7.2.3.3 Menu boxes

In addition to groups of buttons, groups of menu items can be created. All of these are subclasses of the class <menu-box>.

A <push-menu-box> is a group of several standard menu items. A <push-menu-box> is the menu-specific version of <push-box>. This is the default type of <menu-box>.

A <radio-menu-box> is a group of several radio menu items. A <radio-menu-box> is the menu-specific version of <radio-box>.

A <check-menu-box> is a group of several check menu items. A <check-menu-box> is the menu-specific version of <check-box>.

Figure 7.9 Types of menu boxes

All the items in a menu box are grouped together on the menu in which they are placed. A divider separates these items visually from any other menu buttons or menu boxes placed above or below in the menu. It is useful to use push menu boxes to group together related menu commands such as Cut, Copy, and Paste, where the operations performed by the commands are related, even though the commands themselves do not act as a group. Note that you can also use command tables to create and group related menu commands. See Chapter 6, "Using Command Tables" for more details.
