Add Item to my listbox in GUI ?!

Welcome All '

I hope to be Alright :)

I have listbox in my GUI , and Add pushbutton, any time when user want to add item in listbox he click on it and brows to chose file he want.

My Question is how i can handle (deal) with this item that user add it. note that the kind of this item is file with the extension .m

Also , I want to put this new item (ie.file) in the same folder that contain my code.

In Add callback function i do like this:

[filename, pathname] = uigetfile( ... {'*.m', 'All matlab-Files (.m)'; ... '.*','All Files (.)'}, ... 'Select Matlab File');

%if file selection is cancelled, pathname should be zero %and nothing should happen

if pathname == 0

    return
end

%gets the current data file names inside the listbox

inputFileNames = get(handles.listbox2,'String');

%if they only select one file, then the data will not be a cell %if more than one file selected at once, %then the data is stored inside a cell

if iscell(filename) == 0

    %add the most recent data file selected to the cell containing
    %all the data file names

    inputFileNames{end+1} = filename;

%else, data will be in cell format

else

    %stores full file path into inputFileNames

    for n = 1:length(filename)

   %notice the use of {}, because we are dealing with a cell here!

        inputFileNames{end+1} = filename{n};
    end

end

%updates the gui to display all filenames in the listbox

set(handles.listbox2,'String',inputFileNames);

When filename is a cell array

inputFileNames = [inputFileNames; filename];
