QQuickWidget in Widgets Application

[makzak]

Hi,

i'm developing qt widgets application and I want to add QML object into UI. I'm using QuickWidget like this:

@QuickWidget::QuickWidget(QWidget *parent)
: QQuickWidget(parent)
{
setSource(QUrl(QStringLiteral("qrc:/test1.qml")));
}@

Then I promoted QWidget to QuickWidget. As I run the app, the widget is filled with "UI copy" (have no idea why..) and the QML area is filled with black color like this:

If I resize the application window, the UI changes and insted of black area the QML file is displayed, but also inside whole UI copy like this:

Could anyone help me solve this? I tested my code on simple app (only 1 QTabWidget with 2 tabs) an it works great. So the problem is not in non-working QML.

Thanks for any advice.

Ok,

I did some more investigation and find out the problem is caused with this line:

@player->setVideoOutput(videoWidget);@

In the previous tab "Camera" is only one QWidget named videoContainer.
Here is code I'm using to add video into this QWidget:

@ // init player
player = new QMediaPlayer;

// init playlist
playlist = new QMediaPlaylist(player);

// add video files from local disk
playlist->addMedia(QUrl::fromLocalFile("...."));
playlist->addMedia(QUrl::fromLocalFile("..."));

// playlist index
playlist->setCurrentIndex(1);

// play in loop
playlist->setPlaybackMode(QMediaPlaylist::Loop);
player->setPlaylist(playlist);

// ui video frame
QWidget *qw = ui->videoContainer;

// init video widget
videoWidget = new QVideoWidget(qw);

videoWidget->setMinimumSize(400,300);

// THIS CAUSES THE ERROR - assign output widget
player->setVideoOutput(videoWidget);@

Could this be a bug or am I using it wrong way?
Thanks for any help.
