Detailed Description
The SoScaleUniformDragger class provides a mechanism for the end-user
to scale in three 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
simultaneously along all the axes.
Scaling with this dragger can only be done in a uniform manner, ie the
X, Y and Z components of the SoScaleUniformDragger::scaleFactor will
always be exactly equal.

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

SoScaleUniformDragger::~SoScaleUniformDragger (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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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 SoScaleUniformDragger::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.
