playback controls.
But I noticed an interesting thing.
If I right-click, there's no contextual playback menu displayed. But if I
control-(left) click, the playback menu is displayed.
How is this happening? How is it that I have stubbed out all of the various
mouse methods yet a control-click gets through? And how can I get it to stop?
Answering my own question.
I added an override for -(NSMenu*)menuForEvent:(NSEvent*)theEvent;, just
stubbing it out, doing nothing, returning nil.
It works out fine and seems to solve my problem.
As well, are there any other subtle user-interaction approaches that I may
need to add to my stub-out list?
Still, I'd be curious if there might be any further subtle behaviors I need
to override/stub-out for QTMovieView so that it's purely watch only.
Thanx.
