    button = tk.Button(popup, text="关闭", command=popup.destroy)
    button.pack(pady=10)

# 主窗口

    # 使弹窗成为模态窗口
    popup.transient(root)  # 关联到主窗口
    popup.grab_set()       # 捕获所有事件
    
    label = tk.Label(popup, text="这是模态弹窗")
    label.pack(pady=20)
    
    def close_popup():
        popup.grab_release()  # 释放事件捕获
        popup.destroy()
    
    button = tk.Button(popup, text="关闭", command=close_popup)
    button.pack(pady=10)

root = tk.Tk()
root.title("主窗口")

modal_button = tk.Button(root, text="打开模态弹窗", command=create_modal_popup)
modal_button.pack(pady=50)

root.mainloop()

    popup.title("输入弹窗")
    popup.geometry("300x150")
    
    label = tk.Label(popup, text="请输入内容:")
    label.pack(pady=10)
    
    entry = tk.Entry(popup, width=30)
    entry.pack(pady=10)
    
    submit_btn = tk.Button(popup, text="提交", command=return_input)
    submit_btn.pack(pady=10)
    
    # 等待弹窗关闭
    popup.wait_window()
    return user_input

root = tk.Tk()

        progress_bar['value'] = i
        progress_bar.update()
    time.sleep(1)
    popup.destroy()

def show_progress():
    popup = tk.Toplevel()
    popup.title("进度")
    popup.geometry("300x100")
    
    label = tk.Label(popup, text="处理中，请稍候...")
    label.pack(pady=5)
    
    progress_bar = ttk.Progressbar(popup, orient="horizontal", length=250, mode="determinate")
    progress_bar.pack(pady=10)
    
    # 在新线程中运行任务
    thread = threading.Thread(target=long_running_task, args=(progress_bar, popup))
