Detailed Description
The SoHandleBoxDragger class provides support for interactive scaling
and translation.
Here’s how the dragger looks with its default geometry in the inactive
state:
A handlebox dragger is convenient to use for letting the user interact
with geometry that can be scaled (uniformly or in a non-uniform way)
and translated in 3D.
The dragger consists of a ’cube’ of interaction geometry. The end-user
can click and drag any side of the cube to translate the dragger and
click and drag any of the corner or edge markers for scaling
operations.

SoHandleBoxDragger::~SoHandleBoxDragger (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 SoHandleBoxDragger::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 SoHandleBoxDragger::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 SoHandleBoxDragger::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.

considered internal to the library, as it is not likely to be of
interest to the application programmer.
Called when user drags the mouse after picking the dragger.
void SoHandleBoxDragger::dragFinish (void) [protected] This API member is
considered internal to the library, as it is not likely to be of
interest to the application programmer.
Called when mouse button is released after picking and interacting with
the dragger.
void SoHandleBoxDragger::setAllPartsActive (SbBool onoroff) [protected]
Activate or deactive all dragger geometry parts.
Member Data Documentation
SoSFVec3f SoHandleBoxDragger::scaleFactor Continuously updated to contain
the current vector of scaling along the X, Y and Z axes.
SoSFVec3f SoHandleBoxDragger::translation 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.
SoFieldSensor * SoHandleBoxDragger::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 * SoHandleBoxDragger::scaleFieldSensor [protected] This API
member is considered internal to the library, as it is not likely to be
of interest to the application programmer.
