ProgressBar

Hi

I would appreciate some help on the following problem I am experiencing.

I am migrating a suite from Tkinter to PyGtk and cannot update a
Progressbar within a loop e.g.

import pygtk
pygtk.require('2.0')
import gtk

class ProgressBar:
    def __init__(self, scrn, max):
        align = gtk.Alignment(0.5, 0.5, 1, 0)
        align.show()
        scrn.add(align)
        self.progBar = gtk.ProgressBar()
        self.progBar.set_size_request(100, 20)
        self.progBar.set_orientation(0)  # left to right
        self.progBar.set_fraction(0)
        self.progBar.show()
        align.add(self.progBar)
        self.max = max

    def increment(self, done):
        frac = float((done * 100.0) / self.max)
        self.progBar.set_text("%s (%s%s)" % \
           ("Updating Files", str(frac), "%"))
        self.progBar.set_fraction(frac/100.0)

if  __name__ == "__main__":
    def start(wd):
        pb = ProgressBar(box, 1000)
        for x in range(1000):
            ok = pb.increment(x)
    win = gtk.Window()
    win.show()
    box = gtk.VBox(gtk.FALSE, 0)
    box.show()
    win.add(box)
    but = gtk.Button("start")
    but.connect("clicked", start)
    box.add(but)
    but.show()
    gtk.main()

Any help would be appreciated.

Thanks

Paul
