XtMapWidget, XtSetMappedWhenManaged,
XtUnmapWidget - map and unmap widgets 
- int XtMapWidget(Widget w); 
- void XtSetMappedWhenManaged(Widget w, Boolean map_when_managed);  
- int XtUnmapWidget(Widget
w);  
Specifies a Boolean value that indicates the new value of
the map_when_managed  field. 
Specifies the widget. 
If the widget
is realized and managed and if the new value of map_when_managed is  True,
  XtSetMappedWhenManaged   maps the window. If the widget is realized and
managed and if the new value of map_when_managed is  False,   it unmaps
the window. XtSetMappedWhenManaged   is a convenience function that is equivalent
to (but slightly faster than) calling XtSetValues   and setting the new
value for the mappedWhenManaged resource. As an alternative to using XtSetMappedWhenManaged
  to control mapping, a client may set mapped_when_managed to False   and
use XtMapWidget   and XtUnmapWidget   explicitly.
