733 | POSITION is a position specification. This is either a mouse button event |
734 | or a list ((XOFFSET YOFFSET) WINDOW) | |
735 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
736 | corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.) | |
737 | This controls the position of the center of the first line | |
738 | in the first pane of the menu, not the top left of the menu as a whole. | |
739 | If POSITION is t, it means to use the current mouse position. | |
740 | ||
741 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
742 | The menu items come from key bindings that have a menu string as well as | |
743 | a definition; actually, the "definition" in such a key binding looks like | |
744 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
745 | the keymap as a top-level element. | |
746 | ||
747 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
748 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
749 | ||
750 | You can also use a list of keymaps as MENU. | |
751 | Then each keymap makes a separate pane. | |
752 | When MENU is a keymap or a list of keymaps, the return value | |
753 | is a list of events. | |
754 | ||
755 | Alternatively, you can specify a menu of multiple panes | |
756 | with a list of the form (TITLE PANE1 PANE2...), | |
757 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
758 | Each ITEM is normally a cons cell (STRING . VALUE); | |
759 | but a string can appear as an item--that makes a nonselectable line | |
760 | in the menu. | |
761 | With this form of menu, the return value is VALUE from the chosen item. | |

1197 | To activate the menu bar, we use the X button-press event | |
ac78b144 | 1198 | that was saved in saved_menu_event. |
88766961 RS |
1199 | That makes the toolkit do its thing. |

1201 | But first we recompute the menu bar contents (the whole tree). | |
1202 | ||
1203 | The reason for saving the button event until here, instead of | |
1204 | passing it to the toolkit right away, is that we can safely | |
1205 | execute Lisp code. */ | |
