I have played around with python for a while, and I thought I'd try the Tkiner window API. But something in my program causes python to hang and as far as I can tell, it's a call to Tk.quit that makes it hang.
I used this [link=http://www.pythonware.com/library/tkinter/introduction/hello-again.htm]guide
as[/link] a template for my program
I use IDLE with python 2.7 on a MacBook 2.1 with Mac OS X 10.5.5 as my programming environment.
Here's the source code:
from Tkinter import *
def __init__(self, master):
frame = Frame(master)
self.txt = Entry(frame)
self.button = Button(frame, text="Print", command=frame.quit)
root = Tk()
app = App(root)
Please, if anyone knows why my program hangs, reply.
 I think it's IDLE that's causing the problem. When I run the program in the terminal it does not hang. [/edit]
