Having subclassed NSToolbar, I am now trying to get a notification
of changes done by the user using the customization palette.
This works fine for the removal of items (toolbarDidRemoveItem:),
but I can't see a way to get notified of added/moved items after the
fact.
The only notification I can get is toolbarWillAddItem:, but that's
obviously before the addition, which is not very helpful.
I have tried implementing insertItemWithItemIdentifier: and also
setConfigurationFromDictionary:, but it seems that the palette
doesn't go through these.
Short of regularly monitoring the tool bar for possible changes, I
don't know what to do...
There is no built-in way to do what you want that I know of. There may
be third-party subclasses or substitutes, but none that I recall.
You can know when the customization palette is invoked, so all you
need to check for is when it is closed and then check for changes. You
could take a snapshot at -runCustomizationPalette:, then set a timer
that checks -customizationPaletteIsRunning until it returns NO, at
which time you check for changes. You are still polling, but at least
it is relatively lightweight.
