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.
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"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:
CLASS SoScaleUniformDragger PVT "this", SoScaleUniformDragger --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- PVT "motionMatrix", SoMatrixTransform --- PVT "geomSeparator", SoSeparator --- PVT "scalerSwitch", SoSwitch --- "scaler", SoSeparator --- "scalerActive", SoSeparator --- PVT "feedbackSwitch", SoSwitch --- "feedback", SoSeparator --- "feedbackActive", SoSeparator ---

SoScaleUniformDragger::~SoScaleUniformDragger | ( | ) | [protected] |
Protected destructor.
(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)
References lineProj, and fieldSensor.
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.
