使用可可在OSX的GL全屏模式下更改光标？

Question

Can anyone provide a sample / link to a sample Cocoa app that changes the 'hardware' cursor in a fullscreen OpenGL Cocoa app? I have been able to create a full screen GL app and an app that changes the cursor by overriding NSView::resetCursorRects but I have not been able to get both to work simultaneously. I've also refitted some of the Apple GL samples (CocoaGL, Custom Cocoa OpenGL, etc) by overriding NSView::resetCursorRects and I haven't been able to get the cursor to change in fullscreen in them either. I have the book "OpenGL Programming on Mac OS X" which also avoids the problem.

@Christopher: I hadn't tried [NSCursor set]. Good call but I made a run at it and no luck. It still returns to the system cursor. I'd say that perhaps something is overriding it in my calls that switch to fullscreen but I've actually tried reseting the mouse cursor in my NSView's draw routine (which gets called repeatedly) and the cursor never switches from the system default.

尝试直接使用NSCursor时，NSView光标rect方法取决于诸如适当大小和可见的NSWindow之类的内容才能正常工作，而在全屏模式下则不一定如此。
