添加进度组件

python 复制代码

def download():          
            # 创建下载进度框
            progress_window = tk.Toplevel()
            progress_window.title("下载进度")
            progress_label = tk.Label(progress_window, text="正在下载视频文件...")
            progress_label.pack(pady=10)
            progress_bar = ttk.Progressbar(progress_window, orient="horizontal", length=300, mode="determinate")
            progress_bar.pack(pady=10)

            # 获取窗口宽高并居中显示
            progress_window.update_idletasks()
            window_width = progress_window.winfo_width()
            window_height = progress_window.winfo_height()
            screen_width = progress_window.winfo_screenwidth()
            screen_height = progress_window.winfo_screenheight()
            x = (screen_width - window_width) // 2
            y = (screen_height - window_height) // 2
            progress_window.geometry(f"{window_width}x{window_height}+{x}+{y}")

创建进度更新方法

python 复制代码

def update_progress(progress):
                progress_bar['value'] = progress
                progress_window.update_idletasks()

调用下载方法，传入进度更新方法

python 复制代码

ls_setoption.get_dump_video(video_dir, progress_callback=update_progress)

progress_window.destroy()

使用子线程调用下载方法，注意用子线程，否则下载过程UI会卡死，进度不更新
python 复制代码
```
    download_thread = threading.Thread(target=download)
    download_thread.start()
```
