Question

I can implement SignalMapper saperately f

Answer 1

QSignalMapper can map a QObject and a integer. So you can map your non-standardButton with its role and create a slot that takes in parameter a role:

For example:

void Widget::initMap() {
     QPushButton* buttonReset = new QPushButton( "Reset" );
     signalMapper = new QSignalMapper(this);
     connect(buttonReset, SIGNAL(clicked()), signalMapper, SLOT(map()));
     signalMapper->setMapping(button, QDialogButtonBox::ResetRole);
     connect(signalMapper, SIGNAL(mapped(int)), this, SLOT(slot(int)));
}

void Widget::slot( int role) {
    if ( role == QDialogButtonBox::ResetRole ) {
        reset();
    } else if ( QDialogButtonBox::Apply ) {
        apply();
    }
}
