I would like to have the facility of undoing deleting of a window.
The best way that I thought I could do this is was to use the
UndoManager belonging of my NSApplication. However when I try to get
the undoManager for the application by calling:
[ NSApp undoManager ]
I get a nil pointer.
Also I could not see any straight forward way of setting an
undoManager for a NSResponder.
Any suggestions how I can resolve this issue.
AFAIK, of the NSResponders only NSWindow creates its own
NSUndoManager. Now, any responder on a window will automatically
search up the responder chain for an undo manager, so it should
automatically get the window's.
