qtScrollDial and QLCDNumber communication

[saman_artorious]

I have a problem here, I have 3 QtScrollDials inside X class. I edited the updateLabel slot of QtScrollDials class so when it updates the label it also sends a signal to X class, so that I can get its value and set my QLCDNumber accordingly.

void QtScrollDial::updateLabelValue()
{
    m_label->setText(QString::number(value()));
    emit updateDisplaySignal_valueChangedDahgan(value());
}

void QtScrollDial::updateLabelValue()
{
    m_label->setText(QString::number(value()));
    emit updateDisplaySignal_valueChangedDahgan(value());
}

The problem I have is that I have 3 dials, not one, for each of these dials I need to emit 3 different signals so that I can understand which dial sent the signal.
do have any idea how I can do that?
