Detailed DescriptionThe SoRotateDiscDragger class is for rotating geometry around a single axis. Here's how the dragger looks with its default geometry in the inactive state:
Screen Shot of Default Dragger Use an instance of this dragger class in your scenegraph to let the end-users of your application rotate geometry around a pre-defined axis vector in 3D. The special feature of this dragger that sets it apart from the other draggers that provides rotation around an axis (like the SoRotateCylindricalDragger) is that it provides a convenient interface to rotate around an axis that is pointing in approximately the same direction as the camera. This is useful for interacting with for instance something like a 'volume' knob. For the dragger orientation and positioning itself, use some kind of transformation node in your scenegraph, as usual.

Member Function Documentation
SoType SoRotateDiscDragger::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 SoDragger.
const SoFieldData * SoRotateDiscDragger::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 * SoRotateDiscDragger::getNodekitCatalog (void) const [virtual]Returns the nodekit catalog which defines the layout of this class' kit. Reimplemented from SoDragger.
SbBool SoRotateDiscDragger::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 SoRotateDiscDragger::startCB (void * f, SoDragger * d) [static], [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoRotateDiscDragger::motionCB (void * f, SoDragger * d) [static], [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoRotateDiscDragger::doneCB (void * f, SoDragger * d) [static], [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoRotateDiscDragger::fieldSensorCB (void * d, SoSensor * s) [static], [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoRotateDiscDragger::valueChangedCB (void * f, SoDragger * d) [static], [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoRotateDiscDragger::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 SoRotateDiscDragger::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 SoRotateDiscDragger::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.
Member Data Documentation
SoSFRotation SoRotateDiscDragger::rotationThis field is continuously updated to contain the rotation of the current direction vector of the dragger. The application programmer using this dragger in his scenegraph should connect the relevant node fields in the scene to this field to make them follow the dragger orientation.
SoFieldSensor * SoRotateDiscDragger::fieldSensor [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
SbPlaneProjector * SoRotateDiscDragger::planeProj [protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
