TransitionWindow is not tested or qualified on NSWindows. It may
happen to work in certain instances, but there's currently no
intention that it should.
So is there a list of the safe and unsafe functions for such
WindowRefs? (Just the safe list would be fine, since I guess
everything else should be considered unsafe).
Do you mean, safe and unsafe APIs other than TransitionWindow?
Yes
I don't have such a list myself. It's possible that someone else in
AppKit-land may have one, but I'm not sure anyone has gone through
and exhaustively tested the Window Manager on AppKit-generated
windows. In general, it's best to use the API the corresponds to
the "true nature" of the window; if it's really an AppKit window,
use NSWindow APIs, and if it's really a Carbon window, use Window
Manager APIs.
OK, so to put it another way. What is [NSWindow windowRef] really
intended for. The documentation is a bit vague and misleading:
****
Discussion
This method can be used to create a WindowRef for a window containing
a Carbon control. Subsequent calls to this method return the existing
WindowRef.
For more information see MacWindows.h.
****
Is it really only intended to be used on NSWindows that were created
using [NSWindow initWithWindowRef:], and as such are 'real' Carbon
windows with an NSWindow wrapper.
As far as I know, it is not possible to have a genuine Cocoa NSWindow
with 'a Carbon control'.
