When you reopen the application, the state of the text fields and buttons should be the same as before closing. How to do it?

Answer 1

Save the content\state of the necessary components in json\txt\prop\xml\etc when the program is closed and restore it when it is opened (the form is drawn, you read the state and fill in the required one).
