Here's how the dragger looks with it's default geometry in the inactive state:
This dragger is well suited for setting up the fields of a SoSpotLight node, as it provides geometry for the end-user to interact with a directional vector for the spotlight, to set up it's position and to control the cut-off angle for the "lampshade" around the lightsource.
Note that there is one aspect of SoSpotLight nodes that can not be controlled with this dragger: the SoSpotLight::dropOffRate field.
The Coin library includes a manipulator class, SoSpotLightManip, which wraps the functionality provided by this class inside the necessary mechanisms for connecting it to SoSpotLight node instances in a scenegraph.

Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry. Node kit structure (new entries versus parent class marked with arrow prefix):

(See SoBaseKit::printTable() for information about the output formatting.) |
|
Protected destructor. (Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.) |
|
Initializes type system for this dragger class. Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init(). Reimplemented from SoDragger. |
|
Sets up all internal connections for instances of this class. (This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.) Reimplemented from SoInteractionKit. |
|
(Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed are writing extensions, see the information in the SoBaseKit class documentation.)
A virtual method that should call SoField::setDefault() with argument This is typically done when:
Subclasses should usually override this to do additional settings for new member fields. From the subclass, do remember to call "upwards" to your superclass' setDefaultOnNonWritingFields() method. Reimplemented from SoDragger. |

|
Scales the geometry representing the "lampshade" around the lightsource to represent the given beamangle. |
|
This field is continuously updated to contain the rotation of the current direction vector. The application programmer will typically connect this to the rotation field of a SoSpotLight node (unless using the SoSpotLightManip class, where this is taken care of automatically). It may also of course be connected to any other rotation field controlling the direction of scenegraph geometry, it does not have to part of a SoSpotLight node specifically. |
|
Continuously updated to contain the current translation from the dragger's local origo position. |
|
The cut-off angle for the "lampshade" around the lightsource. Typically connected to a SoSpotLight::cutOffAngle field. |
