Subject Re: Further question about menu context
Date Tue, 14 Sep 2010 15:39:32 GMT
You are correct - there is no way to determine if a menu belongs to a menu bar, menu button,
or context menu - menus don't maintain a reference to any kind of "owner" component, aside
from the parent Menu.Item (which is null if a menu is the root menu).

Using separate actions (which possibly share a common base class) seems like a good idea.

for context menus vs. regular menus.  I (rather naively) thought that I could test to see
if the Menu.Item was ultimately parented by a MenuBar or not to differentiate the regular
window menu from a right-click menu.  Not so – both end up parented by a MenuPopup attached
to the Display.  Then I thought I could use “isContextMenu()” from MenuPopup, which does
work, but not for submenus…. L  Is this a bug, or a misunderstanding on my part?  Is there
any other way to tell whether the menu item is coming from a right-click menu or the menu
bar?  Thanks.

as regular menu items, but with different context.  Right now, I mapped them both to the same
action.  But, maybe I need to make separate actions and that will solve it.  The case where
the action is invoked from a toolbar vs. a menu is solved with the Component being passed
in (also the shortcut key case).
