Our app allows the user to write programs and to create custom menus and menu
items, including setting key equivalents.
Because the key equivalents are under user control and because we re-use some
for multiple purposes, menu items' key equivalents change a lot.
We need to get a chance to update/modify the menus and key equivalents *before*
Cocoa starts looking for menu items that match the key equivalent.
At that time we need the ability to add/remove menus and menu items, set key
equivalents, and enable/disable menu items.
menuNeedsUpdate: is an NSMenuDelegate Procotol that allows us to do exactly
that when the user clicks in the menubar.
https://developer.apple.com/library/mac/documentation/Cocoa/Reference/NSMenuDelegate_Protocol/Reference/Reference.html
We'd love to have menuNeedsUpdate: be called before Cocoa starts calling
menuHasKeyEquivalent:forEvent:target:action:.
menuDidOpen: is too late, according to the docs:
"Special Considerations: Don’t modify the structure of the menu or the
menu items during this method."
Is there any way with OS X 10.6 and later to get this kind of advanced
opportunity to modify menus and items for key presses?
Maybe some other class's delegate?
(Some our customers have 20 years worth of documents/programs which make rely
on this feature, which Carbon's MenuSelect provides to this day.
That is, MenuSelect allowed us to rebuild the menus for both key events and
menu bar events.)
