How to quit a dialog within a function ?

[amskape]

Dear Friends,
I am working in a python based application. I need an option to go
a page with Dialog >> combobox option. But I could not close the dialog box on the onchange event of combobox. My current function is:

  def mostrar_combobox(self, titulo, texto_etiqueta, lista):
    """
    MÃ © All to show a combobox on screen and get the option chosen
    """
    #print texto_etiqueta
    #dialogo = gtk.Dialog(titulo, None, 0, (gtk.STOCK_OK, gtk.RESPONSE_OK, gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL))
    dialogo = gtk.Dialog(titulo, None, 0, None)
    etiqueta = gtk.Label(texto_etiqueta)
    etiqueta.show()
    dialogo.vbox.pack_start(etiqueta)
    combobox = gtk.combo_box_new_text()
    for x in lista:
      combobox.append_text(x)
    combobox.connect('changed', self.changed_cb)
    #combobox.set_active(0)
    combobox.show()
    dialogo.vbox.pack_start(combobox, False)
    dialogo.run()
    elemento_activo = combobox.get_active()
    dialogo.destroy()
    
    return elemento_activo

Please advise

Thanks

dialogo.destroy () should be in the callback function self.changed_cb (which we don't have so can't comment further).

dear dwlabs,
When I give that option in 'changed_cb' as below:

  def mostrar_combobox(self, titulo, texto_etiqueta, lista):
    """
    MÃ © All to show a combobox on screen and get the option chosen
    """
    #print texto_etiqueta
    #dialogo = gtk.Dialog(titulo, None, 0, (gtk.STOCK_OK, gtk.RESPONSE_OK, gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL))
    dialogo = gtk.Dialog(titulo, None, 0, None)
    etiqueta = gtk.Label(texto_etiqueta)
    etiqueta.show()
    dialogo.vbox.pack_start(etiqueta)
    combobox = gtk.combo_box_new_text()
    for x in lista:
      combobox.append_text(x)
    combobox.connect('changed', self.changed_cb)
    #combobox.set_active(0)
    combobox.show()
    dialogo.vbox.pack_start(combobox, False)
    dialogo.run()
    #print response
    #combobox.connect('changed', self.changed_cb)
    elemento_activo = combobox.get_active()
    
    #dialogo.destroy()
    dialogo.hide()
    return elemento_activo
 
  def changed_cb(self, combobox):
    model = combobox.get_model()
    index = combobox.get_active()
    #self.dialogo.destroy()
    if index:
      self.dialogo.destroy()
      print index
      return index

got error as

self.dialogo.de stroy()
AttributeError: Controlador instance has no attribute 'dialogo'

So need an intelligent solution , waiting for it. In my opinion if I remove that 'changed_cb' def no problem in current working of program . That function is really useless ...

Thanks

The only thing I can do is point you to a tutorial on classes as there are too many things that you don't understand http://www.freenetpages.co.uk/hp/ala...d/tutclass.htm

Dear dwlabs and friends,
I try your code , but still have no solution :(
my code is:

 def mostrar_combobox(self, titulo, texto_etiqueta, lista):
    """
    MÃ © All to show a combobox on screen and get the option chosen
    """
    #print texto_etiqueta
    #dialogo = gtk.Dialog(titulo, None, 0, (gtk.STOCK_OK, gtk.RESPONSE_OK, gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL))
    dialogo = gtk.Dialog(titulo, None,  gtk.DIALOG_MODAL, None)
    dialogo.connect('response', lambda *x: self.destroy())
    etiqueta = gtk.Label(texto_etiqueta)
    etiqueta.show()
    dialogo.vbox.pack_start(etiqueta)
    combobox = gtk.combo_box_new_text()
    for x in lista:
      combobox.append_text(x)
    combobox.connect('changed', self.changed_cb)
    combobox.show()
    dialogo.vbox.pack_start(combobox, False)
    response = dialogo.run()
    combobox.connect('changed', self.changed_cb)
    dialogo.emit("delete-event", gtk.gdk.Event(gtk.gdk.DELETE))
    elemento_activo = combobox.get_active()
    return elemento_activo
    
 
  def changed_cb(self, combobox):
    #model = combobox.get_model()
    index = combobox.get_active()
    #self.dialogo.destroy()
    #response = self.dialogo.run()
    if index > -1:
      print index
    
      #return index

Do i have use GtkWindow for this purpose ? if so please provide a sample code..
