NAME
  XmIsTraversable - A function that identifies whether a widget can be
  traversed

SYNOPSIS
  #include <Xm/Xm.h>

  Boolean XmIsTraversable (widget)
	  Widget widget;

DESCRIPTION
  XmIsTraversable determines whether the specified widget is eligible to
  receive focus through keyboard traversal. In general, a widget is eligible
  to receive focus when all of the following conditions are true:

    ·  The widget and its ancestors are not being destroyed, are sensitive,
       and have a value of True for XmNtraversalOn.

    ·  The widget and its ancestors are realized, managed, and (except for
       gadgets) mapped.

    ·  Some part of the widget's rectangular area is unobscured by the
       widget's ancestors, or some part of the widget's rectangular area is
       inside the work window (but possibly outside the clip window) of a
       ScrolledWindow whose XmNscrollingPolicy is XmAUTOMATIC and whose
       XmNtraverseObscuredCallback is not NULL.

  Some widgets may not be eligible to receive focus even if they meet all
  these conditions. For example, most managers cannot receive focus through
  keyboard traversal. Some widgets may be eligible to receive focus under
  particular conditions. For example, a DrawingArea is eligible to receive
  focus if it meets the conditions above and has no child whose
  XmNtraversalOn resource is True.

  widget
      Specifies the ID of the widget

RETURN VALUE
  Returns True if the widget is eligible to receive focus through keyboard
  traversal; otherwise, returns False.
