class MyWindow(Gtk.ApplicationWindow):

  <title>Useful methods for a Gtk.ApplicationWindow widget</title>

  <list>
    <item><p><code>set_default_size(200, 100)</code> sets the default size of the window to a width of <code>200</code> and a height of <code>100</code>; if instead of a positive number we pass <code>-1</code> we have the default size.</p></item>
    <item><p><code>set_position(Gtk.WindowPosition.CENTER)</code> centers the window. Other options are <code>Gtk.WindowPosition.NONE, Gtk.WindowPosition.MOUSE, Gtk.WindowPosition.CENTER_ALWAYS, Gtk.WindowPosition.CENTER_ON_PARENT</code>.</p></item>
