Is it possible to add a new variable to a popup menu while the GUI is running?

Hello,

I am writing a code that goes as follows:

% --- Executes during object creation, after setting all properties.
function popupmenu1_CreateFcn(hObject, eventdata, handles)
% hObject    handle to popupmenu1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: popupmenu controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

     Addition=inputdlg('Please Add New Client Name');

With this code, when the user clicks the push button an input dialog box will pop up for them to add a new client name. I then want to take this client name and add it as a new variable in the previously created pop-up menu. Is this possible?

current_entries = cellstr(get(handles.popupmenu1, 'String'));
current_entries{end+1} = Addition;
set(handles.popupmenu1, 'String', current_entries);

I get an error when I do this. Error using set Cell array of strings may only contain string and numeric matrices

I am not sure why that is since "Addition" holds a string value.

I figured it out. Thank you very much!!!

Can you tell me how did you fix it?

there is a missing quote at third line

Good point, Libros Construccion; I have edited the quote into place.

I'm not sure what you mean by 'add it as a new variable in the previously created pop-up menu'. If you want to set the default string that is shown in the dialog box use answer=inputdlg(prompt,dlg_title,num_lines,defAns) and set defAns to your last answer.

I want to take the user input and add that as a new variable to the pop-up menu I created.
