Specifies a Boolean value that indicates the new value of the map_when_managed
field.
w
Specifies the widget.
Description
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.
