| 646 | POSITION is a position specification. This is either a mouse button event |
| 647 | or a list ((XOFFSET YOFFSET) WINDOW) |
| 648 | where XOFFSET and YOFFSET are positions in pixels from the top left |
| 649 | corner of WINDOW. (WINDOW may be a window or a frame object.) |
| 650 | This controls the position of the top left of the menu as a whole. |
| 651 | If POSITION is t, it means to use the current mouse position. |
| 652 | |
| 653 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. |
| 654 | The menu items come from key bindings that have a menu string as well as |
| 655 | a definition; actually, the "definition" in such a key binding looks like |
| 656 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into |
| 657 | the keymap as a top-level element. |
| 658 | |
| 659 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. |
| 660 | Otherwise, REAL-DEFINITION should be a valid key binding definition. |
| 661 | |
| 662 | You can also use a list of keymaps as MENU. |
| 663 | Then each keymap makes a separate pane. |
| 664 | |
| 665 | When MENU is a keymap or a list of keymaps, the return value is the |
| 666 | list of events corresponding to the user's choice. Note that |
| 667 | `x-popup-menu' does not actually execute the command bound to that |
| 668 | sequence of events. |
| 669 | |
| 670 | Alternatively, you can specify a menu of multiple panes |
| 671 | with a list of the form (TITLE PANE1 PANE2...), |
| 672 | where each pane is a list of form (TITLE ITEM1 ITEM2...). |
| 673 | Each ITEM is normally a cons cell (STRING . VALUE); |
| 674 | but a string can appear as an item--that makes a nonselectable line |
| 675 | in the menu. |
| 676 | With this form of menu, the return value is VALUE from the chosen item. |
| 677 | |
| 678 | If POSITION is nil, don't display the menu at all, just precalculate the |
| 679 | cached information about equivalent key sequences. |
| 680 | |
| 681 | If the user gets rid of the menu without making a valid choice, for |
| 682 | instance by clicking the mouse away from a valid choice or by typing |
| 683 | keyboard input, then this normally results in a quit and |
| 684 | `x-popup-menu' does not return. But if POSITION is a mouse button |
| 685 | event (indicating that the user invoked the menu with the mouse) then |
| 686 | no quit occurs and `x-popup-menu' returns nil. */) |
