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.
Constructor & Destructor Documentation
SoHandleBoxDragger::SoHandleBoxDragger (void)Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.
Node kit structure (new entries versus parent class marked with arrow prefix):

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.
References SoFieldSensor::attach(), SoBaseKit::connectionsSetUp, SoFieldSensor::detach(), fieldSensorCB(), SoFieldSensor::getAttachedField(), scaleFactor, scaleFieldSensor, SoInteractionKit::setUpConnections(), translation, and translFieldSensor.
Referenced by SoHandleBoxDragger().
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.
