Tkinter binding and keyboard hardware settings (WinXP)

[apriebe47]

Hello,

I have created a simple canvas in Tkinter to display a number of
PhotoImages, I then bind a key (in my case, <Up>) to start a loop that
plays through a list of PhotoImages to make it an animation of sorts.
What I noticed is, after holding down the key for a certain time, it
would not loop through all 6 animations, instead it would just go
through the first 2 and reset it self. I changed the key bind to
Button-1 and did not encounter this problem. I then went into my
keyboard hardware settings and changed the repeat rate to the longest
delay and the repeat delay to the longest delay. This improved it some
what, but I don't think it is practical to do this everytime I start up
the program. My question is, is there a way to bind a key so as to make
it ignore the keyboard's delay and repeat rate settings? Here's the
code just so you can get an idea:

# GIF Animation Test

from Tkinter import *
from time import sleep

class GIF:
def __init__(self, root):
self.root = root
self.canvas = Canvas(root, bg="white", width=225, height=200)
self.canvas.pac k()
self.cronoUpIma geList =[
"cronoup1.g if", "cronoup2.g if", "cronoup3.g if",
"cronoup4.g if", "cronoup5.g if", "cronoup6.g if"]
self.gifImage = PhotoImage(file =self.cronoUpIm ageList[0])
self.cronoDefUp = PhotoImage(file ="cronodefup.gi f")
self.drawImage = self.canvas.cre ate_image(112.5 , 100, image=
self.cronoDefUp )
self.canvas.bin d("<Up>", self.keyboardPr sUp)
self.canvas.bin d("<Down>", self.keyboardRl sUp)

def keyboardPrsUp(s elf, event):
self.canvas.del ete(self.drawIm age)
self.counter = 0
self.killEvent = False
while self.killEvent != True:
print self.cronoUpIma geList[self.counter]
self.gifImage =
PhotoImage(file =self.cronoUpIm ageList[self.counter])
self.drawImage = self.canvas.cre ate_image(112.5 , 100,
image=
self.gifImage)
self.counter = self.counter + 1
if self.counter 5:
self.counter = 0
self.canvas.upd ate()
sleep(.05)
def keyboardRlsUp(s elf, event):
self.counter = 0
self.killEvent = True
self.canvas.del ete(self.drawIm age)
self.drawImage = self.canvas.cre ate_image(112.5 , 100, image=
self.cronoDefUp )
root = Tk()
root.title("GIF Animation Test")
app = GIF(root)
root.mainloop()

root.title("GIF Animation Test")
app = GIF(root)
root.mainloop()

What about simple tracking of time (see above NOT tested rough draft) in
the keyboardPrsUp and keyboardRlsUp functions, so, that events raised
earlier than after a specified delay period will just become ignored?
