Re: [Rubycocoa-talk] anyone work with toolbars?

[Kevin B. <krb...@ma...>]

There's two problems with your code, both in the  
toolbar_itemForItemIdentifier_willBeInsertedIntoToolbar method. The  
first is that when the method is called, itemid is an NSCFString, not  
a Ruby String, and it doesn't get implicitly converted. Just  
inserting 'itemid = itemid.to_s' will fix that though. (If you step  
through that method, you might notice that neither branch of the if  
is being called, because the comparison fails.)

The other problem is that you're passing a string to  
NSToolbarItem#setImage, which expects an NSImage. You can fix this  
easily:

     tbi.setImage "NSApplicationIcon"

becomes:

     tbi.setImage( NSImage.imageNamed( "NSApplicationIcon" ) )

and assuming there's an NSApplicationIcon.{tif,icns,...} in your app  
bundle, it'll work.

Hope this helps. Let me know if anything is unclear.
