1.11.1 Menu Types
There are three different types of menus: pop-up, pulldown, and pullright menus. The gen-
eral term pop-up menu may describe all three types in certain contexts since menus are
popped up. However, pulldown and pullright menus have distinct characteristics that make
them unique.
Pop-up Menus Pop-up menus are displayed when the user selects the MENU mouse
button over XView objects such as scrollbars or text subwindows. An
OPENLOOK window manager also utilizes pop-up menus in the root
window and from base frame title bars. XView objects handle the dis-
play of menus automatically.
Pulldown Menus Pulldown menus are attached to menu buttons. Menu buttons have a set
of choices associated with them that the user can access only via the
pulldown menu. When the user presses the MENU mouse button over a
menu button, the choices are displayed in the form of a pulldown menu.
If the menu button is selected using the SELECT button, the default
menu item is selected.
Pullright Menus OPEN LOOK provides for items in the menu to have pullright menus
associated with them. Also called cascading menus, these menus are
activated from the user dragging the MENU mouse button to the right of
a menu item that has an arrow pointing to the right. The cascading
menu that results is a pop-up menu that can also have menu items with
pullrights attached.
