Tkinter线程

Question

尽管看到许多关于这个话题的问题被问到，我还是找不到一个合适的答案来解决我的困惑。我是Python的初学者，它是我的第一语言。我正在尝试创建一个对话框，该对话框在打开对话框时自动运行测试。当测试完成时，我希望打开另一个对话框，其中显示测试已完成。测试工作正常，运行正常。但是，由于辅助对话框调用的是Tk()的第二个实例，因此它不会打开。

我的问题是:如何更改代码，以便在测试完成时打开辅助对话框？

obj_rcs是正在运行的测试。obj_config是第二个对话框。

我的代码：

from slice_setup import SLICE_SETUP
import Tkinter

import Queue

class GuiPart:

    def __init__(self, master, queue):
        self.queue = queue
        master.geometry("300x100+400+250")
        master.title("RSAM BCT")
        Tkinter.Label(master, text= "REDCOM SLICE", fg="red").pack()
        Tkinter.Label(master, text= "BCT - Basic Configuration Test",    
        fg= "red").pack()
        Tkinter.Label(master, text= "Please wait...", fg= "black").pack()
        Tkinter.Label(master, text= "Estimated time: 3 min 6 sec", 
        fg= "black").pack()


    def processIncoming(self):
        while self.queue.qsize():
            try:
                msg = self.queue.get(0)
                print msg
            except Queue.Empty:
                pass

class ThreadedClient:

    def __init__(self, master):
        self.master = master
        # Create the queue
        self.queue = Queue.Queue()
        # Set up the GUI part
        self.gui = GuiPart(master, self.queue)
        # Set up the thread to do asynchronous I/O
        self.running = 1
        self.thread1 = threading.Thread(target = self.workerThread1)
        self.thread1.start()
        self.periodicCall()

    def periodicCall(self):
        self.gui.processIncoming()
        if not self.running:
            import sys
            sys.exit(1)
        self.master.after(100, self.periodicCall)

    def workerThread1(self):
        while self.running:
            obj_rcs = SLICE_SETUP()
            obj_com = complete()

            obj_rcs.SLICE()
            obj_com.config()

root = Tkinter.Tk()
client = ThreadedClient(root)
root.mainloop()

class complete:

    def config(self):
        Tkinter.geometry("400x300+400+250")
        Tkinter.title("RSAM BCT")
        Tkinter.Label(master, text= "REDCOME SLICE", fg="red").pack()
        Tkinter.Label(master, text= "BCT - Basic Configuration Test", fg= "red").pack()
        Tkinter.Label(master, text= "Configuration Complete!", fg= "dark green").pack()
        Tkinter.Label(master, text= "Trunk 1: Port 1: Phone 1: 760-450-4500", 
        fg= "black").pack()
        Tkinter.Label(master, text= "Trunk 1: Port 2: Phone 2: 760-450-4501", 
        fg= "black").pack()
        Tkinter.Button(master, text = "    Exit    ", 
        command = Tkinter.destroy).pack()

看起来问题在于，当您调用其他模块中的函数时，您正在创建另一个Tk元素，因为您没有将您创建的元素传递给complete()函数。因此，它应该接受一个master参数，然后在另一个模块中使用它，然后避免多个根Tk元素。

此外，您正在使用多个几何管理器(place和pack)。您应该在同一窗口中只使用一个，以避免意外行为。此外，这些方法总是返回None，所以像plabel = ...这样的赋值是无用的--不仅因为它存储None，还因为它可能具有误导性。

编辑:我对你的代码进行了修改，这样你就可以大致了解如何与spawn线程进行通信了。我还没有测试过它，但至少它可以作为一个参考，以获得大致的想法。
