Hi, I'm stumped on how to accomplish event handling with a Tkinter app
that's a class. I didn't find anything on a Dejanews search either...can
anybody tell me what the following example is doing wrong?

from Tkinter import *

class gui(Frame):
  def __init__(self, parent=None):
    Frame.__init__(self, parent)
    self.grid()
    self.bind("<Key>", self.callback)
    self.str = ""
    self.mainloop()

  def callback(self, event):
    print event.char
    self.str = self.str + event.char

g = gui()

-----
Any help is appreciated. I'm stuck.

Thanks,

Brian
