Hello,
I have a rather complicated undo setting
My document Object has a Array of independent graphical items
(containing some properties).
Each item should have its own undo/redo based of selection in the
interface. So I select Item_1, modify it, select Item_2 and modify it,
too. Then I want to be able to select item_1 again and undo its changes.
I know that this is very unusual and may confuse users but it needs to
be this way.
I have a Instance of NSUndoManager in each of my items. But how do I
tell the menu which undoManager is "active" (to display an appropriate
actionName).
any suggestion is welcome.
Thanks in advance
Georg
