Hello, I asked for help in another location and it solved my problem,
but the only problem is I don't fully understand the after function.
Here is part of the code that was given to me.
def print_label_slowly(self, message):
'''Print a label one character at a time using the event loop'''
t = self.label.cget("text")
t += message[0]
self.label.config(text=t)
if len(message) > 1:
self.after(500, self.print_label_slowly, message[1:])
I understand it, and the gist of how it works, but the self.after... I
can not find any documentation on it (because after is such a common
word), so can you guys tell me how it works. Is this a built in
function (didn't see it on the built in function list)? Does it always
take 3 arguements? Is this a user made function and I'm just
overlooking where it was defined at?
The function you have shown there appears to be a class method.
self.after means you are calling another method of the same function
that print_label_slowly is a part of.
Do you have the rest of the code? If you're still confused post it and
hopefully we can clear it up for you.
HTH,
Adam.
