Hi Adam!

I'm not a Tkinter expert, so I probably cannot provide
the best solution for your problem.
Nevertheless I tried two corrections, which adress your
problem seeminly successfully

This is because of


in createWidgets. Here you don't assign the method pintentry
to command, but the result of executing this method. (So it is
ececuted, when createWidget is called, but not when the command
is executed.


	self.save2Button = Button(self, text = "Submit",


	def printentry(self):
		print "ok - the submit has been pressed - \
                        I need to get  it's value"
		print self.content.get()

self.destroy destroys the frame, not the root window.


	def exiting(self):
		if tkMessageBox.askokcancel("Quit",
                                        "Do you really wish to quit?"):

I'm not sure if this is the canonical way of exiting a
Tkinter-App :-(   (Perhaps somebody knows more.)

Hope this helps,
