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, i.e. the X, Y and Z components of the **SoScaleUniformDragger::scaleFactor** will always be exactly equal. **See also** **SoScale2UniformDragger** ## Constructor & Destructor Documentation ### SoScaleUniformDragger::SoScaleUniformDragger (void ) Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry. Nodekit 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 --- ``` (See **SoBaseKit::printTable()** 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 ### SoType SoScaleUniformDragger::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoScaleUniformDragger::getTypeId (void ) const \[virtual\] Returns the type identification of an object derived from a class inheriting **SoBase**. This is used for runtime type checking and "downward" casting. Reimplemented from **SoDragger**. ### const SoFieldData \*\* SoScaleUniformDragger::getFieldDataPtr (void ) \[static\], \[protected\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ Returns the **SoFieldData** class which holds information about fields in this node. ### const SoFieldData \* SoScaleUniformDragger::getFieldData (void ) const \[protected\], \[virtual\] Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. Reimplemented from **SoDragger**. ### const SoNodekitCatalog \* SoScaleUniformDragger::getClassNodekitCatalog (void ) \[static\] Returns the nodekit catalog which defines the layout of this class' kit. ### const SoNodekitCatalog \* SoScaleUniformDragger::getNodekitCatalog (void ) const \[virtual\] Returns the nodekit catalog which defines the layout of this class' kit. Reimplemented from **SoDragger**. ### const SoNodekitCatalog \*\* SoScaleUniformDragger::getClassNodekitCatalogPtr (void ) \[static\], \[protected\] Returns the pointer to the pointer of the nodekit catalog for this class. ### 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()**. ### SbBool SoScaleUniformDragger::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.)
