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 = close_button_Callback(h, eventdata, handles, varargin)% Stub for Callback of the uicontrol handles.close_button.%Stub for Callback of the uicontrol handles.close_button.% % Obtaining the Figure Handle from Within a Callback.   In general, dismissing a modal figure requires the handle% of the figure. Since most GUIs hide figure handles to prevent accidental access, the gcbf (get callback figure)% command provides the most effective method to get the figure handle from within a callback routine.% % gcbf returns the handle of the figure containing the object whose callback is executing. This enables you to use% gcbf in the callback of the component that will dismiss the dialog. For example, suppose your dialog includes a% push button (tagged pushbutton1) that closes the dialog. Its callback could include a call to delete at the end of% its callback subfunction.disp('closing');% match_param_out.max_disparity = handles.max_disparity;% match_param_out.corner_sigma = handles.corner_sigma;% match_param_out.match_half_size = handles.match_half_size;uiresume(handles.figure1);% --------------------------------------------------------------------function varargout = pushbutton2_Callback(h, eventdata, handles, varargin)% Stub for Callback of the uicontrol handles.pushbutton2.disp('pushbutton2 Callback not implemented yet.')% --------------------------------------------------------------------function varargout = width_button_Callback(h, eventdata, handles, varargin)nc = str2num(get(handles.width_button, 'String'));minnc = 0;maxnc = 20;if (isempty(nc) | (nc <= minnc)  | (nc >maxnc))    nc = handles.match_half_size;    WARNDLG(['out of range' num2str(minnc) '-' num2str(maxnc)],'ooops') end;handles.match_half_size = nc;set(handles.width_button, 'String', num2str(handles.match_half_size));%save dataguidata(handles.figure1, handles);% --------------------------------------------------------------------function varargout = max_disparity_button_Callback(h, eventdata, handles, varargin)% Stub for Callback of the uicontrol handles.max_disparity_button.nc = str2num(get(handles.max_disparity_button, 'String'));minnc = 1;maxnc = 1000;if (isempty(nc) | (nc < minnc)  | (nc >maxnc))    nc = handles.max_disparity;    WARNDLG(['out of range' num2str(minnc) '-' num2str(maxnc)],'ooops') end;if (nc >100)    WARNDLG('Big Max disparities take a lot of computation','hint') endhandles.max_disparity = nc;set(handles.max_disparity_button, 'String', num2str(handles.max_disparity));%save dataguidata(handles.figure1, handles);
