I have a NSView that only appears in a window when a certain
activity is in progress, and there's an NSPopUpButton in the view
that acts as a gear menu with actions that relate to the activity
in progress. The issue is that if the button's menu is still open
when activity finishes and the view is removed from the window,
the button is gone but the menu is still displayed, and I can't
get the menu to dismiss before I remove the view.
The method -[NSPopUpButtonCell dismissPopUp] doesn't seem to work.
I've filed <rdar://problem/6216372> on that.
I've tried a bunch of different things to dismiss the popup menu,
but none of them have worked. I'd greatly appreciate hearing about
any proven techniques for dismissing the popup menu. Thanks!

You're looking for -[NSMenu cancelTracking].
Ah yes, thanks! That's 10.5-only? I didn't see it because the app
still supports Tiger, so I was looking in the 10.4 docs. Is there a
10.4 method for this?
Note that this is somewhat against Mac OS X UI conventions, as
menus normally don't go away unless the user dismisses them.
Yes, the UI itself is a little unconventional, because the popup
button itself, along with the containing view, disappears, so I
didn't want to leave a orphaned menu.
Imagine the user is about to click on a menu item, and the menu
vanishes and the user triggers whatever was behind it. Consider
instead handling the case where the user chooses a menu item after
the operation has finished with a gentle error message.
Good point about accidentally triggering what's behind the menu. I
don't know if I want to bother the user with an error message, since
it's a matter of timing. I could disable all the menu items, though,
right?
