How to pass value from LineEdit form 1 to Label form 2, Qt?

Question

Qt

There is a form Form1 and Form2. When you press the OK button on Form2 after entering the line, LineEdit Form2 closes, and the value that was in LineEdit must be passed to Label Form2

Answer 1

Connect these things through slots and signals. The textChanged(QString) signal from QLineEdit needs to be bound to the setText(QString ) slot of the QLabel.
