NAME
       XtPopdown, XtCallbackPopdown, MenuPopdown - unmap a pop-up

SYNTAX
       void XtPopdown(popupshell)
             Widget popupshell;

       void XtCallbackPopdown(w, clientdata, calldata)
             Widget w;
             XtPointer clientdata;
             XtPointer calldata;

       void MenuPopdown(shellname)
             String shellname;

ARGUMENTS
       calldata Specifies the callback data, which is not used by this
                 procedure.

       clientdata
                 Specifies a pointer to the XtPopdownID structure.

       popupshell
                 Specifies the widget shell to pop down.

       shellname
                 Specifies the name of the widget shell to pop down.

       w         Specifies the widget.

DESCRIPTION
       The XtPopdown function performs the following:

       ·    Calls XtCheckSubclass to ensure popup_shell is a subclass of
            Shell.

       ·    Checks that popup_shell is currently popped_up; otherwise, it
            generates an error.

       ·    Unmaps popup_shell's window.

       ·    If popup_shell's grab_kind is either XtGrabNonexclusive or
            XtGrabExclusive, it calls XtRemoveGrab.

       ·    Sets pop-up shell's popped_up field to False.

       ·    Calls the callback procedures on the shell's popdown_callback
            list.

       The XtCallbackPopdown function casts the client data parameter to an
       XtPopdownID pointer:

       typedef struct {
            Widget shell_widget;
            Widget enable_widget;
       } XtPopdownIDRec, *XtPopdownID;
The shell_widget is the pop-up shell to pop down, and the enable_widget is
the widget that was used to pop it up.

       XtCallbackPopdown calls XtPopdown with the specified shell_widget and
       then calls XtSetSensitive to resensitize the enable_widget.

       If a shell name is not given, MenuPopdown calls XtPopdown with the
       widget for which the translation is specified.  If a shell_name is
       specified in the translation table, MenuPopdown tries to find the
       shell by looking up the widget tree starting at the parent of the
       widget in which it is invoked.  If it finds a shell with the
       specified name in the pop-up children of that parent, it pops down
       the shell; otherwise, it moves up the parent chain as needed.  If
       MenuPopdown gets to the application top-level shell widget and cannot
       find a matching shell, it generates an error.
