89 | POSITION is a position specification. This is either a mouse button event\n\ |
90 | or a list ((XOFFSET YOFFSET) WINDOW)\n\ | |
dcfdbac7 | 91 | where XOFFSET and YOFFSET are positions in characters from the top left\n\ |

dcfdbac7 JB |

94 | in the first pane of the menu, not the top left of the menu as a whole.\n\ | |
95 | \n\ | |
088831f6 RS |
96 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\ |
97 | The menu items come from key bindings that have a menu string as well as\n\ | |
98 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
99 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
100 | the keymap as a top-level element.\n\n\ | |
101 | You can also use a list of keymaps as MENU.\n\ | |
102 | Then each keymap makes a separate pane.\n\n\ | |
103 | Alternatively, you can specify a menu of multiple panes\n\ | |
104 | with a list of the form\n\ | |
105 | \(TITLE PANE1 PANE2...), where each pane is a list of form\n\ | |
dcfdbac7 | 106 | \(TITLE (LINE ITEM)...). Each line should be a string, and item should\n\ |
dbc4e1c1 | 107 | be the return value for that line (i.e. if it is selected).") |
