722 | POSITION is a position specification. This is either a mouse button event |
723 | or a list ((XOFFSET YOFFSET) WINDOW) | |
724 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
725 | corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.) | |
726 | This controls the position of the center of the first line | |
727 | in the first pane of the menu, not the top left of the menu as a whole. | |
728 | If POSITION is t, it means to use the current mouse position. | |
729 | ||
730 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
731 | The menu items come from key bindings that have a menu string as well as | |
732 | a definition; actually, the "definition" in such a key binding looks like | |
733 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
734 | the keymap as a top-level element. | |
735 | ||
736 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
737 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
738 | ||
739 | You can also use a list of keymaps as MENU. | |
740 | Then each keymap makes a separate pane. | |
741 | When MENU is a keymap or a list of keymaps, the return value | |
742 | is a list of events. | |
743 | ||
744 | Alternatively, you can specify a menu of multiple panes | |
745 | with a list of the form (TITLE PANE1 PANE2...), | |
746 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
747 | Each ITEM is normally a cons cell (STRING . VALUE); | |
748 | but a string can appear as an item--that makes a nonselectable line | |
749 | in the menu. | |
750 | With this form of menu, the return value is VALUE from the chosen item. | |
