543 | POSITION is a position specification. This is either a mouse button event |
544 | or a list ((XOFFSET YOFFSET) WINDOW) | |
545 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
546 | corner of WINDOW. (WINDOW may be a window or a frame object.) | |
547 | This controls the position of the top left of the menu as a whole. | |
548 | If POSITION is t, it means to use the current mouse position. | |
e0f712ba AC |
549 | |
550 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
551 | The menu items come from key bindings that have a menu string as well as | |
50971a12 | 552 | a definition; actually, the "definition" in such a key binding looks like |
e0f712ba AC |
553 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into |
554 | the keymap as a top-level element. | |
555 | ||
556 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
557 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
558 | ||
50971a12 YM |
559 | You can also use a list of keymaps as MENU. |
560 | Then each keymap makes a separate pane. | |
e0f712ba | 561 | |
50971a12 YM |
562 | When MENU is a keymap or a list of keymaps, the return value is the |
563 | list of events corresponding to the user's choice. Note that | |
564 | `x-popup-menu' does not actually execute the command bound to that | |
565 | sequence of events. | |
566 | ||
567 | Alternatively, you can specify a menu of multiple panes | |
568 | with a list of the form (TITLE PANE1 PANE2...), | |
569 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
570 | Each ITEM is normally a cons cell (STRING . VALUE); | |
571 | but a string can appear as an item--that makes a nonselectable line | |
572 | in the menu. | |
e0f712ba AC |
573 | With this form of menu, the return value is VALUE from the chosen item. |
574 | ||
575 | If POSITION is nil, don't display the menu at all, just precalculate the | |
50971a12 YM |
576 | cached information about equivalent key sequences. |
577 | ||
578 | If the user gets rid of the menu without making a valid choice, for | |
579 | instance by clicking the mouse away from a valid choice or by typing | |
580 | keyboard input, then this normally results in a quit and | |
581 | `x-popup-menu' does not return. But if POSITION is a mouse button | |
582 | event (indicating that the user invoked the menu with the mouse) then | |
583 | no quit occurs and `x-popup-menu' returns nil. */) | |
