The SoDragger class is the base class for all draggers.
Draggers is a mechanism used for letting the end-users of your application code interact with elements in 3D, by scaling, rotating or translating geometry or other instances in the scene (like cameras or lightsources).
For a very thorough introduction and tutorial to the dragger classes and general concepts, we advise you to consult «The Inventor Mentor», ISBN 0-201-62495-8, chapter 15.
This is the common superclass for all dragger classes.
It holds the current motion matrix, and offers lots of convenience methods to build from for it's subclasses – that is, the non-abstract dragger classes to use as nodes in your scenegraph.
The motion matrix is used to modify the model matrix during traversal, and this is a common dragger mechanism – all draggers should update this during dragging.
A number of the Coin dragger classes have built-in convenience wrapper classes, called manipulators. See for instance the SoTrackballDragger / SoTrackballManip pair.
The matching manipulator class for any dragger class has basically two convenient additions to the functionality of the stand-alone dragger: 1) it makes swapping the dragger in and out of the scenegraph very straightforward (something which is often done for draggers in 3D user interfaces), 2) it wraps up the dragger with SoSurroundScale and SoAntiSquish nodes where applicable, so the dragger geometry automatically scales up or down to match the geometry it influences.
This last functionality can also be duplicated in a rather straightforward manner outside of the context of a manipulator, as can be seen from the usage example in the SoSurroundScale class documentation.
The appearance of draggers can be modified by either using the SoDragger::setPart() method (see usage example below) or by setting up external Inventor-format files which the geometry parts are read from. The latter method can be done by setting the environment variable SO_DRAGGER_DIR
to point to a directory with replacement geometry files. The name of the new files and the name of the nodes / sub-graphs with the replacement geometries must follow a rigid scheme. We advise you to look at the Coin sourcecode directory Coin/data/draggerDefaults/ to see how the replacement geometry files should be named. Setting SO_DRAGGER_DIR
to this directory and modifying the files there provides a convenient way to play around with new dragger geometry arrangements.
As mentioned above, SoDragger::setPart() can be used to modify the appearance of a dragger by changing it's default geometry. One common technique is for instance to take advantage of this to use only parts of a dragger, by replacing / disabling the geometry that you don't want the end-user to interact with. The following code example shows how to remove the translation functionality of the SoTransformBoxDragger:
Draggers are also node kits, and below is the catalog structure for this top-level dragger class.
Node kit structure (new entries versus parent class marked with arrow prefix):
CLASS SoDragger -->"this" "callbackList" "topSeparator" --> "motionMatrix" "geomSeparator"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:
CLASS SoDragger PVT "this", SoDragger --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- PVT "motionMatrix", SoMatrixTransform --- PVT "geomSeparator", SoSeparator ---
(See SoBaseKit::printTable() for information about the output formatting.)
Holds various settings for projectors, which might affect cylindrical and spherical based draggers. Specifies whether dragging should be based on the front or back of the sphere / cylinder, or if the picked point should be used to decide this.

FRONT | Always use front of projector. |
BACK | Always use back of projector. |
USE_PICK | Use picked point to decide front or back of projector. |

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.
Usage example:
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

(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 is a virtual method, and the code in it should call SoField::setDefault() with argument TRUE
on part fields that should not be written upon scenegraph export operations.
This is typically done when:
field value is NULL
and part is NULL
by default
it is a leaf SoGroup or SoSeparator node with no children
it is a leaf listpart with no children and an SoGroup or SoSeparator container
it is a non-leaf part and it's of SoGroup type and all fields are at their default values
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.
