DESCRIPTION

35       The XtPopdown function performs the following:
36
37       ·    Calls XtCheckSubclass to ensure popup_shell is a subclass of
38            Shell.
39
40       ·    Checks that popup_shell is currently popped_up; otherwise, it gen‐
41            erates an error.
42
43       ·    Unmaps popup_shell's window.
44
45       ·    If popup_shell's grab_kind is either XtGrabNonexclusive or
46            XtGrabExclusive, it calls XtRemoveGrab.
47
48       ·    Sets pop-up shell's popped_up field to False.
49
50       ·    Calls the callback procedures on the shell's popdown_callback
51            list.
52
53       The XtCallbackPopdown function casts the client data parameter to an
54       XtPopdownID pointer:
55
56              typedef struct {
57                      Widget shell_widget;
58                      Widget enable_widget;
59              } XtPopdownIDRec, *XtPopdownID;
60
61       The shell_widget is the pop-up shell to pop down, and the enable_widget
62       is the widget that was used to pop it up.
63
64       XtCallbackPopdown calls XtPopdown with the specified shell_widget and
65       then calls XtSetSensitive to resensitize the enable_widget.
66
67       If a shell name is not given, XtMenuPopdown calls XtPopdown with the
68       widget for which the translation is specified.  If a shell_name is
69       specified in the translation table, XtMenuPopdown tries to find the
70       shell by looking up the widget tree starting at the parent of the wid‐
71       get in which it is invoked.  If it finds a shell with the specified
72       name in the pop-up children of that parent, it pops down the shell;
73       otherwise, it moves up the parent chain as needed.  If XtMenuPopdown
74       gets to the application top-level shell widget and cannot find a match‐
75       ing shell, it generates an error.
