slider_forall_Callback(hObject, eventdata, handles)

function slider_forall_Callback(hObject, eventdata, handles)

% Create a GUI with XX listboxes and a slider..... and paste the following
% code in the callback of silder
% hObject    handle to slider_forall (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'Value') returns position of slider
%        get(hObject,'Min') and get(hObject,'Max') to determine range of slider
 
% Set all the listboxes to the slider position
