619 | POSITION is a position specification. This is either a mouse button | |
620 | event or a list ((XOFFSET YOFFSET) WINDOW) where XOFFSET and YOFFSET | |
621 | are positions in pixels from the top left corner of WINDOW's frame | |
622 | \(WINDOW may be a frame object instead of a window). This controls the | |
623 | position of the center of the first line in the first pane of the | |
624 | menu, not the top left of the menu as a whole. If POSITION is t, it | |
625 | means to use the current mouse position. | |
626 | ||
627 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
628 | The menu items come from key bindings that have a menu string as well as | |
629 | a definition; actually, the \"definition\" in such a key binding looks like | |
630 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
631 | the keymap as a top-level element. | |
632 | ||
633 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
634 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
635 | ||
636 | You can also use a list of keymaps as MENU. Then each keymap makes a | |
637 | separate pane. When MENU is a keymap or a list of keymaps, the return | |
638 | value is a list of events. | |
639 | ||
640 | Alternatively, you can specify a menu of multiple panes with a list of | |
641 | the form (TITLE PANE1 PANE2...), where each pane is a list of | |
642 | form (TITLE ITEM1 ITEM2...). | |
643 | Each ITEM is normally a cons cell (STRING . VALUE); but a string can | |
644 | appear as an item--that makes a nonselectable line in the menu. | |
645 | With this form of menu, the return value is VALUE from the chosen item. | |
646 | ||
647 | If POSITION is nil, don't display the menu at all, just precalculate the | |
648 | cached information about equivalent key sequences. */) | |
