658 | POSITION is a position specification. This is either a mouse button event |
659 | or a list ((XOFFSET YOFFSET) WINDOW) | |
660 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
661 | corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.) | |
662 | This controls the position of the center of the first line | |
663 | in the first pane of the menu, not the top left of the menu as a whole. | |
664 | If POSITION is t, it means to use the current mouse position. | |
665 | ||
666 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
667 | The menu items come from key bindings that have a menu string as well as | |
668 | a definition; actually, the "definition" in such a key binding looks like | |
669 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
670 | the keymap as a top-level element. | |
671 | ||
672 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
673 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
674 | ||
675 | You can also use a list of keymaps as MENU. | |
676 | Then each keymap makes a separate pane. | |
677 | When MENU is a keymap or a list of keymaps, the return value | |
678 | is a list of events. | |
679 | ||
680 | Alternatively, you can specify a menu of multiple panes | |
681 | with a list of the form (TITLE PANE1 PANE2...), | |
682 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
683 | Each ITEM is normally a cons cell (STRING . VALUE); | |
684 | but a string can appear as an item--that makes a nonselectable line | |
685 | in the menu. | |
686 | With this form of menu, the return value is VALUE from the chosen item. | |
687 | ||
688 | If POSITION is nil, don't display the menu at all, just precalculate the | |
