742 or a list ((XOFFSET YOFFSET) WINDOW)
743 where XOFFSET and YOFFSET are positions in pixels from the top left
744 corner of WINDOW. (WINDOW may be a window or a frame object.)
745 This controls the position of the top left of the menu as a whole.
746 If POSITION is t, it means to use the current mouse position.
748 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
749 The menu items come from key bindings that have a menu string as well as
750 a definition; actually, the "definition" in such a key binding looks like
751 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into
752 the keymap as a top-level element.
754 If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
755 Otherwise, REAL-DEFINITION should be a valid key binding definition.
757 You can also use a list of keymaps as MENU.
758 Then each keymap makes a separate pane.
760 When MENU is a keymap or a list of keymaps, the return value is the
761 list of events corresponding to the user's choice. Note that
762 `x-popup-menu' does not actually execute the command bound to that
765 Alternatively, you can specify a menu of multiple panes
766 with a list of the form (TITLE PANE1 PANE2...),
767 where each pane is a list of form (TITLE ITEM1 ITEM2...).
768 Each ITEM is normally a cons cell (STRING . VALUE);
769 but a string can appear as an item--that makes a nonselectable line
771 With this form of menu, the return value is VALUE from the chosen item.
773 If POSITION is nil, don't display the menu at all, just precalculate the
774 cached information about equivalent key sequences.
776 If the user gets rid of the menu without making a valid choice, for
777 instance by clicking the mouse away from a valid choice or by typing
778 keyboard input, then this normally results in a quit and
779 `x-popup-menu' does not return. But if POSITION is a mouse button
780 event (indicating that the user invoked the menu with the mouse) then
781 no quit occurs and `x-popup-menu' returns nil. */)
