这是我的错误。
TclError: unknown option "-borderwidth"
错误来自此行
self._button.config( width=1, height=1, borderwidth = 0)
我也曾尝试过]
self._button = ttk.Button(self,command = self._activate, width=1, height=1, borderwidth = 0)存在相同错误。
我已经删除了borderwidth，然后在width / height上引发了相同的错误。我已经在其他实例中测试了width / height / borderwidth，它可以工作，但我不确定为什么它在这里不起作用。
