Gtk.builder() And Multiple Glade Files Breaks

I have a glade gui, and I want to insert another object using a glade file as well. When I do it as bellow (this is essentially what I am doing) the whole app hangs and the self.

Solution 1:

Is there a good reason for using the same gtk.Builder object in two classes? This might be the cause of your problem. In your one class, you load a glade file but you never do anything with its widgets. Something like this should work:

classone(gtk.VBox):

  def__init__(self):
    gtk.VBox.__init__(self)
    self.builder = gtk.Builder()
    self.builder.add_from_file("ui_for_one.glade")
    some_widget = self.builder.get_object("some_widget")
    self.add(some_widget)
    self.builder.connect_signals(self)
    # No reason to call self.show() here, that should be done manually.#Your callback functions hereclasstwo(object):  # This is the page in a notebook.   def__init__(self):
    self.builder = gtk.Builder()
    self.builder.add_from_file("ui_for_two.glade")
    self.some_container = self.builder.get_object("some_container")
    self.one = one()
    self.some_container.pack_start(self.one, False, False)
    self.some_container.show_all() #recursively show some_container and all its child widgets

    self.builder.connect_signals(self)
