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 eli‐
       gible 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 ances‐
       tors are realized, managed, and (except for gadgets) mapped.  Some part
       of the widget's rectangular area is unobscured by the  widget's	ances‐
       tors,  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 eli‐
       gible to receive focus if it meets the  conditions  above  and  has  no
       child  whose  XmNtraversalOn resource is True.  Specifies the ID of the
       widget

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