A smallish Tkinter question

[Miki Tebeka]

Hello Nick,

> """
> What I want: A little window to open with a 0 in it. Every second, the
> 0 should increment by 1.
> What I get: A one second delay, see the window with a 1 in it, and then
> nothing appears to happen. Never see the 0, never see a 2.  Any quick
> clues? Thanks. Nick. (Python 2.4, Win98).

from Tkinter import *

class Clock(Frame): #<<<
    def __init__(self, parent):
        Frame.__init__(self, parent) #<<<
        self.time = 0
        self.display = Label(parent)
        self.display["font"] = "Arial 16"
        self.display["text"] = str(self.time)
        self.display.pack()

    def run(self): #<<<
        self.loop()

    def loop(self): #<<<
        self.time = self.time + 1
        self.display["text"] = str(self.time)
        self.after(1000, self.loop)

win = Tk()
app = Clock(win)
app.run() #also tried run(win) with self,parent above
win.mainloop()

HTH.
