NAME

       SoScale1Dragger -

       The SoScale1Dragger class provides a mechanism for the end-user to
       scale in one dimension.

       Here’s how the dragger looks with its default geometry in the inactive
       state:

Detailed Description

       The SoScale1Dragger class provides a mechanism for the end-user to
       scale in one dimension.

       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. (Use a transformation node in front of the dragger to
       position it and re-orient it to scale along any vector.)

Constructor & Destructor Documentation

   SoScale1Dragger::SoScale1Dragger (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 SoScale1Dragger
         -->"this"
               "callbackList"
               "topSeparator"
                  "motionMatrix"
                  "geomSeparator"
         -->         "scalerSwitch"
         -->            "scaler"
         -->            "scalerActive"
         -->         "feedbackSwitch"
         -->            "feedback"
         -->            "feedbackActive"
         .fi

       (See SoBaseKit::printDiagram() for information about the output formatting.)

       Detailed information on catalog parts:

       (See SoBaseKit::printTable() for information about the output formatting.)

   SoScale1Dragger::~SoScale1Dragger (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 SoScale1Dragger::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 SoScale1Dragger::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 SoScale1Dragger::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 SoScale1Dragger::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 SoScale1Dragger::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 SoScale1Dragger::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 SoScale1Dragger::scaleFactor Continuously updated to contain the
       current vector of scaling along the X, Y and Z axes.
       For the SoScale1Dragger, only the X component is used, the Y and Z
       components will always be equal to 1 (ie no scaling).

   SoFieldSensor * SoScale1Dragger::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 * SoScale1Dragger::lineProj [protected] This API member is
       considered internal to the library, as it is not likely to be of
       interest to the application programmer.
