  Try to set the pagesize of the adjustment to 0. It seems the slider
  tries to fit a 'page' in the range [min...max], like it is needed for
  scrollbars, but not so useful for scales without a 'page'. So
  gtk_adjustment_new (0, 0, 1000, 1, 1, 0) should make the slider value
  get the whole range.
