This specific window has 2 QLineEdits: one called "User" and the other called "Password". Below them there is a keyboard created with many QPushButtons. Now, I have to tell the method connected to those buttons to print the respective letter or number in the selected QLineEdit and I'm having a hard time getting the signal for which QLineEdit is selected at the moment.
How do I do I get that signal? The application starts with "User" focused: self.User.setFocus()
Thank you.
