\class QVideoWindowControl
\preliminary
\since 4.7
\ingroup multimedia-serv
\brief The QVideoWindowControl class provides a media control for rendering video to a window.
The winId() property QVideoWindowControl allows a platform specific
window ID to be set as the video render target of a QMediaService. The
displayRect() property is used to set the region of the window the
video should be rendered to, and the aspectRatioMode() property
indicates how the video should be scaled to fit the displayRect().
\code
QVideoWindowControl *windowControl = mediaService->control<QVideoWindowControl *>();
windowControl->setWinId(widget->winId());
windowControl->setDisplayRect(widget->rect());
windowControl->setAspectRatioMode(Qt::KeepAspectRatio);
\endcode
QVideoWindowControl is one of number of possible video output controls,
in order to receive video it must be made the active video output
control by setting the output property of QVideoOutputControl to \l {QVideoOutputControl::WindowOutput}{WindowOutput}.
Consequently any QMediaService that implements QVideoWindowControl must
also implement QVideoOutputControl.
\code
QVideoOutputControl *outputControl = mediaService->control<QVideoOutputControl *>();
outputControl->setOutput(QVideoOutputControl::WindowOutput);
\endcode
The interface name of QVideoWindowControl is \c com.nokia.Qt.QVideoWindowControl/1.0 as
defined in QVideoWindowControl_iid.
