  from gi.repository import Gtk

import sys

class MyApplication(Gtk.Application):

    def do_activate(self):

        # create a Gtk Window belonging to the application itself

        window = Gtk.Window(application=self)

        # set the title

        window.set_title("Welcome to GNOME")

        # show the window

        window.show_all()

# create and run the application, exit with the value returned by

# running the program

app = MyApplication()

exit_status = app.run(sys.argv)

sys.exit(exit_status)

  <list>

    <item>
set_default_size(200, 100) sets the default size of the window to a width of 200 and a height of 100; if instead of a positive number we pass -1 we have the default size.
</item>

    <item>
set_position(Gtk.WindowPosition.CENTER) centers the window. Other options are Gtk.WindowPosition.NONE, Gtk.WindowPosition.MOUSE, Gtk.WindowPosition.CENTER_ALWAYS, Gtk.WindowPosition.CENTER_ON_PARENT.
