[HELP] Tkinter Application Minimized to System Tray :)

[陈 阳]

  I write a program with Python 2.4 + Tkinter
    Execute it, there will be a window show something.
    If I minimize it, it will be minimized to the taskbar. But I would like 
it to miniminze to the System Tray, this can make taskbar more clear. Would 
you please tell me how to modify my program.

    Thanks a lot !!

Soure Code : 

# Display digits of pi in a window, calculating in a separate thread.
# Compare with wpi.py in the Demo/threads/wpi.py

import sys
import time
import thread
from Tkinter import *

class ThreadExample:
    def __init__(self, master=None):
        self.ok                = 1
        self.digits            = []
        self.digits_calculated = 0
        self.digits_displayed  = 0
        self.master            = master

        thread.start_new_thread(self.worker_thread, ())

        self.frame = Frame(master, relief=RAISED, borderwidth=2)
        self.text = Text(self.frame, height=26, width=50)
        self.scroll = Scrollbar(self.frame, command=self.text.yview)
        self.text.configure(yscrollcommand=self.scroll.set)
        self.text.pack(side=LEFT)
        self.scroll.pack(side=RIGHT, fill=Y)
        self.frame.pack(padx=4, pady=4)
        Button(master, text='Close', command=self.shutdown).pack(side=TOP)

        self.master.after(100, self.check_digits)

    def worker_thread(self):
        while self.ok:
            self.digits.append(`9`)
            time.sleep(0.001)

    def shutdown(self):
        self.ok =0
        self.master.after(100, self.master.quit)

    def check_digits(self):
        self.digits_calculated = len(self.digits)
        diff = self.digits_calculated - self.digits_displayed
        ix = self.digits_displayed
        for i in range(diff):
            self.text.insert(END, self.digits[ix+i])
        self.digits_displayed =  self.digits_calculated
        self.master.title('%d digits of pi' % self.digits_displayed)
        self.master.after(100, self.check_digits)

root = Tk()
root.option_readfile('optionDB')
example = ThreadExample(root)
root.mainloop()
