1097 | POSITION is a position specification. This is either a mouse button event\n\ | |
1098 | or a list ((XOFFSET YOFFSET) WINDOW)\n\ | |
1099 | where XOFFSET and YOFFSET are positions in pixels from the top left\n\ | |
1100 | corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.)\n\ | |
1101 | This controls the position of the center of the first line\n\ | |
1102 | in the first pane of the menu, not the top left of the menu as a whole.\n\ | |
1103 | If POSITION is t, it means to use the current mouse position.\n\ | |
1104 | \n\ | |
1105 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\ | |
1106 | The menu items come from key bindings that have a menu string as well as\n\ | |
1107 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
1108 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
1109 | the keymap as a top-level element.\n\n\ | |
1110 | You can also use a list of keymaps as MENU.\n\ | |
1111 | Then each keymap makes a separate pane.\n\ | |
1112 | When MENU is a keymap or a list of keymaps, the return value\n\ | |
1113 | is a list of events.\n\n\ | |
1114 | Alternatively, you can specify a menu of multiple panes\n\ | |
1115 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
1116 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
1117 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
1118 | but a string can appear as an item--that makes a nonselectable line\n\ | |
1119 | in the menu.\n\ | |
1120 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
1121 | \n\ | |
