I've created an interface nib/xib file. The app is basically working, which is cool. The standard toolbar buttons look bad, they're glossy and raised, while most apps in Lion have the flat, inner bevel look. So I created some image toolbar buttons and put them in the toolbar and they look great, but they're all disabled by default.
Is there a way to give these the correct state in InterfaceBuilder or do I have to use code to give them the proper state.
Cocoa and Objective C are very unfamiliar so it would be helpful to me if I just knew what to search for. Most of my searching brings me results for creating custom buttons for iOS.
