问题描述
当用户presses一个的关闭的按钮我创建一些任务退出前执行。但是，如果用户点击窗口右上角的 [X] 按钮关闭该窗口，我不能执行这些任务。
When the user presses a close Button that I created, some tasks are performed before exiting. However, if the user clicks on the [X] button in the top-right of the window to close the window, I cannot perform these tasks.
我怎么可以重写会发生什么，当用户点击 [X] 按钮？
How can I override what happens when the user clicks [X] button?
推荐答案
听起来好像你保存窗口应该是。
It sounds as if your save window should be modal.
如果这是一个基本保存窗口，你为什么要重新发明轮子？塔卡有的用于这一目的。
If this is a basic save window, why are you reinventing the wheel?Tk has a tkFileDialog for this purpose.
如果你想要的是覆盖销毁窗口的默认行为，你可以简单地做：
If what you want is to override the default behaviour of destroying the window, you can simply do:
root.protocol('WM_DELETE_WINDOW', doSomething) # root is your root window
def doSomething():
# check if saving
# if not:
root.destroy()
此方式，可以拦截的destroy（）打电话时，有人关闭窗口（通过任何方式），做你喜欢的事情。
This way, you can intercept the destroy() call when someone closes the window (by any means) and do what you like.
