解决tkinter卡死问题
时间：2023-01-27 02:30:00
参考https://blog.csdn.net/qq_41204464/article/details/86707216
核心思路:
1.引入threading库
import threading2.在界面回调函数中添加装饰器
# 包装进线程(耗时操作) @staticmethod def thread_it(func, *args): t = threading.Thread(target=func, args=args) t.setDaemon(True) # 保护-即使主界面关闭，线程也会留在后台运行(不对！） t.start() # 启动 # t.join() # 阻塞--会卡死界面！以我写的为基础tkinter做界面，然后百度关键词爬图程序。有日志调试，界面不卡
