Re: NSToolbarItem with custom view in Interface Builder 3 (Leopard)
Hey Gunnar - You won't be able to make this work with an instance of custom view dragged from the library. Here are a couple of suggestions for workarounds: You could add an outlet to the toolbar item you'd like to use a custom view with, and then place the custom view at the top level of your NIB, and also add an outlet to it. In awakeFromNib, you could call setView: on the toolbar item with the correct view. Alternatively, you could use a view object that wasn't a custom view. Interface Builder doesn't provide a view object in the library that isn't a specific subclass or NSView, or a custom view, but you can get a hold of a plain NSView by copying and pasting one from someplace else. For example, copying a window's content view by using Interface Builder's outline view will get you a vanilla instance of NSView. Paste one into the top level of a document and resize it to a reasonable size, and and then you can drag it from the document window into the toolbar.

Re: NSToolbarItem with custom view in Interface Builder 3 (Leopard)
Howdy Jon, Thanks for the tips, I'll give that a try. The first suggestion sounds close to where I was going to go, except I hadn't thought of instantiating the view in the NIB file. Great idea. Your alternative suggestion sounds interesting but I'm not sure I understand it. Would I then set the class name in the Identity pane of this pasted, plain NSView to my custom class? What's different about this plain NSView from the custom view dragged from the library? Is this a bug in Interface Builder, or did I misread the linked documentation? From the doc: The procedure for adding a custom view item is very similar to that for a custom image item. (“Custom” in this context means any object from the Interface Builder library as well as instances of a custom NSView subclass.) Just drag any view object from the library onto the Allowed Toolbar Items area. Click the item once and press Command-1 to display the Attributes pane for the object as a toolbar item; click again to edit the attributes of the item as itself. You should modify the size of the custom view item in the Size pane of the inspector, not directly. If you drag a Custom View object into the allowed-items set, click it twice and set the name of the custom NSView class in the Identity pane of the inspector (Command-6).

What's different about this plain NSView from the custom view dragged from the library? The Custom View has additional behavior beyond an NSView. One way they are different is that when a custom view is instantiated from a NIB file it receives the initWithFrame: message instead of initWithCoder:. Is this a bug in Interface Builder, or did I misread the linked documentation? This is a bug in Interface Builder.
