class SoWWWInlineP

Used to enumerate bbox rendering strategies.

Enumerator:

NEVER

Never render bounding box.

UNTIL_LOADED

Render bounding box until children are loaded.

ALWAYS

Always render bounding box, event when children are loaded.

Constructor.

Destructor.

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoNode.

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
    else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
      SoGroup * group = (SoGroup *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoNode.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoNode.

If the SoWWWInline::name field specifies a relative URL, use this method to name the complete URL.

If a full URL has been set with the SoWWWInline::setFullURLName() method, return it. If not, returns the value of the SoWWWInline::name field.

Returns a subgraph with a deep copy of the children of this node.

Start requesting URL data. This might trigger a callback to the callback set in SoWWWInline::setFetchURLCallBack().

Returns TRUE if SoWWWInline::requestURLData() has been called without being canceled by SoWWWInline::cancelURLData().

Return TRUE if the current child data has been read from file an URL.

Can be used to signal that URL loading has been canceled. You should use this method if you intend to request URL data more than once.

Manually set up the subgraph for this node.

Returns the child data for this node. This can be data read from a file, from an URL, from the contents of SoWWWInline::alternateRep or that was manually set with SoWWWInline::setChildData().

Returns the child list with the child data for this node.

Reimplemented from SoNode.

Sets the URL fetch callback. This will be used in SoWWWInline::readInstance() or when the user calls SoWWWInline::requestURLData().

Sets the bounding box visibility strategy.

Returns the bounding box visibility.

Sets the bounding box color.

Returns the bounding box color.

Sets whether children should be read from a local file, in the same manner as SoFile children are read.

If this is set to TRUE, the URL must point to a file on the local file system, as can be accessed by the standard C library fopen() call.

Returns if children should be read from local files.

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

This method should probably have been private in OIV. It is obsoleted in Coin. Let us know if you need it.

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoNode.

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

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 SoNode.

Action method for SoSearchAction.

Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node.

See also: SoSearchAction

Reimplemented from SoNode.

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

Action method for SoAudioRenderAction.

Does common processing for SoAudioRenderAction action instances.

Reimplemented from SoNode.

Convenience method that extends the current bounding box to include the box specified by center and size.

This method is mainly intended for internal use during file import operations.

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoNode.

Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is FALSE.

This is the protected method that should be overridden by extension node / engine / dragger / whatever subclasses which needs to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

  SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:

  void
  MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
                                    SbBool copyconnections)
  {
    // let parent superclasses do their thing (copy fields, copy
    // instance name, etc etc)
    SoNode::copyContents(from, copyconnections);

// [..then copy internal data..] }

Reimplemented from SoNode.

Name of file/URL where children should be read.

Center of bounding box.

Size of bounding box.

Alternate representation. Used when children can't be read from name.
