How to put uigetfile data from Pushbutton into Listbox?

Hello Everyone,

Iam still new to GUI Logic of Matlab. I just want to get a logic code to set filename or uigetfile data into Listbox like this :

So, when the pushbutton contained with uigetfile code :

function loadekstrak_Callback(hObject, eventdata, handles)
        % hObject    handle to loadekstrak (see GCBO)
        % eventdata  reserved - to be defined in a future version of MATLAB
        % handles    structure with handles and user data (see GUIDATA)
          push = guidata(gcbo); 
[namafile,arah]=uigetfile({'*.txt', 'Text-Files (*.txt)'},'Load Data Magnet Format IAGA WDS (Definitif / Variatif)', 'Multiselect','on');
         cd(arah);
         full = fullfile(arah, namafile);
         namafiles = cellstr(sort(namafile)); %Mensortir Kombinasi Data Yang Dipilih secara acak (PENTING)
         fulls = string(full);
         nfiles1 = size(full,2);
         nfiles2 = numel(full);
         f = cellstr(fullfile(arah,namafile));
         file = length(f);

The callback function of listbox will add those information. And by using the code below, i am still get an error as the output :

function listbox1_Callback(hObject, eventdata, handles)
% hObject    handle to listbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns listbox1 contents as cell array
%        contents{get(hObject,'Value')} returns selected item from listbox1
list = guidata(gcbo);
index_selected = get(handle.push,'Value');
list = get(hObject,'String');
item_selected = list{index_selected}; % Convert from cell array
                                      % to string

Iam just trying to get information of " namafile " (filename from uigetfile) or "full" variable to be set into the listbox once the pushbutton was clicked and the data was selected respectively....

So anyone, would you mind to help me to find a logic for the code? I just dont understand if iam just read from the documentation.....

Thank you very much everyone /.\ /.\ /.\

This part of the code does not do anything useful:

 cd(arah);
 full = fullfile(arah, namafile);
 namafiles = cellstr(sort(namafile)); %Mensortir Kombinasi Data Yang Dipilih secara acak (PENTING)
 fulls = string(full);
 nfiles1 = size(full,2);
 nfiles2 = numel(full);
 f = cellstr(fullfile(arah,namafile));
 file = length(f);

I'm not sure what you want to achieve. With some guessing:

function loadekstrak_Callback(hObject, eventdata, handles)
% hObject    handle to loadekstrak (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
push = guidata(gcbo); 
[namafile,arah] = uigetfile({'*.txt', 'Text-Files (*.txt)'}, ...
    'Load Data Magnet Format IAGA WDS (Definitif / Variatif)', ...
    'Multiselect', 'on');
if isempty(namafile)  % canceled
   return;
end
push.listbox1.String = fullfile(ara, cellstr(namafile));
end

Omg, you did it, that was Great. I just want to get the logic of GUI' code, and i know it by now....

Thank you so much, Sir Jans..

Actually, I want to show some loading file (from selected files) which want to be proceeded at my program in that listbox....
