Im getting an error running self.app.show_screen('login') in my homescreen class but it works fine in the loginscreen class and my app.
any idea why I'm getting this error

AttributeError: '_tkinter.tkapp' object has no attribute 'pages'
I'm not sure what is causing AttributeError: '_tkinter.tkapp' object has no attribute 'pages' when calling it from homescreen class but not from anywhere else
CodePudding user response：
The error is on this line:
poster = ttk.Button(self.poster_frame, image=self.photo, command=self.show_title())
You should leave the parenthesis:
poster = ttk.Button(self.poster_frame, image=self.photo, command=self.show_title)
Otherwise show_title will be called on initialization of Homescreen which occurs before MyApp.pages has been declared. Hence the error.
