A simple mDNS responder written in Qt

qMDNS is a library that allows your Qt applications to interact with a mDNS network group without the need of installing Bonjour or Avahi. qMDNS works on every operating system that supports the Qt networking module.

How to use qMDNS

qMDNS is a singleton class, you can call it anywhere from your application using:

#include <qMDNS.h>

Chat::Chat() {
   connect (qMDNS::getInstance(), &qMDNS::hostFound,
            this,                 &Chat::onHostFound);
            
   findBob();
}

void Chat::findBob() {        
    qMDNS::getInstance()->lookup ("bob-computer.local");
}

void Chat::onHostFound (const QHostInfo& info) {
    qDebug() << "Bob is at" << info.addresses().first();
}
