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!
-Jeff
