This interface will pop up when the user sign-in is successful. This interface has a menu bar and a text file. Design and develop your own dashboard as an improvement.

Development

This is the code of the main interface defined in a method called main_screen. Also, this is the sign-in interface. In the end, run command of the main_screen method.

This is the code of the sign-up interface defined in a method called signup_screen. This interface will pop up when click the create a new account. Check the last button code in the main_screen method, signup_screen method is calling as the command of the button.

This is the code of the sign-up button. Check the sign-up button of the sigup_screen method, signup_action method is set as the command. In this method write/ append users' text file each time when a new user is adding and giving a success message.

This is the structure of user's text file. All users are saved in a string list.
I build this structure for easy access but you can build your own too.

This is the code of the sign-in button. Check the sign-in button of the main_screen method, signin_action is set as the command. In this method, read users' text files and check given entries are correct, and respond.


This is the design of the dashboard interface. Defined in a method called dashboard_screen. This interface has a menu bar and text frame.
