How to pass text from one window to another in qt using the signals and slots mechanism?

Question

Qt

The user enters his name in QLineEdit and on pressing the button a second window opens, where the user's greeting and his name are displayed in the label. How to implement this using the signals and slots mechanism?

Answer 1

Why is there a signal/slot mechanism here? Just pass the value from QLineEdit::Text as a parameter to the second window's constructor.
