Includere il file di glade nello script

Niente di piu' semplice. Basta dichiare una variabile e incollarci dentro l'xml di glade. 

gui='''
<?xml version="1.0" encoding="UTF-8"?>
<!-- Generated with glade 3.20.2 -->
<interface>
  <requires lib="gtk+" version="3.18"/>
  <object class="GtkWindow" id="window">
 ...(continua)...
'''

e poi caricare la gui con 

self.add_from_string(gui)
