[Naoko Shimakawa <simakawa ssd sony co jp>]

Hi!

Thank you Mr.Scherf !!
I can update my progress bar!!!
Thank you very much!

My mistake is here.
>  while (gtk_events_pending ())
> 	gtk_main_iteration ();

The FAQ wrote: 
   while( gtk_main_iteration() );
But it doesn't go.
I don't know why.

Thank you so much !(^-^)

Here changed.

    //update progress bar
    for( gflt=0; gflt<=1;  ){
        gtk_progress_bar_update( (GtkProgressBar*)pbar, gflt );
        //update
        while (gtk_events_pending ())
            gtk_main_iteration ();
        gflt += 0.1;
        sleep(1);
       if ( gflt > 1 ) break;
    }
