Re: kEventParamMenuRef (was: _NSGetCarbonMenu)

One last thing: if I have more than one installed events for the same event handler, how can I get the event type ( such as kEventMenuTargetItem, kEventMenuBeginTracking, etc.) so that I know which event to handle? I've been looking in the docs/lists but couldn't find anything...

Thanks!

Luc

One thing though... I'm able to get the item index but I can't seem to be able to get a MenuRef.

MenuRef ref;
error = GetEventParameter( event, kEventParamMenuRef,
typeMenuRef, NULL, sizeof(MenuRef), NULL, &ref );

I get an -9870 error The piece of data you are requesting from an event is not present.

I believe the menu ref is actually the direct object in the event, so you should do something like this:

MenuRef theMenuRef;
OSStatus result = GetEventParameter (theEvent, kEventParamDirectObject,
typeMenuRef, NULL, sizeof (MenuRef), NULL, &theMenuRef);


One of the best places that describes the various carbon events (e.g. parameters along with their types) is the header itself:

Carbon/CarbonEvents.h
