所以下面的代码是我的实际代码的缩写版本。我在获取一个小部件出现在一个放置在一个Frame中的Frame中时遇到问题。将小部件放入框架内的框架时出错。 Tkinter - Python3
因此，基本上下面的代码是一个登录菜单，其中当单击一个按钮时，该框架将更改为另一个框架。在这种情况下，login_frame到overview_frame。在overview_frame内我有另一个框架titleFrame，这个框架放在overview_frame上。
现在问题发生在我想将小部件放入titleFrame这个实例中titleLabel与.grid()放置方法。
我已经完成了这个与我创建的其他tkinter应用程序，我一直试图把这个好几个小时现在，而不是得出结论。这是我不断收到错误：
Traceback (most recent call last):
File "C:\Users\nasto\Documents\Company\rfr.py", line 67, in <module>
app = frame_store()
File "C:\Users\nasto\Documents\Company\rfr.py", line 16, in __init__
frame = n_frame(parent=container, controller=self)
File "C:\Users\nasto\Documents\Company\rfr.py", line 57, in __init__
titleLabel = tk.Label(titleFrame, text='TITLE').grid(row=0,column=0, sticky='nsew', padx=2, pady=2)

+ self._options(cnf, kw))
_tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack
现在这个代码，我所做的其他应用程序之间的唯一区别是frame_store类。其中有一行代码使用.Pack()但是，当删除此代码时，login_frame和titleFrame不显示，并且小部件将直接转到overview_frame。我将如何摆脱.Pack()，同时确保所有框架仍应可见，或将titleLabel放在titleFrame上，同时使用.grid() 我个人认为它可能与titleFrame连接的内容有关，例如// self但一边搞乱了我一直没有得到有效的结果。
