Hi,

I managed to get it to work by changing NSPostASAP to NSPostNow (hoping that this is ok).

One last thing, how can I get information about the control from NSResponder?

Thanks!

Luc

Basically there's a text field, check boxes, radio buttons and buttons. Like I said, makeFirstResponder is called every time I tab through the controls but the notification is only received once, when the window has closed.

How did you subscribe to the notification? Did you try using the delegate pathway?


>From the code I see I don't see why you would be getting the behavior you described.

Are you running any type of run loop of your own while this window is up?
Is it a modal window of some type?

here's how I register:

NSNotificationCenter* center = [NSNotificationCenter defaultCenter];

	[center addObserver:self
						 selector:@selector(windowDidMakeFirstResponder:)
								 name:@"WindowDidMakeFirstResponder" object:nil];

Is the window you are working with a modal window... application modal, document modal (sheet), etc.?


My guess would be that you either have a sub-runloop in place or the main runloop is in a particular mode while the window is being displayed that is preventing delivery of the notification.

As a test you could modify the NSWindow subclass to change the modes that the event should be delivered under.

Replace...

[[NSNotificationQueue defaultQueue] enqueueNotification:notif postingStyle:NSPostASAP];

...with something like the following (consider adding NSEventTrackingRunLoopMode as well if needed)...

NSNotificationQueue dq = [NSNotificationQueue defaultQueue]
[dq enqueueNotification:notif
postingStyle:NSPostASAP
coalesceMask:NSNotificationCoalescingOnName | NSNotificationCoalescingOnSender
forModes:[NSArray arrayWithObjects:NSDefaultRunLoopMode, NSModalPanelRunLoopMode, nil]];
