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