Element: MenuItem.
Text: A button for menus.
Description: A MenuItem is the particular implementation of Button for menus. Thus, it is used to invoke actions on menus. It can display a text, an image, or both. The action is invoked when the button is clicked (i.e. pressed and released).
Note: Play, Pause and Reset are
menu items. The top two options are Menu
elements.
Buttons can be disabled using the "Enabled" property. In this case, the interface is greyed out.
