This dragger is well suited to use for setting up the fields of a SoDirectionalLight node, as it provides geometry for the end-user to interact with a directional vector.
For convenience, this dragger also by default contains interaction geometry for placing the dragger itself. (SoDirectionalLight nodes don't have a position field, so this was strictly not needed.)
The Coin library also includes a manipulator class, SoDirectionalLightManip, which wraps the functionality provided by this class inside the necessary mechanisms for connecting it to SoDirectionalLight node instances in a scenegraph.
|
Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry. |
|
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::initClass(). 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.)

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 SoDirectionalLight node (unless using the SoDirectionalLightManip 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 SoDirectionalLight node specifically. |
|
Continuously updated to contain the current translation from the dragger's local origo position. This field is not used by the SoDirectionalLightManip, but may be of interest for the application programmer wanting to use the SoDirectionalLightDragger outside the context of controlling a directional light node. |
