Python TKInter 破坏不工作

Question

我正在尝试使用 self.win.destroy 关闭 TKInter 窗口。

将事件绑定(bind)到按钮时会抛出以下错误:

...
Can't invoke "bind" command: application has been destroyed
During handling the above exception, another exception occured:
...
Can't invoke "destroy" command: application has been destroyed

如何将“关闭窗口”命令绑定(bind)到按钮？

Answer 1

这样做:

button['command'] = root_window.destroy # give it the function
# when the button is pressed the call () is done

不要这样做:

button.bind('<Button-1>', root_window.destroy()) # () makes the call

因为

root_window.destroy()

在调用 button.bind 之前销毁窗口。

这也是错误的:但不会破坏根窗口:

button.bind('<Button-1>', root_window.destroy)

因为

• 不能用键盘触发按钮
• root_window.destroy(event) 被调用，但 root.destroy() 只接受一个参数。

这也行:

button.bind('<Button-1>', lambda event: root_window.destroy())
