Using QHttp with Qthread

[schroffi]

Hello,
i have a qt application where i have to download some files and pictures in the background while the appliction is going on. and the user should be informed when the upload is finished.

My idea is to open a new thread and in a loop start the http requests (witch is done by a own class - using the QHTTP). But the thread is not waiting, and the requests are not starting. How can i do this?

I subclass the qthread and use my class in the mainwindow

KurierDLThread* threadDl;
threadDl = new  KurierDLThread(this);
    if(threadDl->isRunning()) return;

    qDebug() << "start thread";
    threadDl->setValues(boolNach,boolGall,boolVideo,boolHoro,boolTv,strStorageDataPath);

    connect(threadDl,SIGNAL(signalAddLoading()),this, SLOT(slotAddLoadingDL()));
    connect(threadDl,SIGNAL(signalRemoveLoading()), this,SLOT(slotRemoveLoadingDL()));

    threadDl->start();

And here the SUbclass:
part of .h

class KurierDLThread : public QThread
{
    Q_OBJECT
public:
    KurierDLThread(QObject* parent = 0);
    void setValues(bool boolSNachrichten, bool boolSGallery, bool boolSVideo, bool boolSHoroskop, bool boolSTv,QString strPath);
    void saveAll();
protected:
    void run();
}

part of .cpp

void KurierDLThread::run()
{
    emit signalAddLoading();
    QObject qWaitObj(this->parent());
    qWaitAll = new QObject(this->parent());
    int intRes = kurDatabaseObj->deleteFolders(0,strStorageDataPath);
     if(boolStatusNachrichten)
     {
         saveNachrichten();
     }
     if(boolStatusTv)
     {
         saveTv();
     }
     if(boolStatusGallery)
     {
         qDebug() << "save gallerys";
         saveGallery();
     }
     if(boolStatusVideo)
     {
         qDebug() << "save video";
         saveVideo();
     }

     if(boolStatusHoroskop)
     {
         saveHoroskop(&qWaitObj);
     }
     emit signalRemoveLoading();
     deleteLater();
}

void KurierDLThread::saveHoroskop(QObject* qWaitObj)
{
    QSqlTableModel model;

    QString strFilter = "feedtype='";
    strFilter += "horoskop";
    strFilter += "'";
    qDebug() << "READ" << strFilter;
    model.setTable("feed_config");
    model.setFilter(strFilter);
    model.select();

    if( model.rowCount()> 0)
     {
         qDebug() << "horoskop read";

         QSqlRecord record = model.record(0);


         QString  strFilename = strStorageDataPath + "/horoskop.xml";
          qDebug() << "config file : " << strFilename;
          IqNetworkDataObject* iqDownloadObj = new IqNetworkDataObject(this->parent());
          qDebug() << "nw thread" << iqDownloadObj->thread();
         // iqDownloadObj->moveToThread(this->thread());
          qDebug() << "nw thread2 " << iqDownloadObj->thread();
          qDebug() << "this thread " << this->thread();
          connect(iqDownloadObj,SIGNAL(signalAddLoading()), this, SLOT(slotAddLoading()));
          connect(iqDownloadObj,SIGNAL(signalRemoveLoading()), this, SLOT(slotRemoveLoading()));
          iqDownloadObj->requestFile(record.value("feedurl").toString(),strFilename);
          iqDownloadObj->deleteLater();


     }

}

QHttp deprecated ... you should consider rewrite that code by using QNetwork api

[divanov]

Yes, QHttp is deprecated and QNetworkAccessManager is good enough to do it within one thread.
