[pygtk] tutorial

[Christopher Spears]

I am working on this tutorial:

http://www.learningpython.com/2006/05/07/creating-a-gui-using-pygtk-and-glade/

As I progress throught the tutorial, I create a gui
with glade that contains a button that prints "Hello
World!" when I click it.  Here is the python code from
the tutorial:

#!/usr/bin/env python

import sys
try:
 	import pygtk
  	pygtk.require("2.0")
except:
  	pass
try:
	import gtk
  	import gtk.glade
except:
	sys.exit(1)

class HellowWorldGTK:
	"""This is an Hello World GTK application"""

	def __init__(self):
		
		#Set the Glade file
		self.gladefile = "pyhelloworld.glade"  
	        self.wTree = gtk.glade.XML(self.gladefile) 
		
		#Create our dictionay and connect it
		dic = { "on_btnHelloWorld_clicked" :
self.btnHelloWorld_clicked,
			"on_MainWindow_destroy" : gtk.main_quit }
		self.wTree.signal_autoconnect(dic)

	def btnHelloWorld_clicked(self, widget):
		print "Hello World!"


if __name__ == "__main__":
	hwg = HellowWorldGTK()
	gtk.main()

The Hello World button works.  When I quit the gui by
pressing on the red button in the upper right, the gui
vanishes, but the process continues to run.

I tried to solve this problem by using glade to attach
the destroy_event to on_MainWindow_destroy and then
running the script again.  However, the fix did not
work!  

Has anyone else had similar problems with this tutorial!?
