Create Menus in a GUIDE GUI

• “CreateaMenu”onpage6-106

• “Add Items to a Menu” on page 6-109

• “Additional Drop-Down M enus” on page 6-111

• “Cascading Menus” on page 6-112

When you create a drop-down menu, GUID E adds its title to the G U I m enu

bar. You then can create menu items for that menu. Each menu item can

have a cascading menu, also known as a submenu, and these items can have

cascading menus, and so on.

Note On Mac platforms, MATLAB creates menus on the menu bar at the

top of the screen, to the right o f the right-most existing menu, not at the

top of figure windows.
