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