void AddItem(TGShutterItem *item)

     Add shutter item to shutter frame.

Bool_t ProcessMessage(Long_t /*msg*/, Long_t parm1, Long_t /*parm2*/)

     Handle shutter messages.

Bool_t HandleTimer(TTimer *)

     Shutter item animation.

void Layout()

     Layout shutter items.

void SetSelectedItem(TGShutterItem *item)

     Set item to be the currently open shutter item.

TGShutterItem* GetItem(const char *name)

     returns a shutter item by name (name is hot string of shutter item)

void SavePrimitive(ofstream &out, Option_t *option)

     Save a shutter widget as a C++ statement(s) on output stream out.
