DXmHelpOnContext(3X)					  DXmHelpOnContext(3X)

       DXmHelpOnContext	 -  Enters the application into context sensitive help
       mode and either calls a help callback (if one exists) or	 searches  for
       one in the widget's parent.

       void DXmHelpOnContext(
	       Widget widget,
	       Boolean confine );

       The  identifier	of the widget (widget ID) to pass to the XmTrackingLo‐
       cate routine.  A Boolean value passed to XmTrackingLocate.  When	 True,
       confines	 the  help  cursor  (?)	 to the widget specified in the widget

       The DXmHelpOnContext routine enters context sensitive help mode, chang‐
       ing the cursor to the help cursor (?) and then waiting for an MB1 click
       on a widget.  If the selected widget has a  help	 callback,  that  help
       callback	 is  called;  otherwise,  the widget's parent is checked for a
       help callback.

       Note that a Null callback structure pointer is passed to the help call‐
       back.   Therefore,  help	 callbacks in your application should test the
       value of this pointer before they attempt to use it.
