It works now for my case with:
self.tvcolumn[1].set_sizing(gtk.TREE_VIEW_COLUMN_FIXED)
self.tvcolumn[1].set_resizable(True)
self.tvcolumn[1].set_fixed_width(80)

self.tvcolumn[2].set_sizing(gtk.TREE_VIEW_COLUMN_FIXED)
self.tvcolumn[2].set_resizable(True)
self.tvcolumn[2].set_fixed_width(20)

self.tvcolumn[3].set_sizing(gtk.TREE_VIEW_COLUMN_FIXED)
self.tvcolumn[3].set_resizable(True)
self.tvcolumn[3].set_fixed_width(80)

self.tvcolumn[0].set_sizing(gtk.TREE_VIEW_COLUMN_FIXED)
self.tvcolumn[0].set_expand(True)
self.tvcolumn[0].set_fixed_width(self.treeview1.allocation.width/2)

Thanks again!
