245 | POSITION is a position specification. This is either a mouse button event |
246 | or a list ((XOFFSET YOFFSET) WINDOW) | |
247 | where XOFFSET and YOFFSET are positions in pixels from the top left | |
e3fbac65 | 248 | corner of WINDOW. (WINDOW may be a window or a frame object.) |
453a4f1b | 249 | This controls the position of the top left of the menu as a whole. |
228299fa GM |
250 | If POSITION is t, it means to use the current mouse position. |
251 | ||
252 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
253 | The menu items come from key bindings that have a menu string as well as | |
254 | a definition; actually, the "definition" in such a key binding looks like | |
255 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
256 | the keymap as a top-level element. | |
257 | ||
258 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
259 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
260 | ||
261 | You can also use a list of keymaps as MENU. | |
262 | Then each keymap makes a separate pane. | |
e3fbac65 LT |
263 | |
264 | When MENU is a keymap or a list of keymaps, the return value is the | |
265 | list of events corresponding to the user's choice. Note that | |
266 | `x-popup-menu' does not actually execute the command bound to that | |
267 | sequence of events. | |
228299fa GM |
268 | |
269 | Alternatively, you can specify a menu of multiple panes | |
270 | with a list of the form (TITLE PANE1 PANE2...), | |
271 | where each pane is a list of form (TITLE ITEM1 ITEM2...). | |
272 | Each ITEM is normally a cons cell (STRING . VALUE); | |
273 | but a string can appear as an item--that makes a nonselectable line | |
274 | in the menu. | |
275 | With this form of menu, the return value is VALUE from the chosen item. | |
276 | ||
277 | If POSITION is nil, don't display the menu at all, just precalculate the | |
c05fe5d5 LT |
278 | cached information about equivalent key sequences. |
279 | ||
280 | If the user gets rid of the menu without making a valid choice, for | |
281 | instance by clicking the mouse away from a valid choice or by typing | |
282 | keyboard input, then this normally results in a quit and | |
283 | `x-popup-menu' does not return. But if POSITION is a mouse button | |
284 | event (indicating that the user invoked the menu with the mouse) then | |
285 | no quit occurs and `x-popup-menu' returns nil. */) | |
