Detailed Description

The SoTranslate2Dragger class provides a mechanism for the end-user to translate in a plane.

Use this dragger to allow the end-user of your application to translate along the X-axis and the Y-axis at the same time, ie freely inside a 3D plane. (Use a transformation node in front of the dragger to position it and re-orient it to translate in any plane.)

By holding down a SHIFT key, the end-user can temporarily constrain the dragger to a single one of the two axes.

Constructor & Destructor Documentation

SoTranslate2Dragger::SoTranslate2Dragger (  void )

Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.

SoTranslate2Dragger::~SoTranslate2Dragger (  )  [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 SoTranslate2Dragger::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 SoTranslate2Dragger::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 SoTranslate2Dragger::startCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoTranslate2Dragger::motionCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoTranslate2Dragger::finishCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoTranslate2Dragger::metaKeyChangeCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoTranslate2Dragger::fieldSensorCB (  void * d, SoSensor * s )  [static, protected]

For internal use only. Reimplemented from SoInteractionKit.

void SoTranslate2Dragger::valueChangedCB (  void * f, SoDragger * d )  [static, protected]

For internal use only.

void SoTranslate2Dragger::dragStart (  void )  [protected]

For internal use only.

void SoTranslate2Dragger::drag (  void )  [protected]

For internal use only.

void SoTranslate2Dragger::dragFinish (  void )  [protected]

For internal use only.

Member Data Documentation

SoSFVec3f SoTranslate2Dragger::translation

Continuously updated to contain the current translation from the dragger's local origo position. Only the first two components (the X and Y values) can be changed by the end-user. 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 * SoTranslate2Dragger::fieldSensor [protected]

For internal use only. Reimplemented from SoInteractionKit.

SbVec3f SoTranslate2Dragger::worldRestartPt [protected]

For internal use only.

SbPlaneProjector * SoTranslate2Dragger::planeProj [protected]

The SbPlaneProjector instance used for projecting from 2D mouse cursor positions to 3D points.
