Event pending problem

["DC A" <adc4444 hotmail com>]

In the code:


for(gflt=0; gflt <=1; )
  {
      gtk_progress_bar_update((GtkProgressBar*)pbar, gflt);

      while(gtk_events_pending())
         gtk_main_iteration();

      gflt += 0.1;
      sleep(1);

      if( gflt > 1) break;
  }


Why use while loop for event pendings? You can clearly see that there is 
only one event pending which is gtk_progress_bar_update. so why looking for 
others? Thanks.
