This example shows off the Menu, MenuButton, and MenuBar widgets.

• MenuButton is your basic button that pops up a Menu when clicked.
• MenuBar is a specialized Frame that attaches to the top of the parent (usually the window) and provides a simple API to add menus and items.
• Menu is the underlying "pop-up and select an item" widget.

From your terminal, just type go run main.go or make run from this example's directory.
