update_idletasks() update_idletasks()函数与update()函数类似,也能更新GUI组件。但是,它只处理GUI界面中”空闲的任务”(idle tasks),即事件处理期结束后空闲的任务,它们常常是一些后台任务,比如文本框重绘。当我们运行一个程序,但不希望它阻塞GUI界面时,我们可以使用该函数更新GUI界面。 将上述代...
Tkinter: update_idletasks Jul 18 '05, 11:03 AM I'm confused about how to use the update_idletask s method. In my program, I have a handler for a button in which execution will linger. During that time, I would like for the GUI to continue to show signs of ...

execute any tasks currently in the event queue;update()runs tasks currently waiting in the queue until it's entirely clear, whileupdate_idletasks()only runs the idle tasks. This is generally less important and safer code, so it's recommended to useupdate_idletasks()unless it...
