man SoCenterballManip (Fonctions bibliothèques) -

NAME

SoCenterballManip -

SYNOPSIS



#include <Inventor/manips/SoCenterballManip.h>

Inherits SoTransformManip.

Detailed Description

The SoCenterballManip wraps an SoCenterballDragger for convenience.

The manipulator class takes care of wrapping up the SoCenterballDragger in a simple and convenient API for the application programmer, making it automatically surround the geometry it influences and taking care of the book-keeping routines for it's interaction with the relevant fields of an SoTransformation node.

Constructor & Destructor Documentation

SoCenterballManip::SoCenterballManip (void)

Default constructor. Allocates an SoCenterballDragger and an SoSurroundScale node to surround the geometry within our part of the scenegraph.

SoCenterballManip::~SoCenterballManip () [protected]

Destructor.

Member Function Documentation

SoType SoCenterballManip::getClassTypeId (void) [static]

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

Reimplemented from SoTransformManip.

SoType SoCenterballManip::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.

Reimplemented from SoTransformManip.

const SoFieldData ** SoCenterballManip::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 SoTransformManip.

const SoFieldData * SoCenterballManip::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 SoTransformManip.

void SoCenterballManip::initClass (void) [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoTransformManip.

void SoCenterballManip::setDragger (SoDragger * newDragger) [protected, virtual]

Sets up the dragger instance to be controlled by this manipulator.

Reimplemented from SoTransformManip.

void SoCenterballManip::fieldSensorCB (void * f, SoSensor * s) [static, protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Callback to update motion matrix when a field is modified.

Reimplemented from SoTransformManip.

void SoCenterballManip::valueChangedCB (void * f, SoDragger * d) [static, protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Callback to update field values when motion matrix changes.

Reimplemented from SoTransformManip.
