QThread to send large queries to the database

Question

Hi!

I have created this class that inherits from QThread for send data to the database server, what do you think about it? Could be impreved?

Thanks

#ifndef QUERYTHREAD_H
#define QUERYTHREAD_H

#include 

class QSqlQuery;

class QueryThread : public QThread {
    public slots:
     bool exec(QSqlQuery *query, Priority priority=InheritPriority);
    protected:
     virtual void run();
    private:
     bool m_hasError;
     QSqlQuery *q;
};

#endif // QUERYTHREAD_H

#include "querythread.h"

#include 
#include 

bool QueryThread::exec(QSqlQuery *query, Priority priority)
{
    q=query;
    start(priority);
    while(isRunning()) qApp->processEvents();
    return m_hasError;
}

void QueryThread::run()
{ m_hasError=q->exec(); }
