Subject: Gtk::ProgressBar set_fraction doesn't work

Hello,

i have some problems with the Gtk::ProgressBar. I download a file and i 
want to show a progressbar. The method below creates a new dialog with a 
bar and starts the download for each file. The puts-line work very well 
and i can see a dialog, there is no update. Does anybody know whats 
going wrong?

Thanks to all the people in this great community,
  Patrick


def download_podcasts(liststore_podcasts)
         dialog = Gtk::Dialog.new("Download",
                                  $main_application_window,
                                  Gtk::Dialog::DESTROY_WITH_PARENT)

         bar = Gtk::ProgressBar.new
         bar.fraction = 0.0

         dialog.vbox.add(bar)
         dialog.show_all

         liststore_podcasts.each do |model,path,row|
                 row[3].download do |received, total|
                         bar.fraction = received.to_f / total.to_f
                         bar.text = (bar.fraction * 100).to_s + "%"
                         puts received.to_s + " / " + total.to_s + " = " 
+ bar.fraction.to_s
                 end
         end

         dialog.destroy
end
