780 POSITION is a position specification. This is either a mouse button event
781 or a list ((XOFFSET YOFFSET) WINDOW)
782 where XOFFSET and YOFFSET are positions in pixels from the top left
783 corner of WINDOW. (WINDOW may be a window or a frame object.)
784 This controls the position of the top left of the menu as a whole.
785 If POSITION is t, it means to use the current mouse position.
787 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
788 The menu items come from key bindings that have a menu string as well as
789 a definition; actually, the "definition" in such a key binding looks like
790 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into
791 the keymap as a top-level element.
793 If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
794 Otherwise, REAL-DEFINITION should be a valid key binding definition.
796 You can also use a list of keymaps as MENU.
797 Then each keymap makes a separate pane.
799 When MENU is a keymap or a list of keymaps, the return value is the
800 list of events corresponding to the user's choice. Note that
801 `x-popup-menu' does not actually execute the command bound to that
804 Alternatively, you can specify a menu of multiple panes
805 with a list of the form (TITLE PANE1 PANE2...),
806 where each pane is a list of form (TITLE ITEM1 ITEM2...).
807 Each ITEM is normally a cons cell (STRING . VALUE);
808 but a string can appear as an item--that makes a nonselectable line
810 With this form of menu, the return value is VALUE from the chosen item.
812 If POSITION is nil, don't display the menu at all, just precalculate the
813 cached information about equivalent key sequences.
815 If the user gets rid of the menu without making a valid choice, for
816 instance by clicking the mouse away from a valid choice or by typing
817 keyboard input, then this normally results in a quit and
818 `x-popup-menu' does not return. But if POSITION is a mouse button
819 event (indicating that the user invoked the menu with the mouse) then
820 no quit occurs and `x-popup-menu' returns nil. */)
