I've included buttons for Save, Close, Cancel and Refresh on my applications main(only) toolbar, and connected them to the menu bars of the same name. The menu options appear disabled/enabled at the proper times, but the toolbar buttons appear to be constantly enabled. How do I get them to appear visually disabled when their menu options are?

The Dev Guide says that disabling a properly-connected toolbar button will disable the menu option, how do I do the reverse?
