Detailed Description
The SoTabPlaneDragger class is a dragger you can translate and scale within a plane.
Here's how the dragger looks with its default geometry in the inactive state:.
For translation, click anywhere inside the dragger's plane and move it about in 2D.
For non-uniform scaling operations, click and drag any of the 4 side tabs. For uniform scaling, click and drag any of the 4 corner tabs.

Constructor & Destructor Documentation
SoTabPlaneDragger::SoTabPlaneDragger (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 SoTabPlaneDragger -->"this" "callbackList" "topSeparator" "motionMatrix" "geomSeparator" --> "planeSwitch" --> "translator" --> "scaleTabs" --> "scaleTabMaterial" --> "scaleTabHints" --> "scaleTabMaterialBinding" --> "scaleTabNormalBinding" --> "scaleTabNormal" --> "edgeScaleCoords" --> "edgeScaleTab0" --> "edgeScaleTab1" --> "edgeScaleTab2" --> "edgeScaleTab3" --> "cornerScaleCoords" --> "cornerScaleTab0" --> "cornerScaleTab1" --> "cornerScaleTab2" --> "cornerScaleTab3" .fi (See SoBaseKit::printDiagram() for information about the output formatting.)

(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 SoTabPlaneDragger::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 SoTabPlaneDragger::adjustScaleTabSize (void)Signals the dragger to recalculate the size of its tabs. This method is not doing anything useful in Coin, since the tab sizes are recalculated every time the dragger is rendered, even though this method has not been called.
void SoTabPlaneDragger::GLRender (SoGLRenderAction * action) [protected, virtual]Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoDragger.
References SoFieldContainer::enableNotify(), SoAction::getState(), SoDragger::GLRender(), and reallyAdjustScaleTabSize().
SbBool SoTabPlaneDragger::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.)
Reimplemented from SoInteractionKit.
References SoFieldSensor::attach(), SoBaseKit::connectionsSetUp, SoFieldSensor::detach(), SoFieldSensor::getAttachedField(), scaleFactor, SoInteractionKit::setUpConnections(), and translation.
Referenced by SoTabPlaneDragger().
void SoTabPlaneDragger::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 scenegraph 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's 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.
References SoDragger::setDefaultOnNonWritingFields().
void SoTabPlaneDragger::reallyAdjustScaleTabSize (SoGLRenderAction * action) [protected]Recalculates the size of the tabs, based on the current view volume, the current viewport, the current model matrix and the current scale factor. If action == NULL, a default size will be used.

Referenced by GLRender(), and SoTabPlaneDragger().
void SoTabPlaneDragger::getXYScreenLengths (SbVec2f & lengths, const SbMatrix & localtoscreen, const SbVec2s & winsize) [protected]Not implemented.
void SoTabPlaneDragger::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.
References SoPath::findNode(), SoDragger::getEvent(), SoDragger::getLocalStartingPoint(), SoDragger::getLocalToWorldMatrix(), SoDragger::getPickPath(), SbString::getString(), SoDragger::getSurrogatePartPickedName(), SbMatrix::multVecMatrix(), SbLineProjector::setLine(), SbPlaneProjector::setPlane(), SbVec3f::setValue(), and SbString::sprintf().
void SoTabPlaneDragger::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.
References SoDragger::appendScale(), SoDragger::appendTranslation(), SbVec3f::dot(), SoDragger::getEvent(), SoDragger::getLocalStartingPoint(), SoDragger::getLocalToWorldMatrix(), SoDragger::getNormalizedLocaterPosition(), SoDragger::getStartMotionMatrix(), SoDragger::getViewVolume(), SoDragger::getWorldToLocalMatrix(), SoDragger::isAdequateConstraintMotion(), SbVec3f::length(), SbMatrix::multVecMatrix(), SbPlaneProjector::project(), SbLineProjector::project(), SoDragger::saveStartParameters(), SoDragger::setMotionMatrix(), SoDragger::setStartingPoint(), SoDragger::setStartLocaterPosition(), SbProjector::setViewVolume(), and SbProjector::setWorkingSpace().
void SoTabPlaneDragger::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.
