I am developing a GUI to manage my databases with Tkinter in Python 2.7. I have the main window where are the text boxes to fill in the data when I create a new record and on the other hand I have a toplevel window in which the user's data of the people are displayed, such as first name and user taken from the database , then what I'm asking is if 'is it possible to select a user and using a button to indicate that the main window is autollene with the data of the selected user?
