[gtkmvc-users] How to launch one view from another view

[haiyan qu <quh...@gm...>]

Greeting, I am a beginner of pygtkmvc. So this may be a dumb question.

I am trying to convert all pygtk-demo examples to pygtkmvc framework,
I believe this will be my best practice for learning pygtkmvc.

I have a problem when I am converting pygtk-demo->Dialog&MessageBox.
This example involved 2 dialogs, parent dialog will launch child
dialog. I created both parent and child dialog in Glade as “window1”
and “window2”
When I try to launch “window2” from the main window “window1”, I
didn't get “window2”, instead I got a duplicate “window1”.

Below are my 2 views from same .galde file, different top.
class MyView1 (View):
    builder = "test.glade"
    top = 'window1'

class MyView2 (View):
    builder = "test.glade"
    top = 'window2'

When I click a button from view1, I want to launch view2.
Unfortunately, view1 is opened again.
    def on_button_dialog_clicked(self, user_data):
        v2 = MyView2()
        c2 = MyControllerAdap2(self.model, v2)

Any comment is very appreciated!
example code (main.py and test.glade) is attached.
demo.py is the original code from pygtk-demo (without using pygtkmvc framework)

Thanks in advance and best regards!
