Hello,
A user has just pointed out a very strange situation in my program concerning
keyboard shortcuts that I have been unable to fathom, so I was wondering if
anyone here might have seen something like it before or have an idea as to what
might cause it. The strangeness is that this doesn't seem to be related to code
as far as I can see (which usually means that it is related to code and I just
can't see it).
While a document in my document-based app is open, if the user goes to System
Preferences > Keyboard & Mouse > Keyboard Shortcuts and assigns a custom
keyboard shortcut to one of the menu commands in my app, suddenly the cmd-C
keyboard shortcut for Copy in the Edit menu disappears (and I hasten to add
that it doesn't matter what keyboard shortcut you assign in Keyboard
Preferences - assign ctrl-cmd-0 for "Delete" and cmd-C is suddenly no longer
available for "Copy" - weird). If the user quits the app and restarts it, all
keyboard shortcuts are restored. If no document is open while assigning
keyboard shortcuts, there are no problems. But if the program is running and a
document is open, assigning a keyboard shortcut via System Preferences causes
certain other keyboard shortcuts - Copy for sure, possibly others I have yet to
notice - to stop working. This seems very strange to me. I tried unhooking the
delegate of my Edit menu. I tried commenting out all
NSMenu delegate methods, in case they were interfering somehow... I tried
getting rid of menu items that might be similar to Copy (Copy Ruler, Copy Font
etc), just in case... But so far I just cannot fathom a reason why arbitrary
keyboard shortcuts assigned via System Preferences would interfere with
established and totally different keyboard shortcuts in my running app.
Has anyone seen anything like this? If anyone can point me in the direction of
where the problem might lie - I know there's not much to go on but I can't see
where in code this could be caused as copy: just uses the generic copy: first
responder command and my app doesn't interfere with it - I would be very
grateful.
Many thanks in advance and all the best,
Keith
