Creating Menus — The Menu Editor

3-67

You can also

• Select the

Separator above this item check box to display a separator above

the menu item when the menu is first opened.

• Select the

Check mark this item check box to display a check next to the

menu item when the menu is first opened.

A check is particularly useful to indicate the current state of the menu item.

For example, suppose you have a menu item called

Show axes that toggles

the visibility of an axes between visible and invisible each time the user

selects the menu item. If you want a check to appear next to the menu item

when the axes are visible, add the following code to the callback for the

Show

axes

menu item:

if strcmp(get(gcbo, 'Checked'),'on')

set(gcbo, 'Checked', 'off');

else

set(gcbo, 'Checked', 'on');
