Hi,
Firstly, on a conceptual note, "self.window" is not really an accurate
name for the glade.XML object created. It does not represent any one
window, but rather the whole GUI (windows and widgets) created in Glade.
You can see the glade.XML object as a factory object, taking the XML
output from the Glade UI designer ("check.glade" in your case) as input
and giving you the constructed widgets as output.
Having said that, there is no way for the glade.XML object to know about
widgets that were created at run-time and not specified in its input XML
and that is why self.window.get_widget("test") returns None. Also the
string you passed as argument to gtk.CheckButton() is the button's label
and not it's name. The difference is that the label is the string that
is displayed on the button and the name is used as an internal string
identifier for the widget.
The most common way to achieve what you are trying to do here, is to
keep a reference to all new, custom-created widgets. So if you replace
"button = gtk.CheckButton('test')" with "self.button =
gtk.CheckButton('test')", you can simply do "state =
self.button.get_active()" in your "button2_clicked()" event handler.
