**nextActionMethodIndex** = 0\ ## Detailed Description The **SoTransformerDragger** provides geometry for translation, scaling and rotations. Here's how the dragger looks with its default geometry in the inactive state: Translate the dragger by clicking and dragging any of the (invisible) sides. Translation will default be done in the plane of the side the end-user selected. The user can hold down a SHIFT key to lock translation to a single of the axes in the plane. By holding down a CTRL key instead, translation can be done along the plane's normal vector. Scaling is done by dragging the corner cubes. By default, uniform scaling will be done. Hold down SHIFT before selecting any of the corners to do non-uniform scaling. Uniform scaling towards a corner-point can be accomplished by holding down CTRL before clicking and dragging one of the cubes. Rotation is done by dragging any of the 6 end-markers of the axis cross. The initial drag direction decides which orientation the rotation will be done in. Hold down SHIFT to do free-form rotation around the sphere instead. This is a big and complex dragger which needs a fair amount of proper documentation when provided in end-user applications. If what you are trying to accomplish in your application does not really demand most of the features of this dragger, you are advised to investigate whether or not any of the less complex draggers can fulfill your requirements -- so you can provide an as simple as possible user interface to your end-users. For the application programmer's convenience, the Coin library also provides a manipulator class called **SoTransformerManip**, which wraps the **SoTransformerDragger** into the necessary mechanisms for making direct insertion of this dragger into a scene graph possible with very little effort. **See also** **SoTransformerManip** ## Member Enumeration Documentation ### enum SoTransformerDragger::State The various possible states the dragger might be in at any given time. That is: either SoTransformerDragger::INACTIVE if there's no interaction, or any of the other values to indicate what operation the end-user is currently executing. ## Constructor & Destructor Documentation ### SoTransformerDragger::SoTransformerDragger (void ) Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.

(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 SoTransformerDragger::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoTransformerDragger::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 \*\* SoTransformerDragger::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 \* SoTransformerDragger::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 \* SoTransformerDragger::getClassNodekitCatalog (void ) \[static\] Returns the nodekit catalog which defines the layout of this class' kit. ### const SoNodekitCatalog \* SoTransformerDragger::getNodekitCatalog (void ) const \[virtual\] Returns the nodekit catalog which defines the layout of this class' kit. Reimplemented from **SoDragger**. ### const SoNodekitCatalog \*\* SoTransformerDragger::getClassNodekitCatalogPtr (void ) \[static\], \[protected\] Returns the pointer to the pointer of the nodekit catalog for this class. ### void SoTransformerDragger::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()**. ### SoTransformerDragger::State SoTransformerDragger::getCurrentState (void ) Returns an indicator for the current operation executed on the dragger by the end-user -- or SoTransformerDragger::INACTIVE if none. ### SbBool SoTransformerDragger::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 SoTransformerDragger::setDefaultOnNonWritingFields (void ) \[protected\], \[virtual\] (Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed *are* writing extensions, see the information in the **SoBaseKit** class documentation.) This is a virtual method, and the code in it should call **SoField::setDefault()** with argument TRUE on part fields that should not be written upon scene graph export operations. This is typically done when: - 1\. field value is NULL and part is NULL by default - 2\. it is a leaf **SoGroup** or **SoSeparator** node with no children - 3\. it is a leaf listpart with no children and an **SoGroup** or **SoSeparator** container - 4\. it is a non-leaf part and it is of **SoGroup** type and all fields are at their default values Subclasses should usually override this to do additional settings for new member fields. From the subclass, do remember to call "upwards" to your superclass' **setDefaultOnNonWritingFields()** method.
