QVideoWidget stand alone. How to stop video when window closes?

Question

I have the following

QVideoWidget* vw = new QVideoWidget;
QMediaResource mr(QUrl::fromLocalFile(item->data(Qt::UserRole + FilepathRole).toString()));
QMediaContent mc(mr);
QMediaPlayer* player = new QMediaPlayer;
QObject::connect(vw,SIGNAL(destroyed(QObject*)),player,SLOT(stop()));
player->setMedia(mc);
player->setVideoOutput(vw);
QRect rect = QApplication::desktop()->availableGeometry();
int width = vids[vids.indexOf(item->data(Qt::UserRole + FilepathRole).toString())].width;
int height = vids[vids.indexOf(item->data(Qt::UserRole + FilepathRole).toString())].height;
int x = (rect.width() / 2) - (width / 2);
int y = (rect.height() / 2) - (height / 2);
vw->setGeometry(x,y,width,height);
vw->show();
player->play();

everything works except that when I close the window for the QVideoWidget that pops up the video keeps playing somewhere, or at least the sound does. I thought that connect line would do the trick but it does not. What is the correct way to stop playback when closing the QVideoWidget window?

Answer 1

The problem is most likely that the window is not destroyed when you close it, so stop does not actually get called. You can to set the Qt::WA_DeleteOnClose using the QWidget::setAttribute() to change the behaviour.

vw->setAttribute( Qt::WA_DeleteOnClose );
