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