    I have additional problem with QQuickView(),
    namely I couldn't set transparency for it.
    If I set ->setColor(QColor(0,0,0,0)) it's starting to be black.

    setColor(Qt::transprarent) also dosn't help.

    Anyone know smth about ?

      Hi,

      In the future, please start a new thread for new questions.

      Anyway, you need to call QQuickWindow::setDefaultAlphaBuffer(true) before you create your QQuickView. See http://qt-project.org/doc/qt-5/qquickwindow.html#setDefaultAlphaBuffer

          code:

          @ QQuickWindow::setDefaultAlphaBuffer(true);
          this->viewQML = new QQuickView();
          this->viewQML->setFlags(Qt::FramelessWindowHint);
          this->viewQML->setColor(QColor(0, 0, 0, 0));
          this->containerQML = QWidget::createWindowContainer( this->viewQML, this );
          this->containerQML->adjustSize();
          this->containerQML->setFocusPolicy( Qt::TabFocus );
          this->containerQML->setMinimumSize( 75, 75 );

            I would expect to use this in your main before any qml file is loaded.

            Hope it helps
