790 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
791 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
792 | ||
793 | You can also use a list of keymaps as MENU. | |
794 | Then each keymap makes a separate pane. | |
e3fbac65 LT |
795 | |
796 | When MENU is a keymap or a list of keymaps, the return value is the | |
797 | list of events corresponding to the user's choice. Note that | |
798 | `x-popup-menu' does not actually execute the command bound to that | |
799 | sequence of events. | |
228299fa GM |
800 | |
801 | Alternatively, you can specify a menu of multiple panes | |
802 | with a list of the form (TITLE PANE1 PANE2...), | |
803 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
804 | Each ITEM is normally a cons cell (STRING . VALUE); | |
805 | but a string can appear as an item--that makes a nonselectable line | |
806 | in the menu. | |
807 | With this form of menu, the return value is VALUE from the chosen item. | |
808 | ||
809 | If POSITION is nil, don't display the menu at all, just precalculate the | |
c05fe5d5 LT |
810 | cached information about equivalent key sequences. |
811 | ||
812 | If the user gets rid of the menu without making a valid choice, for | |
813 | instance by clicking the mouse away from a valid choice or by typing | |
814 | keyboard input, then this normally results in a quit and | |
815 | `x-popup-menu' does not return. But if POSITION is a mouse button | |
816 | event (indicating that the user invoked the menu with the mouse) then | |
817 | no quit occurs and `x-popup-menu' returns nil. */) | |
