Detailed Description

The SoVRMLDragSensor class is a superclass for VRML drag sensors.

This class collects the two fields that are common for some of the sensor nodes, plus some common functions for these. Since this is an abstract 'helper' class, it does not represent an actual node from the VRML97 specification, so don't use it as such.

For more information, a detailed discussion of drag sensors is available in section 4.6.7.4 of the VRML97 specification:

http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.7.4.

Constructor & Destructor Documentation

SoVRMLDragSensor::SoVRMLDragSensor (void) [protected]

Constructor.

SoVRMLDragSensor::~SoVRMLDragSensor () [protected], [virtual]

Destructor.

Member Function Documentation

SoType SoVRMLDragSensor::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoVRMLSensor.

Reimplemented in SoVRMLCylinderSensor, SoVRMLPlaneSensor, and SoVRMLSphereSensor.

const SoFieldData * SoVRMLDragSensor::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 SoVRMLSensor.

Reimplemented in SoVRMLCylinderSensor, SoVRMLPlaneSensor, and SoVRMLSphereSensor.

void SoVRMLDragSensor::handleEvent (SoHandleEventAction * action) [virtual]

Action method for SoHandleEventAction.

Inspects the event data from action, and processes it if it is something which this node should react to.

Nodes influencing relevant state variables for how event handling is done also overrides this method.

Reimplemented from SoNode.

SbBool SoVRMLDragSensor::dragStart (void) [protected], [pure virtual]

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.

Implemented in SoVRMLCylinderSensor, SoVRMLPlaneSensor, and SoVRMLSphereSensor.

void SoVRMLDragSensor::drag (void) [protected], [pure virtual]

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.

Implemented in SoVRMLCylinderSensor, SoVRMLPlaneSensor, and SoVRMLSphereSensor.

void SoVRMLDragSensor::dragFinish (void) [protected], [pure virtual]

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.

Implemented in SoVRMLCylinderSensor, SoVRMLPlaneSensor, and SoVRMLSphereSensor.

const SbVec3f & SoVRMLDragSensor::getLocalStartingPoint (void) const [protected]

Returns the interaction starting point.

const SbMatrix & SoVRMLDragSensor::getLocalToWorldMatrix (void) const [protected]

Returns the matrix that transforms to the world coordinate system.

const SbMatrix & SoVRMLDragSensor::getWorldToLocalMatrix (void) const [protected]

Returns the matrix that transforms from the world coordinate system.

const SbViewVolume & SoVRMLDragSensor::getViewVolume (void) const [protected]

Returns the current view volume.

const SbVec2f & SoVRMLDragSensor::getNormalizedLocaterPosition (void) const [protected]

Returns the current normalized pointer position.

Member Data Documentation

SoSFVec3f SoVRMLDragSensor::trackPoint_changed

An event out that is generated when the trackpoint is changed.

SoSFBool SoVRMLDragSensor::autoOffset

When TRUE, the offset field is updated when a dragging sequence is finished. Default value is TRUE.
