How to delete the widgets from the window?

推荐答案

您可以调用pack_forget 删除小部件(如果您使用 pack将其添加到窗口中).

You can call pack_forget to remove a widget (if you use pack to add it to the window).

示例:

from tkinter import *

root = Tk()

b = Button(root, text="Delete me", command=lambda: b.pack_forget())
b.pack()

root.mainloop()

如果您使用 pack_forget，您可以稍后再次调用 pack 再次显示小部件.如果您想永久删除它，请在小部件上调用 destroy(然后您将无法重新添加它).

If you use pack_forget, you can later show the widget again calling pack again. If you want to permanently delete it, call destroy on the widget (then you won't be able to re-add it).

如果您使用 grid 方法，您可以使用 grid_forget 或 grid_remove 以隐藏小部件.

If you use the grid method, you can use grid_forget or grid_remove to hide the widget.
