Code:

---

QXmlInputSource *xmlSrc=new QXmlInputSource(reply);
    QXmlReader *reader;
      bool ok = reader->parse(xmlSrc);
    if(ok){
        QMessageBox::about(this,"Xml","Xml is parsed");
    }else{
        QMessageBox::about(this,"Error","Unable to parse");
    }

It shows following error while it is running

Code:

---

QWaitCondition: Destroyed while threads are still waiting

If anyone knows please help me...

Not sure if this is any way related to your problem but it seems you are calling parse() on a pointer that is never initialized:

Code:

---

QXmlReader *reader;
bool ok = reader->parse(xmlSrc);  // !!!!

My guess is that this causes your program to crash, and the QWaitCondition being destroyed is a side-effect of that.
