GUI new callback name

Hi,

I created Gui with a long (decriptive) name that I would like to keep but at the same time it would be good to have an option to use a shorter name just for call the gui in matlab command window. At which part of gui should I change the name so that the old remains and the new is just used for callback? I try to change it in a few place (and even in the whole gui) but each time got error message:

Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)ConvertMatLab_gui('OpenSave_Callback',hObject,eventdata,guidata(hObject))

Ps. The message refers to the old name 'ConvertMatLab_gui'

I can tell that you are using a GUI created with GUIDE.

Edit ConvertMatLab_gui.m

Near line 31 you will find lines

% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @BrainMRI_GUI_OpeningFcn, ...
                   'gui_OutputFcn',  @BrainMRI_GUI_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);

That mfilename is pulling in the name of the .m file that is running, and storing it in the struct. Later when the helper routine gui_mainfcn() is called, that gui_Name field will be used to decide which .fig to call. But that is a problem, because the .fig still has the old name, not the new name.

You have two choices:

1. You can edit that mfilename to be 'ConvertMatLab_gui' to hard-code the name; or
2. Instead of changing anything in this file, have your short name be a small script that just invokes the one with the longer name. For example if the short name is CM then CM.m could contain

function varargout = cm(varargin)
    if nargout == 0
        ConvertMatLab_gui(varargin{:});
    else
        [varargout{1:nargout}] = ConvertMatLab_gui(varargin{:});
    end
end

Thank you,

The second option works. I couldn't grasp how to proceed with option one, what exactly to edit in the hard-code :-)

gui_State = struct('gui_Name',       'ConvertMatLab_gui', ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @BrainMRI_GUI_OpeningFcn, ...
                   'gui_OutputFcn',  @BrainMRI_GUI_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);

but I think the wrapper function is a better option.
