NAME SoWWWInline "" "" { node that refers to children through a URL }
INCLUDE nodes/SoWWWInline.h
DESC {
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.
}
TYPEDEF void SoWWWInlineFetchURLCB "(const SbString &url, void *userData, SoWWWInline *node)"
ENUM BboxVisibility {
NEVER "Do not show bounding box",
UNTIL_LOADED "Show bounding box (if specified) until data is loaded",
ALWAYS "Show bounding box along with data"
}
FIELD name {
Specifies the URL which the application should fetch as child data to this node
(e.g. "http://bogus.com/homeWorld.wrl.gz").
}
FIELD bboxCenter {
Defines the center of the bounding box surrounding the URL child data.
}
FIELD bboxSize {
Defines the size of the bounding box surrounding the URL child data.
}
FIELD 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 \ksetChildData()\.).
}
METHOD "" SoWWWInline() {
Creates an inline node with default settings.
}
METHOD "" static SoType getClassTypeId() {
Returns type identifier for this class.
}
METHOD "" void setFullURLName(const SbString &url) {}
METHOD "" 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.
\kgetFullURLName()\. returns the fullURL set here, or if not set, returns
the contents of the name field.
}
METHOD "" SoGroup * copyChildren() const {
Return a copy of the hidden children as a Group. The children
are set by the application through \ksetChildData()\..
}
METHOD reqURLData 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 \ksetFetchURLCallBack()\.).
}
METHOD isURLDataReq SbBool isURLDataRequested() const {}
METHOD "" SbBool isURLDataHere() const {
Return whether URL data has been requested and whether that data
is here (i.e. whether \ksetChildData()\. has been called.)
}
METHOD cancelURLDataReq void cancelURLDataRequest() {
Cancel the active URL data fetch request.
}
METHOD "" void setChildData(SoNode *urlData) {}
METHOD "" 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.
}
METHOD setFetchCB 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 \krequestURLData()\. is called.
}
METHOD setBboxVis static void setBoundingBoxVisibility(BboxVisibility b) {}
METHOD getBboxVis static BboxVisibility getBoundingBoxVisibility() {
This allows the application to specify when bounding boxes are displayed.
The bounding box can be rendered along with the
children (\kALWAYS\.), only until the child data is loaded (\kUNTIL_LOADED\.),
or not at all (\kNEVER\.). Default is \kUNTIL_LOADED\.
}
METHOD setBboxCol static void setBoundingBoxColor(SbColor &c) {}
METHOD getBboxCol static const SbColor &getBoundingBoxColor() {
This allows the application to specify the color of bounding boxes displayed.
}
ACTION 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 \kbboxCenter\.
and \kbboxSize\. fields, and the setting passed to \ksetBoundingBoxVisibility()\..
If no fetch URL callback is set and the \kalternateRep\.
is not NULL, the \kalternateRep\. will be rendered until child data has been set.
