DESCRIPTION
This node refers to children through a URL (Universal Resource Locator). The application
is responsible for actually fetching data from the URL for an SoWWWInline node to display.
FIELDS
SoSFString name
Specifies the URL which the application should fetch as child data to this node (e.g.
"http://bogus.com/homeWorld.wrl.gz").
SoSFVec3f bboxCenter
Defines the center of the bounding box surrounding the URL child data.
SoSFVec3f bboxSize
Defines the size of the bounding box surrounding the URL child data.
SoSFNode alternateRep
Specifies child data that can be used instead of fetching data from the URL. On read,
if this field is set and there is no fetch URL callback registered, the alternateRep
will be used as the child data. Otherwise, it is the applications responsibility to
set the child data (see setChildData()).
METHODS
SoWWWInline()
Creates an inline 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 inline 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.
SoGroup * copyChildren() const
Return a copy of the hidden children as a Group. The children are set by the
application through setChildData().
void requestURLData()
Request that URL data be fetched. This will invoke the application callback to actually
fetch the data and can be called before the inline does this for itself (see
setFetchURLCallBack()).
SbBool isURLDataRequested() const
SbBool isURLDataHere() const
Return whether URL data has been requested and whether that data is here (i.e. whether
setChildData() has been called.)
void cancelURLDataRequest()
Cancel the active URL data fetch request.
void setChildData(SoNode *urlData)
SoNode * getChildData() const
Set/get the child data the inline should display. The application should set child data
after it has fetched data for an inline node.
static void setFetchURLCallBack(SoWWWInlineFetchURLCB *f, void *userData)
Application callbacks invoked when the inline needs its URL data fetched. This happens
the first time the inline is rendered, or if it needs to compute a bounding box and the
bboxSize field is not set, or when requestURLData() is called.
static void setBoundingBoxVisibility(BboxVisibility b)
static BboxVisibility getBoundingBoxVisibility()
This allows the application to specify when bounding boxes are displayed. The bounding
box can be rendered along with the children (ALWAYS), only until the child data is
loaded (UNTIL_LOADED), or not at all (NEVER). Default is UNTIL_LOADED
static void setBoundingBoxColor(SbColor &c)
static const SbColor & getBoundingBoxColor()
This allows the application to specify the color of bounding boxes displayed.
ACTION BEHAVIOR
SoGLRenderAction
This renders the child data if it has been set by the application. It will render a
wireframe bounding box as specified by the bboxCenter and bboxSize fields, and the
setting passed to setBoundingBoxVisibility(). If no fetch URL callback is set and the
alternateRep is not NULL, the alternateRep will be rendered until child data has been
set.
