I guess this is OK in the sense that originally the view did say
that it didn't need any space. Aside from resizing the window, is

I've hunted through the headers, but nothing is jumping out at me?
I don't think there's any way to let the HIToolbox know that your
size constraints have changed, but one trick you could use would be

DisableScreenUpdates/EnableScreenUpdates so that toolbar appears to
Yes, that did the trick nicely. Thanks! :)
You could also file a bug requesting a better way to do this. In

which the toolbar could handle (but doesn't currently) and if we
implemented that, then you could send the event from your view.
Hmm... yes, that was indeed what I was looking for. I've filed the
