Public Member Functions
virtual	~IProgressEventHandler ()
virtual void	handleEvent (Event evt)=0
	Handles an event.
Public Member Functions inherited from IRCObject
virtual void	addRef () const =0
	Increases the reference count of the actual object pointed to. This would take place during an assignment or copying.
virtual bool	decRef () const =0
	Decreases the reference count of the actual object pointed to. When the reference count falls to Zero, it deletes the actual object pointed to.
virtual int32	getRefCount () const =0
	Retrieve the current reference count of the actual object pointed to.

Static Public Member Functions
static EDL_API IProgressEventHandlerPtr	create (ProgressEventHandlerCallbackFunc cbFunc, void *cbPriv)
	Create the IProgressEventHandler object with a callback function.
