Tkinter help, please...

[Medi Ochre]

I've been away from Python for some time, and I'm just starting to look
at Tkinter. Just so you know, I'm coming from Visual Basic, where this
would, I *think*, not have been a problem, so it must be a case of
getting my head around the Tkinter way of doing things.

In a nutshell, I've written an app wherein I wish to update the display
often. What's happening is that I get *no* display until main() hits
win.mainloop(). I've indicated the things I've tried (round about line
180). At the risk of exposing myself, here's the whole thing.

If you have a thought, I'd sure appreciate it!

Nick.

Re: Tkinter help, please...

I've made a couple of minor changes to your code from the Cribbage class
down:

class Cribbage:
def __init__(self, win):

self.parent = win # <---- make the toplevel Tk window an
# <---- attribute of the class
#Draw the interface
self.f = Frame(self.pare nt)
self.f.grid()
self.cardpix = [Label(self.f), Label(self.f), Label(self.f),
Label(self.f), Label(self.f)]
clr = ["red", "blue"]
n = 1
for c in self.cardpix:
c.configure(wid th=10, height=10, bg=clr[n%2], text="card
"+str(n))
c.grid(row=0, column=n-1)
n += 1
self.scorebox = Label(self.f)
self.scorebox.c onfigure(height =5, bg="green", text="Score: 0")
self.scorebox.g rid(row=1, column=0, columnspan=5)

def play(self):
d = Deck()
hand = [d.deal(), d.deal(), d.deal(), d.deal()]
flipped = d.deal()
hand.append(fli pped)
hand.sort()
score = tally(hand, flipped)
self.scorebox.c onfigure(text= "Score: " + str(score))
#Eventually, display the actual card images, but for now...
for c, x in zip(hand, self.cardpix):
x.configure(tex t = str(c))
#I've tried both of these, to no avail.
self.parent.upd ate() <---- update the toplevel window
return score

def main():
win = Tk()
run = Cribbage(win)
score = 0
best = 0
while score < 24:
score = run.play()
if score >= best: best = score
time.sleep(1) <--- short sleep to see what's happening
win.mainloop()

main()

John

Thank you, Mr. McMonagle!
