Cocoa in Carbon: mouse tracking

Cocoa in Carbon: mouse tracking

Subject: Cocoa in Carbon: mouse tracking
From: David Catmull <email@hidden>

I'm adding some Cocoa dialogs to a Carbon application, and I have it mostly working except for one issue: mouse tracking. My dialogs have text fields, and the mouse cursor doesn't change to the i-beam in those fields... unless you right-click.

I could make an NSTextField subclass that overrides addCursorRect:cursor: (assuming that's what I need) and sets up a Carbon mouse tracking region, but I'm really hoping there's an easier solution. Has anyone dealt with this? Is there some other way I can make sure the Cocoa mouse tracking code does its thing?

I investigated this in the Cocoa In Carbon sample, and found that the mouse cursor only changes the first time the mouse enters the text field.
