Detailed Description
The SoRotateCylindricalDragger class is for rotating geometry around a single axis.
Here's how the dragger looks with its default geometry in the inactive state:.
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.
For the dragger orientation and positioning itself, use some kind of transformation node in your scenegraph, as usual.
Constructor & Destructor Documentation
SoRotateCylindricalDragger::SoRotateCylindricalDragger (void)Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.
Node kit structure (new entries versus parent class marked with arrow prefix):
CLASS SoRotateCylindricalDragger -->"this" "callbackList" "topSeparator" "motionMatrix" "geomSeparator" --> "rotatorSwitch" --> "rotator" --> "rotatorActive" --> "feedbackSwitch" --> "feedback" --> "feedbackActive" .fi (See SoBaseKit::printDiagram() for information about the output formatting.) Detailed information on catalog parts: CLASS SoRotateCylindricalDragger PVT "this", SoRotateCylindricalDragger --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- PVT "motionMatrix", SoMatrixTransform --- PVT "geomSeparator", SoSeparator --- PVT "rotatorSwitch", SoSwitch --- "rotator", SoSeparator --- "rotatorActive", SoSeparator --- PVT "feedbackSwitch", SoSwitch --- "feedback", SoSeparator --- "feedbackActive", SoSeparator --- .fi (See SoBaseKit::printTable() for information about the output formatting.)

SoRotateCylindricalDragger::~SoRotateCylindricalDragger () [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 SoRotateCylindricalDragger::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().
Reimplemented from SoDragger.
void SoRotateCylindricalDragger::setProjector (SbCylinderProjector * p)Replace the default cylinder projection strategy. You may want to do this if you change the dragger geometry, for instance.
The default cylinder projection is an SbCylinderPlaneProjector.

- SbCylinderSectionProjector, SbCylinderSheetProjector
References cylinderProj, and userProj.
const SbCylinderProjector * SoRotateCylindricalDragger::getProjector (void) constReturns projector instance used for converting from user interaction dragger movements to 3D dragger re-orientation.
See also:
- setProjector()
References cylinderProj.
SbBool SoRotateCylindricalDragger::setUpConnections (SbBool onoff, SbBool doitalways = 0) [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.)

Member Data Documentation
SoSFRotation SoRotateCylindricalDragger::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.
