[Interest] QDirIterator as Variable in class

[Adrian Stern]

Hello

I want to iterate trough a directory one step at a time. Driven by signals.
So after each signal I want to do another step.

I have createt the following class in which I try to create a variable of  the type of QDirIterator. This however fails with the message "no matching function for call to 0QDirIterator::QDirIterator()' in the constructor.

If I comment out the mediaItr variable declaration, it works without error. So what is it I'm doing wrong? A assume its something due to my .NET background so I don't see the whole cpp scope yet.

Class.h:
class MediaBase : public QObject
{
  Q_OBJECT

  QObject *player;
  QDir mediaDir;
  QDirIterator mediaItr;

public:
  explicit MediaBase(QObject *parent = 0);
  void setPlayer (QObject *player = 0);
  void setMediaDir (QString path);

private:
  QVariant getNext();

signals:

public slots:
  void movieStopped() {
    if (player!=NULL) player->setProperty("thesource", getNext());
  }
};

Class.cpp:
MediaBase::MediaBase(QObject *parent) : QObject(parent) {
  QDirIterator mediaItr();
}

void MediaBase::setPlayer(QObject *player) {
  this->player = player;
}

void MediaBase::setMediaDir (QString path) {
  mediaDir = QDir(path);
  if (mediaDir.exists()){
    //this->mediaItr = QDirIterator(mediaDir);
  }
  else qDebug() << "could not load mediaDir" << endl;
}

QVariant MediaBase::getNext(){
  return QVariant();
}
