You can easily get text with QLineEdit.text() method. Or same way set text with QLineEdit.setText() method

If you want to connect it to QTextEdit You can connect it with .textChanged signal which is emited from QTextEdit everytime text changes.

The same way how you use .clicked signal you can use this one as:

QTextEdit.textChanged.connect(your_method_to_put_text_somewhere_else)
