Here's how the dragger looks with it's default geometry in the inactive state:
This dragger is well suited to use for setting up the fields of a SoPointLight node, as it provides geometry for the end-user to translate a point in 3D space.
The Coin library also includes a manipulator class, SoPointLightManip, which wraps the functionality provided by this class inside the necessary mechanisms for connecting it to SoPointLight 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):

|
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. |

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Reimplemented from SoInteractionKit. |
|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. |
|
This field is continuously updated to contain the translation of the pointlight dragger. The application programmer will typically connect this to the SoPointLight::location field of a SoPointLight node (unless using the SoPointLightManip class, where this is taken care of automatically). It may also of course be connected to any other location / translation field controlling the position of scenegraph geometry, it does not have to part of a SoPointLight node specifically. |
