Writing in a listbox

I am trying to write a list in a listbox.
code:
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
error = getappdata(0, 'error_norm');
rows = size(error,1);
for i = 1:rows
set(handles.listbox1,'string',strcat('filt_',num2str(i)));
for j = 1:length(error)
set(handles.listbox1,'string',strcat('sig_',num2str(i),'_',num2str(j)));
for k = 1:length(error{j}.main)
set(handles.listbox1,'string',strcat('seg_',num2str(i),'_',num2str(j),'_',num2str(k)));
end
end
end
where 'error' is a array of structure . i want to write on list box something like this:
filt_1
sig_1_1
seg_1_1_1
seg_1_1_2
sig_1_2
seg_1_2_1
seg_1_2_2
but apparently, 'set' function overwrites, so all i am getting is only 1 element and the last element.
How do i make it write all of it, any help will be appreciated.

You need to create a cell array of strings first, and then set() that cell array as the String property of the handle.

all_choices = get(hObject, 'String');
choice_idx = get(hObject, 'Value');
chosen_string = all_choices{choice_idx};
