How to read the content of DNS record?

I have multiples DNS record (MX, CNAME , TXT) and I would like to read the TXT record content.

Is it possible?
Is there any example?

Thanks.

Could you help me, please?

The lookup() function never emit finished() or error(), I tried using this code:

Code:

---

m_dns = new QDnsLookup(this);
connect(m_dns, SIGNAL(finished()), this, SLOT(onHandle()));
 
m_dns->setType(QDnsLookup::TXT);
m_dns->setName("uol.com.br");
m_dns->lookup();
 
 
void Update::onHandle()
{
  if (m_dns->error() != QDnsLookup::NoError)
      qDebug() << m_dns->error() << m_dns->errorString();
 
  foreach (const QDnsServiceRecord &record, m_dns->serviceRecords()) {
    qDebug() << "Name:   " << record.name() << "Target: " << record.target();
  }
 
  emit handled();
}

Thanks any help,

QDnsLookup appears to use a thread pool to perform its DNS lookup requests. Do you have an event loop running at the time you do the m_dns->lookup()?

Edit: Also, you said you're looking for TXT records, so your OnHandle slot should be looking at m_dns->textRecords(), not m_dns->serviceRecords(), correct?

Thank you very much! It is working with m_dns->textRecords()

Glad its working for you, but I thought your issue was that the finished() signal was never fired? What did you change to get that working?
