hi all,
i like to create some menus, set them as the main menu bar, then maybe
delete them, and create some more menus, use them, etc.
but i can't find any way to do this with cocoa
here is the problem
when you add a submenu (setSubMenu:forItem) the retain count on the submenu
goes up by one
but when you delete that item, or set its submenu to nil, the retain count
does not change
if you ever delete a menu that has a submenu you will get a crash, but there
is no way to unassociate the menu and the submenu
another problem: when you set the main menu bar [NSApp setMainMenu:themenu]
the retain count on themenu goes up by a lot, i can't predict it, but maybe
4 or 5
if you set the main menu bar to nil the retain count does not change on the
original main menu
so given all this, i can't find a way to create and delete menus without
crashes or memory leaks
am i doing something wrong?
thanks
bill appleton
