Question

您好我尝试在tkinter中使用toplevel方法，但它没有工作...... 我应该写两个方法在不同的时间打开两个窗口，而有方法并行运行？决定哪种方法与接收方法并行运行...代码卡在＆＃34; window = Toplevel（root）＆＃34;的接收方法中。当然它得到了一条消息，但我不想让你们溢出......

from Tkinter import *
import threading


def decide_what(self):

    global root
    root = Tk()

    root.title("options")
    root.geometry("600x250")
    root.resizable(width=FALSE, height=FALSE)  # cant resize

    self.label = Label(root, text='CHOOSE YOUR FIRST OPTION!', font=30)
    self.label.place(x=200, y=13)

    self.button1 = Button(root, text='PrivateChat', font=30, 
    command=self.private)
    self.button1.place(x=1, y=50, width=200, height=199)

    self.button2 = Button(root, text='GroupChat', font=30, 
    command=self.group)
    self.button2.place(x=201, y=50, width=199, height=199)

    self.button3 = Button(root, text='BroadCast', font=30, 
    command=self.broadcast)
    self.button3.place(x=400, y=50, width=200, height=199)

    self.button4 = Button(root, text='WAIT', font=30, command=self.wait)
    self.button4.place(x=500, y=10)

    root.mainloop()


def receiving_message(self):  # a function that responsible to receive a message from the server, **shes in a class**

    print "receive??????????????????"
    while True:

        data = self.sock.recv(1024)

        data = decryption(data)
        print "data", data

        if data[:2] == "Br":

            print "got into br"

            window = Toplevel(root)
            print "window V"

            window.title("BroadCastZone")
            label = Label(window, text=data)
            label.pack()
            button = Button(window, text="ok", command=window.destroy)
            button.pack()

            print data

所有tkinter代码都需要在同一个线程中运行。如果receiving_message在单独的线程中运行，则无法创建Toplevel的实例。它需要向主线程发送消息并要求它打开一个窗口。

我怎样才能使用Toplevel方法？
