In your NSView:
- (void)viewDidMoveToWindow
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(windowResized:) name:NSWindowDidResizeNotification
object:[self window]];
}
- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
[super dealloc];
}
- (void)windowResized:(NSNotification *)notification;
{
NSSize size = [[self window] frame].size;
NSLog(@"window width = %f, window height = %f", size.width,
size.height);
}
Hope this helps!

I don't think I am presenting my question well enough. Let me try
again.
I have a custom NSView object with a NSOpenGLContext in it. When
the window is resized how do you capture the window height and width
(not the derived NSView object's height/width, it doesn't change) so
I can adjust the view port appropriately.
Assume that I need a custom NSView. It seems this behavior comes
for free when inheriting from NSOpenGLView.
Posters often suggest that I go to the online apple docs and figure
it out. I am looking online after I make all these posts. The
majority of the time I get a response sooner than I figure it out.
I am on the steep slope of the learning curve and will be off in
short order.
Thanks again for all the help.

For a window:
If you are registered as the delegate you can handle the
windowWillResize:toSize: call to get called just before the
reisize. Or, If you want the message after the resize, you can
handle the windowDidResize: call.
For a view:
You can register to receive the NSViewFrameDidChangeNotification
notification. This is called after the frame of the view has been
changed. I don't know of a message to track it real time.

How do you detect a resize event?
I can see that lockFocus and drawRect are getting called.
Is there a method to help determine if the user is resizing the
window?
thanks,
