tkinter Attribute error - Object has no attribute. I don't understand why it can't find the attribute of this object
I am creating a rouge-like text based adventure game in python using tkinter and I am trying to set up the GUI. I want the menu bar to appear after I enter the main game screen (so after the player clicks 'start game'). For some reason python can't find the menubar that I have defined when I call the function for it and I'm can't understand why.
I have been trying different methods and doing research on other forums for a few days now but I have yet to find an answer. I have tried: - Creating a function - trying to call it the variable from another class - renaming the object - checked the indentation - As far as I can see, it is fine
I have also tried creating the menubar normally and having it load when the program runs. (i.e. not in a function but in the 'init' part of the class.) This works but I want the menu bar to appear later and not at the start.

This is my first post on stackoverflow so I apologise if any of my formatting is a bit off, especially the code that I have shown. I can't seem to get it to highlight the python syntax properly.
I hope that someone can help me. Thank you! >.<

It is because you call controller.CreateMenu() when creating GameMenu() and in this moment the self.menuBar used in controller.CreateMenu() does not exist as self.menuBar is created after GameMenu().
Try moving self.menuBar = tkMenu(self) in __init__(...) of class FireofStromwarld somewhere before the statement self.frames[1] = GameMenu(parent = frmContainer, controller = self).
