在Python中的Tkinter.Tk窗口时，可以为清除任务覆盖哪种方法？ [英] Which method can I override for cleanup task when a Tkinter.Tk window in Python?

问题描述

class MainGUI(Tkinter.Tk):
    # some overrides

# MAIN 

gui = MainGUI(None)
gui.mainloop()

但是当窗口位于由用户关闭。我可以重写Tkinter.Tk中的哪个方法？

But I need to do some cleanup when the window is closed by the user. Which method in Tkinter.Tk can I override?

推荐答案

您可以设置一个绑定，该绑定在窗口销毁时会触发。绑定到< Destroy> 或为WM_DELETE_WINDOW添加协议处理程序。

You can set up a binding that gets fired when the window is destroyed. Either bind to <Destroy> or add a protocol handler for WM_DELETE_WINDOW.

例如：

def callback():
    # your cleanup code here

...
root.protocol("WM_DELETE_WINDOW", callback)
