In my Finder CM plug-in, I'm using kEventMenuPopulate menu kind
event to dynamically modify the CM's contents, add icons to menu
items etc. That's a known technique, even presented in Apple's
SampleCM source code. However, that functionality seems to be broken
in Leopard.
In Tiger (and Panther) that worked with all the menus I added myself
either using AEDesc, AERecord and AEDescList instances, or adding
them dynamically as shown in the sample code. But it also worked for
the root menu of the CM (I need to dynamically change name and add
submenu to one menu item in the CM's root). In Leopard,
kEventMenuPopulate still works for all other menus, but not for the
root menu of the CM, or better said, it's not root menu anymore, now
its submenu of the root menu item titled "More". kEventMenuPopulate
seems not to be sent when that submenu is to be populated! That
completely breaks a particular feature of my plug-in.
I assume you some of you know what has changed in a way CM plug-ins
are treated in Leopard. I was trying to find any information about
that in release and technical notes about Leopard, but I was unable
to find anything. Perhaps I didn't look good enough. Can you please
point out to some document or anything else which will guide me in
how to catch kEventMenuPopulate for CM root menu item "More"? I
remember that I read somewhere (mailing list?) that there would be
changes in the way Leopard works with third party CM plug-ins, but I
couldn't find any more info on that matter.
I think what probably happened is that Finder changed the way that it
displays contextual menus in Leopard. As you noticed, Finder now
displays the contextual menu items as a submenu of its main menu.
I do believe that kEventMenuPopulate should be sent to the submenu
before it is opened. Have you tried using
DebugTraceEventByName("kEventMenuPopulate", 1) from within gdb to see
if the event is being sent?
