Question

您好我是python tkinter编程的新手。我正在尝试关闭当前窗口。但是，当我点击退出所有窗口，包括主要退出。我正在使用currrentwindow.destory（），但它关闭了所有。

def dic_winn3():
    DicWin = tk.Toplevel(root)
    DicWin.title('operations')
    DicWin.geometry('300x300')
    DicWinButton.config(state='normal')
    L1 = Label(DicWin, text="country")
    L1.pack()
    E1 = Entry(DicWin, bd =20)
    E1.pack()

感谢您的帮助。

您正在关闭应用程序而不是窗口。您需要在要关闭的单个窗口上调用destroy。在你的情况下，最简单的方法是使用lambda：

B5 = tk.Button(DicWin, text='quit', command=lambda win=DicWin:win.destroy)

你应该能够解决这个问题：

    B5 = tk.Button(DicWin, text='quit', command=lambda :DicWin.destroy)

但是，小心谨慎总是好的。根据您最终要做的事情，这可能会导致新手出现非常混乱的错误（请参阅here和here）。

然后您可以摆脱close_window功能。

编辑：

下面的每个@fhdrsdg更正 - 这里不需要lambda：

    B5 = tk.Button(DicWin, text='quit', command=DicWin.destroy)

如何在不退出其他窗口的情况下在python tkinter中设计退出当前窗口方法？
