Detailed Description
The SoScale2UniformDragger 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 with this dragger can only be done in a uniform manner, ie the
X component of the SoScale2UniformDragger::scaleFactor will always
equal the Y component.
For non-uniform scaling operations in 2 dimensions, use the
SoScale2Dragger.

Constructor & Destructor Documentation
SoScale2UniformDragger::SoScale2UniformDragger (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 SoScale2UniformDragger
-->"this"
"callbackList"
"topSeparator"
"motionMatrix"
"geomSeparator"
--> "scalerSwitch"
--> "scaler"
--> "scalerActive"
--> "feedbackSwitch"
--> "feedback"
--> "feedbackActive"
.fi
(See SoBaseKit::printDiagram() for information about the output formatting.)

SoScale2UniformDragger::~SoScale2UniformDragger (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 SoScale2UniformDragger::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 SoScale2UniformDragger::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.

protected] This API member is considered internal to the library, as it
is not likely to be of interest to the application programmer.
void SoScale2UniformDragger::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 SoScale2UniformDragger::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 SoScale2UniformDragger::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 SoScale2UniformDragger::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 SoScale2UniformDragger::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 SoScale2UniformDragger::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 SoScale2UniformDragger::scaleFactor Continuously updated to
contain the current vector of scaling along the X, Y and Z axes.
For the SoScale2UniformDragger, only the X and Y components are used,
the Z component will always be equal to 1 (ie no scaling).
SoFieldSensor * SoScale2UniformDragger::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.
SbLineProjector * SoScale2UniformDragger::lineProj [protected] This API
member is considered internal to the library, as it is not likely to be
of interest to the application programmer.
