1021 | doc: /* Pop up a deck-of-cards menu and return user's selection. | |
1022 | POSITION is a position specification. This is either a mouse button event | |
1023 | or a list ((XOFFSET YOFFSET) WINDOW) | |
1024 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
1025 | corner of WINDOW. (WINDOW may be a window or a frame object.) | |
1026 | This controls the position of the top left of the menu as a whole. | |
1027 | If POSITION is t, it means to use the current mouse position. | |
1028 | ||
1029 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
1030 | The menu items come from key bindings that have a menu string as well as | |
1031 | a definition; actually, the "definition" in such a key binding looks like | |
1032 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
1033 | the keymap as a top-level element. | |
1034 | ||
1035 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
1036 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
1037 | ||
1038 | You can also use a list of keymaps as MENU. | |
1039 | Then each keymap makes a separate pane. | |
1040 | ||
1041 | When MENU is a keymap or a list of keymaps, the return value is the | |
1042 | list of events corresponding to the user's choice. Note that | |
1043 | `x-popup-menu' does not actually execute the command bound to that | |
1044 | sequence of events. | |
1045 | ||
1046 | Alternatively, you can specify a menu of multiple panes | |
1047 | with a list of the form (TITLE PANE1 PANE2...), | |
1048 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
1049 | Each ITEM is normally a cons cell (STRING . VALUE); | |
1050 | but a string can appear as an item--that makes a nonselectable line | |
1051 | in the menu. | |
1052 | With this form of menu, the return value is VALUE from the chosen item. | |
1053 | ||
1054 | If POSITION is nil, don't display the menu at all, just precalculate the | |
1055 | cached information about equivalent key sequences. | |
1056 | ||
1057 | If the user gets rid of the menu without making a valid choice, for | |
1058 | instance by clicking the mouse away from a valid choice or by typing | |
1059 | keyboard input, then this normally results in a quit and | |
1060 | `x-popup-menu' does not return. But if POSITION is a mouse button | |
1061 | event (indicating that the user invoked the menu with the mouse) then | |
1062 | no quit occurs and `x-popup-menu' returns nil. */) | |
