NAME

SoTransformerDragger -

SYNOPSIS



#include <Inventor/draggers/SoTransformerDragger.h>

Inherits SoDragger.

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 scenegraph possible with very little effort.

SoTransformerDragger::~SoTransformerDragger () [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

SoType SoTransformerDragger::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoDragger.

SoType SoTransformerDragger::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example: 

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
    else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
      SoGroup * group = (SoGroup *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

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.

Reimplemented from SoDragger.

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.

Reimplemented from SoDragger.

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.

Reimplemented from SoDragger.

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().

Reimplemented from SoDragger.

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 = 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 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 scenegraph 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's 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.

Reimplemented from SoDragger.
