e3fbac65 | 787 | corner of WINDOW. (WINDOW may be a window or a frame object.) |
453a4f1b | 788 | This controls the position of the top left of the menu as a whole. |
228299fa GM |
789 | If POSITION is t, it means to use the current mouse position. |
790 | ||
791 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
792 | The menu items come from key bindings that have a menu string as well as | |
793 | a definition; actually, the "definition" in such a key binding looks like | |
794 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
795 | the keymap as a top-level element. | |
796 | ||
797 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
798 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
799 | ||
800 | You can also use a list of keymaps as MENU. | |
801 | Then each keymap makes a separate pane. | |
e3fbac65 LT |
802 | |
803 | When MENU is a keymap or a list of keymaps, the return value is the | |
804 | list of events corresponding to the user's choice. Note that | |
805 | `x-popup-menu' does not actually execute the command bound to that | |
806 | sequence of events. | |
228299fa GM |
807 | |
808 | Alternatively, you can specify a menu of multiple panes | |
809 | with a list of the form (TITLE PANE1 PANE2...), | |
810 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
811 | Each ITEM is normally a cons cell (STRING . VALUE); | |
812 | but a string can appear as an item--that makes a nonselectable line | |
813 | in the menu. | |
814 | With this form of menu, the return value is VALUE from the chosen item. | |
815 | ||
816 | If POSITION is nil, don't display the menu at all, just precalculate the | |
c05fe5d5 LT |
817 | cached information about equivalent key sequences. |
818 | ||
819 | If the user gets rid of the menu without making a valid choice, for | |
820 | instance by clicking the mouse away from a valid choice or by typing | |
821 | keyboard input, then this normally results in a quit and | |
822 | `x-popup-menu' does not return. But if POSITION is a mouse button | |
823 | event (indicating that the user invoked the menu with the mouse) then | |
824 | no quit occurs and `x-popup-menu' returns nil. */) | |
