Detailed Description
The SoTransformBoxDragger provides a box which can be translated, scaled and rotated.
Here's how the dragger looks with its default geometry in the inactive state:
Translate the dragger by clicking and dragging any of the (invisible) sides. Scaling is done by dragging
the corner cubes. Only uniform scaling is supported. Rotation is done by dragging any of the 12 beams
connecting the corner cubes.
This dragger consists of a rigid framework for doing all the usual interaction operations on scene
geometry. The 'user interface' of the dragger is very simple, providing little room for the end-user to
make mistakes.
For the application programmer's convenience, the Coin library also provides a manipulator class called
SoTransformBoxManip, which wraps the SoTransformBoxDragger into the necessary mechanisms for making
direct insertion of this dragger into a scenegraph possible with very little effort.

SoTransformBoxDragger::~SoTransformBoxDragger (void) [protected], [virtual]
Protected destructor.
(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when
their reference count goes to 0.)
Member Function Documentation
SoType SoTransformBoxDragger::getTypeId (void) const [virtual]
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:
void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}
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.
Reimplemented from SoDragger.
const SoFieldData * SoTransformBoxDragger::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are
present, returns NULL.
Reimplemented from SoDragger.
const SoNodekitCatalog * SoTransformBoxDragger::getNodekitCatalog (void) const [virtual]
Returns the nodekit catalog which defines the layout of this class' kit.
Reimplemented from SoDragger.
SbBool SoTransformBoxDragger::setUpConnections (SbBoolonoff, SbBooldoitalways = FALSE) [protected],
[virtual]
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.
void SoTransformBoxDragger::setDefaultOnNonWritingFields (void) [protected], [virtual]
(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:
1. field value is NULL and part is NULL by default
2. it is a leaf SoGroup or SoSeparator node with no children
3. it is a leaf listpart with no children and an SoGroup or SoSeparator container
4. 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.

This field is continuously updated to contain the rotation of the dragger's box.
SoSFVec3f SoTransformBoxDragger::translation
The dragger's offset position from the local origo.
SoSFVec3f SoTransformBoxDragger::scaleFactor
Continuously updated to contain the current vector of scaling along the X, Y and Z axes. The three
