DESCRIPTION

This node defines a separator group which has a URL (Universal Resource Locator) hyperlink. When clicked on, this node invokes an application callback to fetch the URL. The application may fetch the data itself, or call a World Wide Web browser like the HTML based Netscape Navigator or the VRML based WebSpace Navigator to load the URL.

FIELDS

SoSFString name

URL which the application will be called back to fetch when this node is activated by a left mouse click (e.g. "http://www.sgi.com/Technology/Inventor").

SoSFString description

A description of the URL which may make more sense to users than the URL itself (e.g. "The Open Inventor Home Page").

SoSFEnum map

Specifies what additional information should be added to the end of the URL when passed back to the application for fetching. If set to POINT, then the x,y,z location of the object space intersection point when the mouse was clicked will be suffixed to the URL. Since the comma character does not transmit through some web browsers, it is written in hex form (e.g. if the intersection point is 17,4.5,1 the URL passed to the application callback would be "http://www.sgi.com/Technology/Inventor?17%2c4.5%2c1").

METHODS

SoWWWAnchor()

Creates an anchor node with default settings.

static SoType getClassTypeId()

Returns type identifier for this class.

void setFullURLName(const SbString &url)

const SbString & getFullURLName()

If the name field contains a relative URL (e.g. "foo.wrl" instead of "http://bogus.com/foo.wrl"), the anchor cannot resolve the URL reference. This method allows the application to tell the anchor what it's full URL should be. getFullURLName() returns the fullURL set here, or if not set, returns the contents of the name field.

static void setFetchURLCallBack(SoWWWAnchorCB *f, void *userData)

Application callbacks invoked when the mouse is clicked on an anchor so that the application can fetch the URL or call Netscape or WebSpace to fetch the URL.

static void setHighlightURLCallBack(SoWWWAnchorCB *f, void *userData)

Application callbacks invoked when the mouse is moved over an anchor so that the app can provide feedback such as changing the cursor, or displaying the anchor description and name.

ACTION BEHAVIOR

SoHandleEventAction

When the left mouse is clicked over a child of this anchor node, the application is called back to fetch the URL (see setFetchURLCallBack()).
