Use google to find the appropriate site, or browse this site, there
are plenty of examples. You may want to examine the code I wrote to
you to catch the idea:
#----------------------
import Tkinter
import pprint
tk = Tkinter.Tk()
f = Tkinter.Frame(tk, width=100, height=100)
msg = Tkinter.StringVar()
msg.set('Hello')
l = Tkinter.Label(f, textvariable=msg)
l.pack()
f.pack()
keys = set()
def keyPressHandler(event):
keys.add(event.char)
display()
def keyReleaseHandler(event):
keys.remove(event.char)
display()
def display():
msg.set(str(keys))
f.bind_all('<KeyPress>', keyPressHandler)
f.bind_all('<KeyRelease>', keyReleaseHandler)
f.mainloop()
