Detailed Description
The SoScale2Dragger class provides a mechanism for the end-user to
scale in two dimensions.
Here’s how the dragger looks with its default geometry in the inactive
state:
Use this dragger to allow the end-user of your application to scale
along the X-axis and the Y-axis. (Use a transformation node in front of
the dragger to position it and re-orient it to scale in any plane.)
Scaling can be done in a non-uniform manner.

Constructor & Destructor Documentation
SoScale2Dragger::SoScale2Dragger (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 SoScale2Dragger
-->"this"
"callbackList"
"topSeparator"
"motionMatrix"
"geomSeparator"
--> "scalerSwitch"
--> "scaler"
--> "scalerActive"
--> "feedbackSwitch"
--> "feedback"
--> "feedbackActive"
.fi
(See SoBaseKit::printDiagram() for information about the output formatting.)

SoScale2Dragger::~SoScale2Dragger (void) [protected, virtual] 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 SoScale2Dragger::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.
SbBool SoScale2Dragger::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.
void SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::finishCB (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 SoScale2Dragger::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.
Reimplemented from SoInteractionKit.
void SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::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 SoScale2Dragger::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
SoSFVec3f SoScale2Dragger::scaleFactor Continuously updated to contain the
current vector of scaling along the X, Y and Z axes.
For the SoScale2Dragger, only the X and Y components are used, the Z
component will always be equal to 1 (ie no scaling).
SoFieldSensor * SoScale2Dragger::fieldSensor [protected] This API member is
considered internal to the library, as it is not likely to be of
interest to the application programmer.
Reimplemented from SoInteractionKit.
SbPlaneProjector * SoScale2Dragger::planeProj [protected] This API member
is considered internal to the library, as it is not likely to be of
interest to the application programmer.
