If you look in NSEvent.h you will see :
#if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_5
/* -eventRef and +eventWithEventRef: are valid for all events */
/* -eventRef returns an EventRef corresponding to the NSEvent. The EventRef is
retained by the NSEvent, so will be valid as long as the NSEvent is valid, and
will be released when the NSEvent is freed. You can use RetainEvent to extend
the lifetime of the EventRef, with a corresponding ReleaseEvent when you are
done with it. If there is no EventRef corresponding to the NSEvent, -eventRef
will return NULL.
*/
- (const void * /* EventRef */)eventRef;
...
I.e. eventRef is only supported by Apple on 10.5 and newer.

Subject: Getting Carbon EventRef from cocoa NSEvent
Hi All,
For some requirement in my product, I have embedded my Carbon window inside
Cocoa window using addChildWindow method.
For getting my carbon window UI (keyboard and mouse) events working, I had to
watch cocoa events for NSWindow of Carbon window and then redispatch carbon
eventRef’s to Carbon window using SendEventToEventTarget API.
So while converting Cocoa event to carbon events, I used the following piece of
code
- (void)keyDown:(NSEvent *)theEvent
{
OSStatus status; //1
EventRef carbonEvnt; //2
carbonEvnt = (EventRef) [theEvent eventRef]; //3
}
But the above NSEvent method eventRef is crashing (at 3) on Tiger. But on
Leopard it works fine.
Am I doing anything wrong here?
Thanks
