| 91 | %| ABOUT CALLBACKS: |
---|
| 92 | %| GUIDE automatically appends subfunction prototypes to this file, and |
---|
| 93 | %| sets objects' callback properties to call them through the FEVAL |
---|
| 94 | %| switchyard above. This comment describes that mechanism. |
---|
| 95 | %| |
---|
| 96 | %| Each callback subfunction declaration has the following form: |
---|
| 97 | %| <SUBFUNCTION_NAME>(H, EVENTDATA, HANDLES, VARARGIN) |
---|
| 98 | %| |
---|
| 99 | %| The subfunction name is composed using the object's Tag and the |
---|
| 100 | %| callback type separated by '_', e.g. 'slider2_Callback', |
---|
| 101 | %| 'figure1_CloseRequestFcn', 'axis1_ButtondownFcn'. |
---|
| 102 | %| |
---|
| 103 | %| H is the callback object's handle (obtained using GCBO). |
---|
| 104 | %| |
---|
| 105 | %| EVENTDATA is empty, but reserved for future use. |
---|
| 106 | %| |
---|
| 107 | %| HANDLES is a structure containing handles of components in GUI using |
---|
| 108 | %| tags as fieldnames, e.g. handles.figure1, handles.slider2. This |
---|
| 109 | %| structure is created at GUI startup using GUIHANDLES and stored in |
---|
| 110 | %| the figure's application data using GUIDATA. A copy of the structure |
---|
| 111 | %| is passed to each callback. You can store additional information in |
---|
| 112 | %| this structure at GUI startup, and you can change the structure |
---|
| 113 | %| during callbacks. Call guidata(h, handles) after changing your |
---|
| 114 | %| copy to replace the stored original so that subsequent callbacks see |
---|
| 115 | %| the updates. Type "help guihandles" and "help guidata" for more |
---|
| 116 | %| information. |
---|
| 117 | %| |
---|
| 118 | %| VARARGIN contains any extra arguments you have passed to the |
---|
| 119 | %| callback. Specify the extra arguments by editing the callback |
---|
| 120 | %| property in the inspector. By default, GUIDE sets the property to: |
---|
| 121 | %| <MFILENAME>('<SUBFUNCTION_NAME>', gcbo, [], guidata(gcbo)) |
---|
| 122 | %| Add any extra arguments after the last argument, before the final |
---|
| 123 | %| closing parenthesis. |

| 132 | % Obtaining the Figure Handle from Within a Callback. In general, dismissing a modal figure requires the handle |
