在Python中，我想回到主窗口的后退按钮。

Question

我的代码有一些问题。我想做一个后退按钮，但当我显示窗口时出现了错误。我的目标是做一个目录，用户可以在其中按下一些按钮，并与产品互动。但是当你按下按钮的时候，这个错误就出来了。

Exception in Tkinter callback
Traceback (most recent call last):
  File "/Users/williamgranizo/.conda/envs/untitled/lib/python3.7/tkinter/__init__.py", line 1705, in __call__
    return self.func(*args)
  File "/Users/williamgranizo/.conda/envs/untitled/lib/python3.7/site-packages/tkmacosx/basewidget.py", line 255, in cmd
    self.unbind_class('button_command', '<ButtonRelease-1>')
  File "/Users/williamgranizo/.conda/envs/untitled/lib/python3.7/site-packages/tkmacosx/basewidget.py", line 496, in unbind_class
    bindtags = list(self.bindtags())
  File "/Users/williamgranizo/.conda/envs/untitled/lib/python3.7/tkinter/__init__.py", line 1192, in bindtags
    self.tk.call('bindtags', self._w))
_tkinter.TclError: bad window path name ".!toplevel2.!button6"

我不知道主要的问题是什么，但主窗口似乎仍然可以工作。我的代码是

def m1():

ventana.withdraw
modelo_1 = Toplevel()
modelo_1.title("Rose&Frites Hoodie con Gorra")
modelo_1.geometry("700x700")
modelo_1.configure(bg='black')

              command= modelo_1.destroy).place(x=0, y=0)

Answer 1

错误 _tkinter.TclError: bad window path name 当您使用 tkmacosx 销毁任何窗口时触发。Button. 这个问题已经在最新的更新中得到了解决。tkmacosx (0.1.3).

用pip更新包，应该可以解决这个错误。

pip install tkmacosx --upgrade

或

pip install tkmacosx==0.1.3
