Here's how the dragger looks with it's default geometry in the inactive state:
Translation is done with this dragger by picking the flat transparent box ("x-z" translation) or the solid middle part of the axis ("y"-axis translation). Press a SHIFT-key while translating in x-z to constrain to one of the principal axes.
Uniform scale operations can be done by dragging any of the 6 cubes. Non-uniform scale operations can not be done with this dragger.
Rotations are invoked by clicking and dragging the line parts of the 3 principal "axes" of the dragger geometry.
An "action shot" of the SoJackDragger used within an SoClipPlaneManip:
The name "Jack dragger" probably stems from this dragger being implemented by SGI for interacting with a "jack-in-the-box" type model way back in the Inventor history.
For programmer convenience, this dragger comes fully wrapped within instances of the SoJackManip class. The SoClipPlaneManip manipulator also uses this dragger, for controlling an SoClipPlane node.

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. |
|
Used to invalidate the surroundScale and antiSquish parts when a child dragger starts or finishes dragging. |
|
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 rotation of the current direction vector of the dragger. |
|
Continuously updated to contain the current translation from the dragger's local origo position. The application programmer applying this dragger in his code should connect the relevant node fields in the scene to this field to make it follow the dragger. |
|
Continuously updated to contain the current vector of scaling along the X, Y and Z axes. Only uniform scaling can be done with the SoJackDragger, so the 3 vector components will always be equal. |
