## Detailed Description

The SoScale2Dragger class provides a mechanism for the end-user to scale in two dimensions.

Here's how the dragger looks with it's 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"
(See SoBaseKit::printDiagram() for information about the output formatting.) Detailed information on catalog parts:

SoScale2Dragger::~SoScale2Dragger | ( |  | ) | `[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 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 = FALSE
| ) | `[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.
