I have a code which open a main frame window with 2 buttons and a counter. If press Open Msg it show up a message and if i choose yes i open a new frame. If i press Open Page ZS it opens new frame also. My issue is that when i try to open that new frame from inside the function that do counting i get "NameError: global name 'controller' is not defined". Thank you in advance
我有一个代码打开一个主框架窗口,有2个按钮和一个计数器。如果按下打开消息它会显示一条消息,如果我选择是,则打开一个新帧。如果我按下Open Page ZS,它也会打开新的框架。我的问题是,当我尝试从计数函数内部打开新框架时,我得到“NameError:全局名称'控制器'未定义”。先感谢您

You're trying to use controller without defining it.
您正在尝试使用控制器而不定义它。
controller.show_frame(PageZS)
I would suggest adding
我建议补充一下
self.controller = controller
Under the init function and use
在init函数下使用
self.controller.show_frame(...)
