|
50 \brief The QVideoWindowControl class provides a media control for rendering video to a window. |
|
51 |
|
52 |
|
53 The winId() property QVideoWindowControl allows a platform specific window |
|
54 ID to be set as the video render target of a QMediaService. The |
|
55 displayRect() property is used to set the region of the window the video |
|
56 should be rendered to, and the aspectRatioMode() property indicates how the |
|
57 video should be scaled to fit the displayRect(). |
|
58 |
|
59 \code |
|
60 QVideoWindowControl *windowControl = mediaService->requestControl<QVideoWindowControl *>(); |
|
61 windowControl->setWinId(widget->winId()); |
|
62 windowControl->setDisplayRect(widget->rect()); |
|
63 windowControl->setAspectRatioMode(Qt::KeepAspectRatio); |
|
64 \endcode |
|
65 |
|
66 QVideoWindowControl is one of number of possible video output controls. |
|
67 |
|
68 The interface name of QVideoWindowControl is \c com.nokia.Qt.QVideoWindowControl/1.0 as |
|
69 defined in QVideoWindowControl_iid. |
