回答1:

Like this?

QString text = someLabel->text();

回答2:

Here is the documentation. QLabel.text()

EDIT:

QString text = theLabel.text();
//or with pointer
QString text = theLabel->text();

回答3:

have you tried :

QString s = YourQLabel->text();

This should work, I guess.

// Thelepaty mode on

You need to use editor widgets, for example QLineEdit or QTextEdit. You may customize it via QSS to look like a QLabel.

P.S. try to improve your English. It is hard to understand, what you are asking.
