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 object's Tag and the %| callback type separated by '_', e.g. 'slider2_Callback',%| 'figure1_CloseRequestFcn', 'axis1_ButtondownFcn'.%|%| H is the callback object's 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 stored in%| the figure's application data using GUIDATA. A copy of the structure%| is passed to each callback.  You can store additional information in%| this structure at GUI startup, and you can change the structure%| during callbacks.  Call guidata(h, handles) after changing your%| copy to replace the stored original so that subsequent callbacks see%| the updates. Type "help guihandles" and "help guidata" for more%| information.%|%| VARARGIN contains any extra arguments you have passed to the%| callback. Specify the extra arguments by editing the callback%| property in the inspector. By default, GUIDE sets the property to:%| <MFILENAME>('<SUBFUNCTION_NAME>', gcbo, [], guidata(gcbo))%| Add any extra arguments after the last argument, before the final%| closing parenthesis.% --------------------------------------------------------------------function varargout = pushbutton4_Callback(h, eventdata, handles, varargin)[filename, pathname] = uigetfile( ...    {'*.wav', 'All wav-Files (*.wav)'; ...
