The example that you sent contains the answer.  If you look at your
callback methods the parameter that is passed is the data from glade.
For example, in the method mapped to the click event for button one:

	public void on_digitButton1_clicked(Object button)

If you put the value "1" in the "Data" field in the signal tab in glade
then the Object button actually is the value 1.  If you execute

System.out.println(button.toString())

It will print "1".  What you can do is map all of your numeric buttons to
the same callback that knows how to deal with numbers passing the value 
that is the label.  Map your operator buttons to a signal callback that 
understands how to deal with operators.
