I'm trying to create a view that has a custom shape, so that mouse
events get "forwarded" to views that are behind this custom view. (I
say "forwarded" in quotes, because if events are outside this weird-
shaped view, events won't even get passed through this view.)
Specifically, I have an NSMovieView in my interface, with an
NSCustomView that covers the whole window. However, I'd still like
users to be able to directly use the NSMovieView controller -- they
should be able to drag the slider to a position, click the play/pause
button, and use the step forward and step back buttons. I don't want
to programatically forward these events, though, so I figured that I
could create a custom view that has a hole where the NSMovieView's
controller is. That way, mouse events in that area would be directly
passed to the NSMovieView, without any intervention.
The FunkyOverlayWindow sample project from Apple's developer site
( http://developer.apple.com/samplecode/FunkyOverlayWindow/
FunkyOverlayWindow.html ), seems to provide a way to do this for
windows. Specifically, a window is created containing a single
NSView that covers the whole view of the window. The window is set
to be non-opaque, and then you can color the NSView with various
colors so that it becomes a custom window. You can also use a
clearColor to create a hole in the view, which effectively creates a
hole in the window -- you can click in the hole, and the window
behind the overlay window will be brought to the front instead.
It seems to accomplish this by overriding the -(void)drawRect:(NSRect)
rect method of an NSView. However, if I do this for the custom view
that sits atop my NSMovieView, it seems to instead paint black over
the parts that I specified to be clear, and mouse events are not
passed to the NSMovieView -- they are still intercepted by my custom
view.
Any suggestions?
