So i think this is possible but I'm not sure...
Im creating a login system for my program, the main screen is a tinter GUI root window, when this is created it is then .withdraw() and the top level login window is opened (this is stored in another module in a class). When the username and password are correct in the login top level window i want to .deiconify() the root window from within a method of the login window class. Is this possible and if so how....
Sorry i haven't got the code with me so can't upload any right now
Thank You!
Sure it's possible.  Just call root.deiconify().  You can either pass root as a parameter to the login window, or make it a global variable.
