Re-answering, with the additional data provided at the comment:

You can connect all buttons to the same slot and then use the sender() method to identify who is triggering the signal:

void MyClass::button_clicked() {
    QAbstractButton* button = qobject_cast<QAbstractButton*>(sender());
    if ( !button ) {
        return; // not called from a button.
    }
    button->setText("Clicked");
}
