NAME
       SoCallbackList - The SoCallbackList is a container for callback
       function pointers.


SYNOPSIS
       #include <Inventor/lists/SoCallbackList.h>

   Public Member Functions
       SoCallbackList (void)
       ~SoCallbackList ()
       void addCallback (SoCallbackListCB *f, void *userData=NULL)
       void removeCallback (SoCallbackListCB *f, void *userdata=NULL)
       void clearCallbacks (void)
       int getNumCallbacks (void) const
       void invokeCallbacks (void *callbackdata)

Detailed Description
       The SoCallbackList is a container for callback function pointers.

       This list stores callback function pointers (along with user-specified
       extra data to pass to the callbacks) and provides a method for
       triggering the callback functions.

Constructor & Destructor Documentation
   SoCallbackList::SoCallbackList (void )
       Default constructor.

   SoCallbackList::~SoCallbackList (void )
       Destructor.

Member Function Documentation
   void SoCallbackList::addCallback (SoCallbackListCB * f, void * userdata =
       NULL)
       Append the callback function f to the list. It will be passed the
       userdata upon invocation.

   void SoCallbackList::removeCallback (SoCallbackListCB * f, void * userdata
       = NULL)
       Remove callback f from the list.

   void SoCallbackList::clearCallbacks (void )
       Remove all callbacks in the list.

   int SoCallbackList::getNumCallbacks (void ) const
       Returns number of callback functions.

   void SoCallbackList::invokeCallbacks (void * callbackdata)
       Invoke all callback functions, passing the userdata and the
       callbackdata as the first and second argument, respectively.


       All callbacks registered when the method is invoked will be triggered,
       even though if the code in one callback removes another callback.


       It is safe for a callback to remove itself or any other callbacks
       during execution.
