Detailed Description

The SoHandleBoxDragger class provides support for interactive scaling and translation.

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.

SoHandleBoxDragger::~SoHandleBoxDragger (  )  [protected]

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::initClass(). Reimplemented from SoDragger.

SbBool SoHandleBoxDragger::setUpConnections (  SbBool onoff, SbBool doitalways = 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 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.) A virtual method that should call SoField::setDefault() with argument TRUE on part fields that should not be written upon scenegraph export operations. This is typically done when: field value is NULL and part is NULL by default it is a leaf SoGroup or SoSeparator node with no children it is a leaf listpart with no children and a SoGroup or SoSeparator container 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 SoHandleBoxDragger::startCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoHandleBoxDragger::motionCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoHandleBoxDragger::finishCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoHandleBoxDragger::metaKeyChangeCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoHandleBoxDragger::fieldSensorCB (  void * d, SoSensor * s )  [static, protected]

For internal use only. Reimplemented from SoInteractionKit.

void SoHandleBoxDragger::valueChangedCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoHandleBoxDragger::dragStart (  void )  [protected]

For internal use only.

void SoHandleBoxDragger::drag (  void )  [protected]

For internal use only.

void SoHandleBoxDragger::dragFinish (  void )  [protected]

For internal use only.

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]

For internal use only.

SoFieldSensor * SoHandleBoxDragger::scaleFieldSensor [protected]

For internal use only.
