// class TAppButton.  Derived from TButtonGadget.  The only difference
// between this class and its derived class is in the handling of the
// button id.  Every button has an id of CM_DUMMY, which is a place holder
// for the frame's response table.  This class defines a new data member
// called 'RealId' which is different for each button.  The 'ReadId' is
// used by the frame window to determine which button has been pressed.
