You can easily get text with QLineEdit.text()method.
Or same way set text with QLineEdit.setText()method
您可以使用QLineEdit.text()方法轻松获取文本。或以同样的方式使用QLineEdit.setText()方法设置文本
If you want to connect it to QTextEditYou can connect it with .textChangedsignal which is emited from QTextEdit everytime text changes.
如果你想将它连接到QTextEdit你可以将它与.textChanged每次文本更改时从 QTextEdit 发出的信号连接起来。
The same way how you use .clickedsignal you can use this one as:
与使用.clicked信号的方式相同，您可以将其用作：
QTextEdit.textChanged.connect(your_method_to_put_text_somewhere_else)
