tkinter 文本小部件无法出现在所需的窗口上

Question

所以我编写了一个简单的 tkinter gui，它会在出现提示时显示一些命令输出结果，我遇到的唯一问题是该命令不会出现在任何其他屏幕上。

def updateipt():
    text = Text(main_window, height=150, width=124)
    text.pack()
    with Popen(["iptables", '-L', '-v', '-n'], stdout=PIPE, stderr=PIPE) as p:
        for line in p.stdout:
            text.insert(END, line,)

text = Text(main_window, height=150, width=124)

我假设用另一个窗口替换上面的 main_window 参数会将文本小部件定向到另一个窗口，但每次我尝试这个我都会收到一个错误，指出窗口需要 Tk(): AttributeError: 'function'对象没有属性“tk”

我该如何解决这个问题？

完整代码贴在下面：

main_window()

Answer 1

在您的代码中，您的函数名称是也是您的窗口名称（顶层）。请更改所有函数名称。此外，在您的 updateipt 函数中，您提供了一个放置 Text 小部件的函数，因此它会引发错误。
