如何使用按钮关闭窗口？

<button onclick="closeWindow()">关闭窗口</button>

function closeWindow() {
    window.close();
}

private void closeButton_Click(object sender, EventArgs e)
{
    this.Close();
}

private void closeButtonActionPerformed(java.awt.event.ActionEvent evt) {                                           
    this.dispose();
}

import tkinter as tk

def close_window():
    root.destroy()

root = tk.Tk()
button = tk.Button(root, text="关闭窗口", command=close_window)
button.pack()
root.mainloop()
