This comment describes that mechanism. %| %| Each callback subfunction declaration has the following form: %| SUBFUNCTION_NAME(H, EVENTDATA, HANDLES, VARARGIN) %| %| The subfunction name is composed using the objects Tag and the %| callback type separated by _, e.g. slider2_Callback, %| figure1_CloseRequestFcn, axis1_ButtondownFcn. %| %| H is the callback objects handle (obtained using GCBO). %| %| EVENTDATA is empty, but reserved for future use. %| %| HANDLES is a structure containing handles of components in GUI using %| tags as fieldnames, e.g. handles.figure1, handles.slider2. This %| structure is created at GUI startup using GUIHANDLES and s
