[Tutor] How to insert a quit-Button in a Tkinter class?

[Karim]

Hello,

Inherit from Frame see below:

from Tkinter import *

class App(Frame):
     def __init__(self, master=None):
         Frame.__init__(self, master)
         self.grid()
         self.createLabel()
         self.createButton()

     def createLabel(self):
         self.label = Tkinter.Label(text="")
         self.label.grid()
         self.update_clock()

     def update_clock(self):
         now = time.strftime("%H:%M:%S")
         self.label.configure(text=now)
         self.after(1000, self.update_clock)

     def createButton(self):
         self.quitButton = Button( self, text='Quit', command=self.quit )
         self.quitButton.grid()

app = App()
app.master.title("Clock Time!")
app.mainloop()

Regards
Karim
