DESCRIPTION

       This class is used to edit an SoDirectionalLight node (color, intensity, and direction are changed). In addition to directly editing direc-
       tional light nodes, the editor can also be used with callbacks which will be called whenever the light is changed. The  component  consists
       of  a render area and a value slider in the main window, with controls to display a color picker. In the render area there appears a sphere
       representing the world, and a directional light manipulator representing the direction of the light. Picking on the manipulator and  moving
       the  mouse  provides direct manipulation of the light direction. The color picker is used to edit the color, and the value slider edits the
       intensity.

       The editor can currently be attached to only one light at a time. Attaching to two different lights will automatically detach the first one
       before attaching the second.

METHODS

				 SoXtDirectionalLightEditor(Widget parent = NULL, const char *name = NULL, SbBool buildInsideParent = TRUE)
				 ~SoXtDirectionalLightEditor()
	  Constructor and destructor.

     void			 attach(SoPath *pathToLight)
     void			 detach()
	  Attach/detach the editor to/from a directional light. When attached, changes made in the editor directly affect the attached light.

     SbBool			 isAttached()
	  Returns TRUE if the editor is attached.

     void			 addLightChangedCallback(SoXtDirectionalLightEditorCB *f, void *userData = NULL)
     void			 removeLightChangedCallback(SoXtDirectionalLightEditorCB *f, void *userData = NULL)
	  Additional way of using the directional light editor, by registering a callback and setting the light.

     void			 setLight(const SoDirectionalLight &newLight)
     const SoDirectionalLight &  getLight() const
	  Set new light values, and get the current light values.
