PyGTK TreeColumns tous les doublons exactement

Question

j'ai écrit un script simple pygtk pour montrer des informations de processus de base dans un TreeView:

import gtk 
import os 
import pwd 
import grp 

class ProcParser: 
    """ 
    Parses the status file of a particular process 
    """ 
    def __init__(self, fname): 
     self.lines = map(lambda x: x[:-1], open(fname).readlines()) 

    def get_by_val(self, val): 
     for line in self.lines: 
      if line.startswith(val): 
       return line.split() 
     return [] 

class Proc: 
    """ 
    A process in the /proc filesystem 

    This class uses a ProcParser to determine it's own information 
    """ 
    def __init__(self, pid): 
     self.pid = int(pid) 
     self.parser = ProcParser("/proc/{0}/status".format(self.pid)) 
     self._from_file() 

    def _from_file(self): 
     self.uid = self.parser.get_by_val("Uid")[1] 
     self.gid = self.parser.get_by_val("Gid")[1] 
     self.name = self.parser.get_by_val("Name")[1] 
     self.user = pwd.getpwuid(int(self.uid)).pw_name 
     self.group = grp.getgrgid(int(self.gid)).gr_name 

class ProcTree: 
    "A tree that displays all running processes" 
    def __init__(self): 
     self.view = gtk.ScrolledWindow() 
     self.store = gtk.ListStore(str, int, str, str) 
     self.tree = gtk.TreeView(self.store) 
     self.cells = [ 
      gtk.CellRendererText(), 
      gtk.CellRendererText(), 
      gtk.CellRendererText(), 
      gtk.CellRendererText() 
     ] 
     self.tvcols = [ 
      gtk.TreeViewColumn("Name"), 
      gtk.TreeViewColumn("Pid"), 
      gtk.TreeViewColumn("User"), 
      gtk.TreeViewColumn("Group") 
     ] 

    def __call__(self): 
     return self.view 

    def config(self): 
     for col, cell in zip(self.tvcols, self.cells): 
      col.pack_start(cell, True) 
      col.add_attribute(cell, "text", 0) 
      self.tree.append_column(col) 
     self._update_store() 
     self.view.add_with_viewport(self.tree) 

    def show(self): 
     self.tree.show() 
     self.view.show() 

    def _update_store(self): 
     self.store.clear() 
     for item in os.listdir("/proc"): 
      try: pwid = int(item) 
      except: continue 
      pr = Proc(pwid) 
      self.store.append((pr.name, int(pr.pid), pr.user, pr.group)) 

class Window: 
    def __init__(self): 
     self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) 
     self.proctree = ProcTree() 

    def config(self): 
     self.proctree.config() 
     self.window.add(self.proctree()) 
     self.window.set_title("Process Viewer") 

    def show(self): 
     self.proctree.show() 
     self.window.show() 

    def run(self): 
     self.config() 
     self.show() 

win = Window() 
win.run() 
gtk.main() 

Mon problème est que toutes les valeurs des colonnes sont les mêmes.

Notes:

1. Apparemment, cela est en corrélation avec la première colonne (si je change la première des données de colonne, c'est ce que toutes les autres données deviennent)

(Ajoutera plus suggestions sont affichées)

pour append sur treview vous devriez faire

rendererText = gtk.CellRendererText() 
    tvcols = ["Name", "Pid", "User", "Group"] 

    for num, name in enumerate(tvcols): 
     column_name = gtk.TreeViewColumn(name ,rendererText, text=num) 
     self.tree.append_column(column_name)
