78589e07 RS |

675 | This controls the position of the center of the first line\n\ | |

677 | If POSITION is t, it means to use the current mouse position.\n\ | |
678 | \n\ | |
679 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\ | |
680 | The menu items come from key bindings that have a menu string as well as\n\ | |
681 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
682 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
683 | the keymap as a top-level element.\n\n\ | |
684 | You can also use a list of keymaps as MENU.\n\ | |
685 | Then each keymap makes a separate pane.\n\ | |
686 | When MENU is a keymap or a list of keymaps, the return value\n\ | |
687 | is a list of events.\n\n\ | |
688 | Alternatively, you can specify a menu of multiple panes\n\ | |
689 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
690 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
691 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
692 | but a string can appear as an item--that makes a nonselectable line\n\ | |
693 | in the menu.\n\ | |
694 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
695 | \n\ | |
