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 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. |
|
This function performs the typical operation of a node for any action. 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 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. |
|
Returns |
|
Notifies all auditors for this instance when changes are made. Reimplemented from SoNode. |
|
Set of packed 32-bit RGBA vectors. The most significant 24 bits specifies 8 bits each for the red, green and blue components. The least significant 8 bits specifies the transparency value, where 0x00 means completely transparent, and 0xff completely opaque. |
