.SH DESCRIPTION
\*(CbSoSpotLightDragger\f1 is a composite dragger. It is shaped like a beam of light emanating from a sun-like ball. An arrow runs along the axis of the beam and extends past the end of the beam. 
.sp
When you click and drag the beam,
\&it opens and closes with an umbrella-like motion. The angle between the center and edge of the beam is stored in the \*(Cbangle\f1 field of this dragger; setting the \*(Cbangle\f1 field causes the beam to widen or narrow in response.
\&The spotlight dragger does not use a standard dragger class to execute this motion. More details are given later in this section. 
.sp
Dragging the arrow rotates it arount the sun, and the beam moves with
\&it. The arrow is an \*(CbSoRotateSphericalDragger\f1 that controls the \*(Cbrotation\f1 field. See the reference page for \*(CbSoDirectionalLightDragger\f1, which works the same way, for details. 
.sp
The sun-shape can be dragged to translate all three pieces together through 3-space.
\&Its movement controls the \*(Cbtranslation\f1 field and works exactly as described in the reference pages for \*(CbSoDirectionalLightDragger\f1 and \*(CbSoPointLightDragger\f1 (which goes into more detail). 
.sp
\f2Remember:\f1 This is \f2not\f1 a light source! It just looks like one. If you want to move
\&a light with this dragger, you can do the following: 
.sp
[a] Use an \*(CbSoSpotLightManip\f1, which is subclassed from \*(CbSoLight\f1. It creates an \*(CbSoSpotLightDragger\f1 and uses it as the interface to change the \*(Cblocation\f1, \*(Cbdirection\f1, and \*(CbcutOffAngle\f1 of its light source (see the \*(CbSoSpotLightManip\f1 man page).
\&The manip also edits the \*(Cbmaterial\f1 part of this dragger to match the color of light the manip is producing. 
.sp
[b] Connect the \*(Cbangle\f1 field of this dragger to the \*(CbcutOffAngle\f1 field of an \*(CbSoSpotLight\f1 with a field-to-field connection. 
.sp
See the \*(CbSoPointLightDragger\f1
\&and \*(CbSoDirectionalLightDragger\f1 man pages for other ways to control light parameters with the \*(Cbrotation\f1 and \*(Cbtranslation\f1 fields. 
.sp
This class creates its own projector and handles mouse events to do it's own dragging of the beam angle. When the mouse
\&picks a point on the beam, that point is dragged in a circle just like in an \*(CbSoRotateDiscDragger\f1, but the plane of the disc is re-defined every time a drag is initiated. Imagine placing the metal tip of a compass at the
\&apex of the cone and the pencil tip at the picked point. If you swing an arc through the central axis of the cone, you will be drawing the arc used to drag the beam open and closed. 
.sp
The beam is opened
\&and closed not by rotating, but by scaling. The dragger scales the beam-cone so that the height and radius change to move the picked point along the circle. Then the \*(Cbangle\f1 field is calculated from the
\&height and radius. 
.sp
You can change the geometry of parts in any instance of this dragger using \*(CbsetPart()\f1. The default part geometries are defined as resources for this \*(CbSoSpotLightDragger\f1 class. They are detailed below in the \*(CrDRAGGER RESOURCE\f1
\&section. You can make your program use different default resources for the parts by copying the file \*(Cb/usr/share/data/draggerDefaults/spotLightDragger.iv\f1 into your own directory, editing the file, and then setting the environment variable \*(CbSO_DRAGGER_DIR\f1 to be a path
\&to that directory.
