            Syntax
            CW_LIGHT_EDITOR_SET, WidgetID [, /DIRECTION_DISABLED] [, /DRAG_EVENTS] [, /HIDE_DISABLED] [, LIGHT=objref(s)] [, /LOCATION_DISABLED] [, /TYPE_DISABLED] [, XSIZE=pixels] [, YSIZE=pixels] [, XRANGE=vector] [, YRANGE=vector] [, ZRANGE=vector]
            Arguments
            WidgetID 
            The widget ID of the CW_ LIGHT_EDITOR compound widget.
            Keywords
            DIRECTION_DISABLED
            Set this keyword to make the direction widget portion of the compound widget unchangeable by the user. It will appear insensitive and will not generate an event.
            DRAG_EVENTS
            Set this keyword to cause events to be generated continuously while a slider in the compound widget is being dragged or when the mouse cursor is being dragged across the draw widget portion of the compound widget.
            When this keyword is set, a large number of events can be generated. On slower machines, poor performance can result. Therefore, this option should only be used when detailed or truly interactive control is required.
            Note: Under Microsoft Windows, sliders do not generate these events, but behave just like regular sliders.
            HIDE_DISABLED
            Set this keyword to make the hide widget portion of the compound widget unchangeable by the user. It will appear insensitive and will not generate an event.
            LIGHT
            Set this keyword to one or more object references to IDLgrLight to edit. This will replace the current set of lights being edited with the list of lights from this keyword.
            LOCATION_DISABLED
            Set this keyword to make the location widget portion of the compound widget unchangeable by the user. It will appear insensitive and will not generate an event.
            TYPE_DISABLED
            Set this keyword to make the light type widget portion of the compound widget unchangeable by the user. It will appear insensitive and will not generate an event.
            XRANGE
            A two-element vector defining the data range in the x direction. This keyword is used to determine the valid range for the light's location and direction properties.
            XSIZE
            The width of the drawable area in pixels.
            YRANGE
            A two-element vector defining the data range in the y direction. This keyword is used to determine the valid range for the light's location and direction properties.
            YSIZE
            The height of the drawable area in pixels.
            ZRANGE
            A two-element vector defining the data range in the z direction. This keyword is used to determine the valid range for the light's location and direction properties.
