## Detailed Description

The SoRotateSphericalDragger class is for rotating geometry in any direction.

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

Use an instance of this dragger class in your scenegraph to let the end-users of your application rotate geometry freely in any direction.

For the initial dragger orientation and the dragger geometry positioning itself, use some kind of transformation node in your scenegraph, as usual.

## Constructor & Destructor Documentation

SoRotateSphericalDragger::SoRotateSphericalDragger | ( | 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 SoRotateSphericalDragger
    -->"this"
          "callbackList"
          "topSeparator"
             "motionMatrix"
             "geomSeparator"
    -->         "rotatorSwitch"
    -->            "rotator"
    -->            "rotatorActive"
    -->         "feedbackSwitch"
    -->            "feedback"
    -->            "feedbackActive"

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

Detailed information on catalog parts:

    CLASS SoRotateSphericalDragger
    PVT   "this",  SoRotateSphericalDragger  ---
          "callbackList",  SoNodeKitListPart [ SoCallback, SoEventCallback ]
    PVT   "topSeparator",  SoSeparator  ---
    PVT   "motionMatrix",  SoMatrixTransform  ---
    PVT   "geomSeparator",  SoSeparator  ---
    PVT   "rotatorSwitch",  SoSwitch  ---
          "rotator",  SoSeparator  ---
          "rotatorActive",  SoSeparator  ---
    PVT   "feedbackSwitch",  SoSwitch  ---
          "feedback",  SoSeparator  ---
          "feedbackActive",  SoSeparator  ---

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

SoRotateSphericalDragger::~SoRotateSphericalDragger | ( | void |  | ) |
| protectedvirtual

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 SoRotateSphericalDragger::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
}
}

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.

Reimplemented from SoDragger.

const SoFieldData * SoRotateSphericalDragger::getFieldData | ( | void |  | ) | const
| protectedvirtual

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 * SoRotateSphericalDragger::getNodekitCatalog | ( | void |  | ) | const
| virtual

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

void SoRotateSphericalDragger::setProjector | ( | SbSphereProjector * | p | ) |

Replace the default sphere projection strategy. You may want to do this if you change the dragger geometry, for instance.

The default projection is an SbSpherePlaneProjector.

See also
  SbSphereSectionProjector, SbSphereSheetProjector

const SbSphereProjector * SoRotateSphericalDragger::getProjector | ( | void |  | ) | const

Returns projector instance used for converting from user interaction dragger movements to 3D dragger re-orientation.

See also
  setProjector()

SbBool SoRotateSphericalDragger::setUpConnections | ( | SbBool | onoff,
|  | SbBool | doitalways = `FALSE`
| ) |  |
| protectedvirtual

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 SoRotateSphericalDragger::copyContents | ( | const SoFieldContainer * | from,
|  | SbBool | copyconnections
| ) |  |
| protectedvirtual

Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is `FALSE`.

This is the protected method that should be overridden by extension node / engine / dragger / whatever subclasses which needs to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:

void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
SbBool copyconnections)
{
// let parent superclasses do their thing (copy fields, copy
// instance name, etc etc)
SoNode::copyContents(from, copyconnections);
// [..then copy internal data..]
}

## Member Data Documentation

SoSFRotation SoRotateSphericalDragger::rotation

This field is continuously updated to contain the rotation of the current direction vector of the dragger.

The application programmer using this dragger in his scenegraph should connect the relevant node fields in the scene to this field to make them follow the dragger orientation.
