[Tutor] Continuously Updating A Display?

[BELSEY, Dylan]

Alternatively, try the "after" method on widgets.  This creates a callback
to a user defined function after a preset period of time.  Note: Only
referring to Tkinter at the moment.

Normally I'd do that with a label widget and just update the text 
from various points in my program. 


class TkinterApp(Frame):
   def __init__(self):
      self.MsgBrd = Label(self)
      self.MsgBoard.pack()
      # etc
   def another(self):
      # do some stuff
      self.MsgBrd['text'] = "I'm doing another thing!"
      # do some more

TkinterApp().mainloop()


Does that help?
