opps, i forgot ...
I will launch a thread for controlling the progress ... Umm, its a good idea to use the ''popen'' (i didn't thought how can i make the progress bar 'progress' ... so it can be a good thing to take the output, or so, and sums up the current value of the progress bar).

Thanks again ^_^>
