enum SoWWWAnchor::Mapping |
Enum that says how a picked node's position should be mapped to the URL.
SoWWWAnchor::SoWWWAnchor | ( | void | ) |
Constructor.
References description, map, name, NONE, and POINT.
SoWWWAnchor::~SoWWWAnchor | ( | ) | [protected, virtual] |
Destructor.
void SoWWWAnchor::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 SoLocateHighlight.
References SoNode::VRML1.
void SoWWWAnchor::setFullURLName | ( | const SbString & | url | ) |
Sets the full URL to url. If this is set, this URL will be used in callbacks instead of the URL set in SoWWWAnchor::name.
const SbString & SoWWWAnchor::getFullURLName | ( | void | ) |
Returns the full URL if it's set by SoWWWAnchor::setFullURLName(). Otherwise the contents of SoWWWAnchor::name is returned.
References name.
Referenced by handleEvent(), and redrawHighlighted().
void SoWWWAnchor::handleEvent | ( | SoHandleEventAction * | action | ) | [virtual] |
Action method for SoHandleEventAction.
Inspects the event data from action, and processes it if it is something which this node should react to.
Nodes influencing relevant state variables for how event handling is done also overrides this method.
Reimplemented from SoLocateHighlight.
References SoMouseButtonEvent::BUTTON1, SoEvent::getClassTypeId(), SoHandleEventAction::getEvent(), getFullURLName(), SoPickedPoint::getObjectPoint(), SoHandleEventAction::getPickedPoint(), SoLocateHighlight::handleEvent(), SoMouseButtonEvent::isButtonPressEvent(), map, POINT, and SbString::sprintf().
void SoWWWAnchor::setFetchURLCallBack | ( | SoWWWAnchorCB * | f, |
void * | userData | ||
) | [static] |
Sets the callback function f that is called when a SoWWWAnchor node is clicked on. This callback can among other things be used to provide a browser with the URL of this node.
The callback will be called with the URL, userData and a pointer to this node as arguments.
void SoWWWAnchor::setHighlightURLCallBack | ( | SoWWWAnchorCB * | f, |
void * | userData | ||
) | [static] |
Sets the callback function f that is called when a SoWWWAnchor node is highlighted. This callback can among other things be used to provide the user with a visual clue on which URL the node points to, for example by showing the URL as a string.
The callback will be called with the URL, userData and a pointer to this node as arguments.
void SoWWWAnchor::redrawHighlighted | ( | SoAction * | act, |
SbBool | isNowHighlighting | ||
) | [protected, virtual] |
Calls the highlight callback set up with SoWWWAnchor::setHighlightURLCallBack().
Reimplemented from SoLocateHighlight.
References getFullURLName(), and SoLocateHighlight::redrawHighlighted().
The name of the URL which the anchor points to.

The description of the URL.
Referenced by SoWWWAnchor().
Enum describing how a node's position should be mapped to the URL.
