I have been resisting posting this question but have finally decided to put my pride in my pocket and admit that I cannot get the menu creation section of my program to work. I still do not seem to have been able to fully grasp the workings of Classes. The program that I have written is basically a Cashbook keeping track of cash receipts and expenses and analysing them to various accounts. This all works fine. Then I also added a second window to add analysis items. This also works fine. However, finally I have tried to add a menu but cannot get it to work. When I run the program it does not throw out any errors but no menu ('File/Exit') appears. Can someone please look at the following (Menu_ex) code and tell me where it fails? Thank you in anticipation.

Short answer is that you weren't actually creating an instance of your Menu class so it would never be displayed
Below code displays the menu and fixes the exit button
