I want to call TransitionWindowWithOptions on a NSWindow. I can get a WindowRef back from NSWindow without any problems, and the first time I call TransitionWindowWithOptions on it, it appears to work just fine. The second time I call TransitionWindowWithOptions on it with the same transition and action, nothing seems to happen (although the return status is noErr). I can call TransitionWindowWithOptions with a different transition/action and it appears to work the first time, but won't work again after that.

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.

Presumably Dave should file a bug report then, requesting a feature enhancement. It's a pity that while Apple has promoted Cocoa as the preferred OS X development API for five years there is still a stack of things that can not be done when using Cocoa but can be done if not using Cocoa.
OTOH, many of the modes supported by TransitionWindow look terrible in OS X. TransitionWindow was originally intended to let a developer mimic the "zoom" effect used by the Finder when new windows are opened. In OS 9 it was a perfect match. In OS X, TransitionWindow provides a very retro "zooming squares" effect, while the real Finder actually has a gorgeous scaling effect.

Nowadays it's been augmented with other transition types that look OK on OS X, but they still haven't revisited the original zoom effect yet. :| I have an open radar on this that's been idle for a long time (years?).
