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
void SoTransformBoxDragger::initClass (void) [static] 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.
SbBool SoTransformBoxDragger::setUpConnections (SbBool onoff, SbBool
doitalways = 0) [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.
Reimplemented from SoDragger.
void SoTransformBoxDragger::invalidateSurroundScaleCB (void * f, SoDragger
* d) [static, protected] This API member is considered internal to the
library, as it is not likely to be of interest to the application
programmer.
void SoTransformBoxDragger::fieldSensorCB (void * d, SoSensor * s) [static,
protected] 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.
void SoTransformBoxDragger::valueChangedCB (void * f, SoDragger * d)
[static, protected] This API member is considered internal to the
library, as it is not likely to be of interest to the application
programmer.
Member Data Documentation
SoSFRotation SoTransformBoxDragger::rotation 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 components will always be equal, as this dragger only supports
uniform scale operations.
SoFieldSensor * SoTransformBoxDragger::rotFieldSensor [protected] This API
member is considered internal to the library, as it is not likely to be
of interest to the application programmer.
SoFieldSensor * SoTransformBoxDragger::translFieldSensor [protected] This
API member is considered internal to the library, as it is not likely
to be of interest to the application programmer.
SoFieldSensor * SoTransformBoxDragger::scaleFieldSensor [protected] This
API member is considered internal to the library, as it is not likely
to be of interest to the application programmer.
