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:

 Screen Shot of Default Dragger

A handle box 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 (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

  SoType SoHandleBoxDragger::getClassTypeId (void) [static]
This static method returns the SoType object associated with objects of this class.

  SoType SoHandleBoxDragger::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting.

Reimplemented from SoDragger.

  const SoFieldData ** SoHandleBoxDragger::getFieldDataPtr (void) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
 Returns the SoFieldData class which holds information about fields in this node.

  const SoFieldData * SoHandleBoxDragger::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoDragger.

  const SoNodekitCatalog * SoHandleBoxDragger::getClassNodekitCatalog (void) [static]
Returns the nodekit catalog which defines the layout of this class' kit.

  const SoNodekitCatalog * SoHandleBoxDragger::getNodekitCatalog (void) const [virtual]
Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

  const SoNodekitCatalog ** SoHandleBoxDragger::getClassNodekitCatalogPtr (void) [static], [protected]
Returns the pointer to the pointer of the nodekit catalog for this class.

  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().

  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.)

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 scene graph 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 is 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.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

  void SoHandleBoxDragger::dragStart (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 dragger is selected (picked) by the user.

  void SoHandleBoxDragger::drag (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 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 deactivate 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.
