Detailed Description
The SoTabBoxDragger wraps a box around geometry you can then translate
and scale.
Here’s how the dragger looks with its default geometry in the inactive
state:
This dragger lets the end-user do translation and non-uniform scaling
of geometry with an easy to understand interface.
Click and drag any side of the box to translate (hold down a SHIFT key
to lock to one axis) and click and drag any of the tab markers in the
corners to scale. The way the different tabs influences the scale
operation should be straight-forward and intuitive to the end-user.
The SoTabBoxDragger is a composite dragger, implemented with 6
SoTabPlaneDragger instances set up as the sides of a box.
Constructor & Destructor Documentation
SoTabBoxDragger::SoTabBoxDragger (void) Default constructor, sets up the
dragger nodekit catalog with the interaction and feedback geometry.

SoTabBoxDragger::~SoTabBoxDragger (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 SoTabBoxDragger::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.
void SoTabBoxDragger::adjustScaleTabSize (void) Signals the dragger to
recalculate the size of its tabs.
Simply calls SoTabPlaneDragger::adjustScaleTabSize() for all 6 planes
this dragger consists of.
SbBool SoTabBoxDragger::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 SoTabBoxDragger::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 SoTabBoxDragger::invalidateSurroundScaleCB (void * d, SoDragger * d)
[static, protected] surroundScale is invalidated every time a child
dragger is activated/deactivated using this callback
void SoTabBoxDragger::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 SoTabBoxDragger::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
SoSFVec3f SoTabBoxDragger::translation Continuously updated to contain the
current translation from the dragger’s local origo position.
SoSFVec3f SoTabBoxDragger::scaleFactor Continuously updated to contain the
current vector of scaling along the X, Y and Z axes.
SoFieldSensor * SoTabBoxDragger::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 * SoTabBoxDragger::scaleFieldSensor [protected] This API
member is considered internal to the library, as it is not likely to be
of interest to the application programmer.
