Question: how can I create a toolbar item with a custom view…that also allows duplicates? Is this even possible? If I just subclass NSToolbarItem, set the view, and return from allowsDuplicatesInToolbar, then the item works fine, the view works fine (an NSButton in this case), and I can’t drag another copy into the toolbar. Is this just something that can’t be done? –JediKnil

Validation of the items
Controlling Duplicates In The Toolbar
- (BOOL)allowsDuplicatesInToolbar; Return YES to allow dragging duplicate items into the toolbar. By default, if an item with the same identifier is already in the toolbar, dragging in will act as a move of this item. However, for instance, the separator item drags in as a duplicate always. ---- ---- **interface NSObject (NSToolbarItemValidation)**
NSToolbarItemValidation extends the standard validation idea by introducing this new method which is sent to validators for each visible standard NSToolbarItem with a valid target/action pair. Note: This message is sent from NSToolbarItem’s validate method, howevever validate will not send this message for items that have custom views. Moreover, it is sent to the item’s target, NOT to the toolbar delegate. —- —- Standard Toolbar Item Identifiers:

How do I disable the items in NSToolbar during runtime?
Implement this method:
It should be noted that, at least in my experience, the above method needs to be implemented in the NSToolbarItem TARGET, not in the Toolbar Controller itself.
Yes, of course, this is exactly like Cocoa’s other methods.
Is it possible to prevent the user from moving particular items in a toolbar? E.g. in X-code with the All-in-One layout set the page switching item can�t be (re)moved. I found the private method -NSToolbarItem _setIsUserRemovable: but passing NO still allows the user to move the item around in the toolbar, just not remove it.
Apparently when you open a sheet on your window, it will disable all the buttons on your toolbar. Then after the sheet ends, it will restore the state of the buttons afterwards. The trouble is, if you change the enabled state of the buttons in your alertDidEnd:returnCode:contextInfo: method, your change will be lost. Even worse, if you are attempting to bind the enabled state of the button through a binding, this restore process apparently ignores your binding and stomps all over it. The only solution I know of is to do an ugly hack using performSelector: to reset your desired state of the button on the next iteration through the runloop. Unfortunately there is enough brain-damage in Cocoa toolbars that the enabled bindings are close to useless.
