Stop/Continue button in gui

here is my test code for toggle button in gui,

% --- Executes on button press in togglebutton1.
function togglebutton1_Callback(hObject, eventdata, handles)
% hObject    handle to togglebutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% Hint: get(hObject,'Value') returns toggle state of togglebutton1
i=0;
while get(hObject,'Value')
     disp(i);
     i=i+1;
     pause(2);
end

It displays 0,1,2,3...when I press toggle button it stops and when I press again the toggle button it starts displaying from first,Is there a way to continue from where it had left, I want this button to work as 'stop/continue',This is only my test code where as my original code contains many for loops,serial communication and other functions

Hi,

I suggest you use i as variable in this fashion:

- declare i in the OpeningFcn:

handles.i = 0

- in the callback:

disp(handles.i);
handles.i=handles.i+1;
% Update handles structure
guidata(hObject, handles);
