QMediaControl¶
- PyQt5.QtMultimedia.QMediaControl
Inherits from QObject.
Description¶
The QMediaControl class provides a base interface for media service controls.
Media controls provide an interface to individual features provided by a media service. Most services implement a principal control which exposes the core functionality of the service and a number of optional controls which expose any additional functionality.
A pointer to a control implemented by a media service can be obtained using the requestControl() member of QMediaService. If the service doesn’t implement a control it will instead return a null pointer.
# QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
# mediaService->requestControl("org.qt-project.qt.mediaplayercontrol/5.0"));
Alternatively if the IId of the control has been declared using Q_MEDIA_DECLARE_CONTROL the template version of requestControl() can be used to request the service without explicitly passing the IId or using .
# QMediaPlayerControl *control = mediaService->requestControl<QMediaPlayerControl *>();
Most application code will not interface directly with a media service’s controls, instead the QMediaObject which owns the service acts as an intermediary between one or more controls and the application.
