NAME

       XmHierarchy — The Hierarchy widget class "XmHierarchy" "Hierarchy" "hierarchy"

SYNOPSIS

       #include <Xm/Hierarchy.h>

DESCRIPTION

       The  Hierarchy widget is not intended to be instantiated itself, but rather should be used
       as the base class for any widget that would like to present a hierarchy of information  to
       the  user  that  is different for the actual widget instance hierarchy of the application.
       This base class is currently used for two widgets  in  the  Motif  widget  set,  Tree  and
       Outline, giving those two widgets a very similar API.

       Note:  The  Hierarchy  widget  assumes that it will be totally responsible for mapping and
       unmapping its children.  Therefore  no  child  of  this  widget  should  ever  modify  its
       mappedWhenManaged  resource.  If  a  child  does  modify  this  resource  the  behavior is
       undefined.

   Classes
       Hierarchy inherits behaviour, resources,  and  traits  from  Core,  Composite,  Composite,
       Constraint, and XmManager classes.

       The class pointer is xmHierarchyWidgetClass.

       The class name is XmHierarchy.
