Member Function Documentation

virtual void osgGA::CameraManipulator::accept (  GUIEventHandlerVisitor &    v )  [inline, virtual]

Handle visitations. Implements osgGA::GUIEventHandler.

virtual osg::Camera* osgGA::CameraManipulator::getCamera (    )  [virtual]

Get the attached camera. Reimplemented in osgGA::KeySwitchCameraManipulator.

virtual const osg::Camera* osgGA::CameraManipulator::getCamera (    )  const [virtual]

Get the attached camera. Reimplemented in osgGA::KeySwitchCameraManipulator.

virtual osg::Node* osgGA::CameraManipulator::getNode (    )  [inline, virtual]

Return node if attached. Reimplemented in osgGA::DriveManipulator, osgGA::FlightManipulator, osgGA::KeySwitchCameraManipulator, and osgGA::TrackballManipulator.

virtual const osg::Node* osgGA::CameraManipulator::getNode (    )  const [inline, virtual]

Return const node if attached. Reimplemented in osgGA::DriveManipulator, osgGA::FlightManipulator, osgGA::KeySwitchCameraManipulator, and osgGA::TrackballManipulator.

virtual bool osgGA::CameraManipulator::handle (  const GUIEventAdapter &    ea, GUIActionAdapter &    us )  [virtual]

Handle events, return true if handled, false otherwise. Implements osgGA::GUIEventHandler. Reimplemented in osgGA::DriveManipulator, osgGA::FlightManipulator, osgGA::KeySwitchCameraManipulator, and osgGA::TrackballManipulator.

virtual void osgGA::CameraManipulator::home (  const GUIEventAdapter &   , GUIActionAdapter &    )  [inline, virtual]

Move the camera to the default position. May be ignored by manipulators if home functionality is not appropriate. Reimplemented in osgGA::DriveManipulator, osgGA::FlightManipulator, osgGA::KeySwitchCameraManipulator, and osgGA::TrackballManipulator.

virtual void osgGA::CameraManipulator::init (  const GUIEventAdapter &   , GUIActionAdapter &    )  [inline, virtual]

Start/restart the manipulator. FIXME: what does this actually mean? Provide examples. Reimplemented in osgGA::DriveManipulator, osgGA::FlightManipulator, osgGA::KeySwitchCameraManipulator, and osgGA::TrackballManipulator.

virtual void osgGA::CameraManipulator::setCamera (  osg::Camera *    )  [virtual]

Attach a camera to the manipulator to be used for specifying view. Reimplemented in osgGA::KeySwitchCameraManipulator.

virtual void osgGA::CameraManipulator::setNode (  osg::Node *    )  [inline, virtual]

Attach a node to the manipulator, automatically detaching any previously attached node. setNode(NULL) detaches previous nodes. May be ignored by manipulators which do not require a reference model. Reimplemented in osgGA::DriveManipulator, osgGA::FlightManipulator, osgGA::KeySwitchCameraManipulator, and osgGA::TrackballManipulator.
