Qt. How to get a pointer to the widget that emitted the signal in the slot?

Question

Qt

There can be any number of buttons, and they are created dynamically. Naturally, they connect to the same slot. How can I get a pointer to the QPushButton that emitted the signal? Or, if not, how can this problem be solved differently?

Answer 1

QPushButton *button = qobject_cast<QPushButton*>(sender());

Answer 2

QObject* obj = sender();
