如何使用gtk.fileselection（python）过滤对路径的访问？

Question

我用 gtk.fileselection 工作，它工作得很好。但是如何使用文件选择小部件阻止对给定路径的访问。如果我不阻止对特定路径的访问，用户可以看到我系统中的敏感信息。

class FileSelection:
# Get the selected filename and print it to the console
def file_ok_sel(self, w):
    print "%s" % self.filew.get_filename()

def destroy(self, widget):
    gtk.main_quit()

def __init__(self):
    #Create a new file selection widget
    self.filew = gtk.FileSelection("File selection")
    self.filew.hide_fileop_buttons()
    self.filew.get_focus()


    self.filew.connect("destroy", self.destroy)
    # Connect the ok_button to file_ok_sel method
    self.filew.ok_button.connect("clicked", self.file_ok_sel)

    # Connect the cancel_button to destroy the widget
    self.filew.cancel_button.connect("clicked",lambda w: self.filew.destroy())

    # Lets set the filename, as if this were a save dialog,
    # and we are giving a default filename
    self.filew.set_filename("penguin.png")

    self.filew.show()

def main(self):
    gtk.main()
    print "selection"*10
    return 0

事实上，我只想允许访问从 "mnt/tnc/" 挂起的路径，不再允许访问。

 archivosTNC = os.listdir("/mnt/tnc")
    lista = []     
    for a in archivosTNC:
        if a[-2:] == ".H":
            lista.append(a)
        elif a[-4:] == ".txt":
            lista.append(a)
        elif a[-4:] == ".png":
            lista.append(a)
        elif a[-4:] == ".jpg":
            lista.append(a) 

    ventana = gtk.Window()
    ventana.set_default_size(-1, 300)
    scrolledWindow = gtk.ScrolledWindow()
    scrolledWindow.set_policy (hscrollbar_policy=gtk.POLICY_NEVER, vscrollbar_policy=gtk.POLICY_AUTOMATIC)
    ventana.add(scrolledWindow)
    tabla=table()
    vbox = gtk.VBox()
    tabla.attachToCell(vbox, col=1, row=1)
    scrolledWindow.add_with_viewport(tabla)

    #ventana.add(vbox)
    for item in lista:
        boton = gtk.Button(str(item))
        boton.connect('clicked', self.devolverNombreArchivo)
        vbox.pack_start(boton)
