This package creates a Mac-native toolbar (based on the Cocoa NSToolbar) for use in Tk windows. The The toolbar items are selectable, as in standard Cocoa preferences windows. The package offers a basic implementation of the NSToolbar library; it displays toolbar buttons, with labels and images, and does not display other Mac-native widgets such as the Cocoa searchfield. It does not allow customization, nor can it display Tk widgets.
