602 | POSITION is a position specification. This is either a mouse button event |
603 | or a list ((XOFFSET YOFFSET) WINDOW) | |
604 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
605 | corner of WINDOW. (WINDOW may be a window or a frame object.) | |
606 | This controls the position of the top left of the menu as a whole. | |
607 | If POSITION is t, it means to use the current mouse position. | |
e0f712ba AC |
608 | |
609 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
610 | The menu items come from key bindings that have a menu string as well as | |
50971a12 | 611 | a definition; actually, the "definition" in such a key binding looks like |
e0f712ba AC |
612 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into |
613 | the keymap as a top-level element. | |
614 | ||
615 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
616 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
617 | ||
50971a12 YM |
618 | You can also use a list of keymaps as MENU. |
619 | Then each keymap makes a separate pane. | |
e0f712ba | 620 | |
50971a12 YM |
621 | When MENU is a keymap or a list of keymaps, the return value is the |
622 | list of events corresponding to the user's choice. Note that | |
623 | `x-popup-menu' does not actually execute the command bound to that | |
624 | sequence of events. | |
625 | ||
626 | Alternatively, you can specify a menu of multiple panes | |
627 | with a list of the form (TITLE PANE1 PANE2...), | |
628 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
629 | Each ITEM is normally a cons cell (STRING . VALUE); | |
630 | but a string can appear as an item--that makes a nonselectable line | |
631 | in the menu. | |
e0f712ba AC |
632 | With this form of menu, the return value is VALUE from the chosen item. |
633 | ||
634 | If POSITION is nil, don't display the menu at all, just precalculate the | |
50971a12 YM |
635 | cached information about equivalent key sequences. |
636 | ||
637 | If the user gets rid of the menu without making a valid choice, for | |
638 | instance by clicking the mouse away from a valid choice or by typing | |
639 | keyboard input, then this normally results in a quit and | |
640 | `x-popup-menu' does not return. But if POSITION is a mouse button | |
641 | event (indicating that the user invoked the menu with the mouse) then | |
642 | no quit occurs and `x-popup-menu' returns nil. */) | |
