Progressbar

["Sandra Derbring" <sandra derbring gmail com>]

Hello,

I have a problem with a progressbar. I want, for every file I look into, for the bar to show some progress, so that while you wait for the program to finish, the whole time can see the bar moving. When I implement it, all that happens is that the bar gets filled first after the program's finished. How do I make it show during the process? 

self.progressbar = gtk.ProgressBar()
self.progressbar.show()

self.step = 1/len(list)

for file in list:
      self.x += self.step
      #do smth with file
      self.progressbar.set_fraction(self.x)
