Member Function Documentation

void activate (    )

Handle a click by loading the url.

const BVolume * getBVolume (    )  const [virtual]

Get the bounding volume. Returns: the bounding volume associated with the node. Reimplemented from Group.

void processSet_description (  const FieldValue &    sfstring, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_description eventIn handler. Parameters: sfstring  an SFString value. timestamp  the current time. Exceptions: std::bad_cast  if sfstring is not an SFString. std::bad_alloc  if memory allocation fails.

void processSet_parameter (  const FieldValue &    mfstring, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_parameter eventIn handler. Parameters: mfstring  an MFString value. timestamp  the current time. Exceptions: std::bad_cast  if mfstring is not an MFString. std::bad_alloc  if memory allocation fails.

void processSet_url (  const FieldValue &    mfstring, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_url eventIn handler. Parameters: mfstring  an MFString value. timestamp  the current time. Exceptions: std::bad_cast  if mfstring is not an MFString. std::bad_alloc  if memory allocation fails.

void render (  Viewer &    viewer, VrmlRenderContext    context )  [virtual]

Render the node. Parameters: viewer  a Viewer. context  a rendering context. Reimplemented from Group.

Anchor * toAnchor (    )  const [virtual]

Cast to an Anchor. Returns: a pointer to this node. Reimplemented from Node.
