NAME

       XmGetFocusWidget -- Returns the ID of the widget that has keyboard focus

SYNOPSIS

       #include <Xm/Xm.h>
       Widget XmGetFocusWidget(
       Widget widget);

DESCRIPTION

       XmGetFocusWidget  examines  the	hierarchy that contains the specified widget and returns the ID of the widget that has keyboard focus. The
       function extracts the widget ID from the associated Shell widget; therefore, the specified widget can be located anywhere in the hierarchy.

       widget	 Specifies a widget ID within a given hierarchy

RETURN

       Returns the ID of the widget with keyboard focus. If no child of the Shell has focus, the function returns NULL.

NAME

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

SYNOPSIS

       #include <Xm/Xm.h>
       Boolean XmIsTraversable(
       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:

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

	  o  The widget and its ancestors are realized, managed, and (except for gadgets) mapped.  If an application unmaps a widget that has  its
	     XmNmappedWhenManaged resource set to True, the return value is undefined.

	  o  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 eli-
       gible to receive focus if it meets the conditions above and has no child whose XmNtraversalOn resource is True.

       Note that when all widgets in a shell hierarchy have been made untraversable, they are considered to have lost focus. When a widget in this
       hierarchy is made traversable again, it regains focus.

       XmIsTraversable may return unexpected results when widget or its ancestors are overlapped by their siblings.

       widget	 Specifies the ID of the widget

RETURN

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