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 \l {QMediaService::requestControl()} member of QMediaService. If the + service doesn't implement a control it will instead return a null pointer. + + \snippet doc/src/snippets/multimedia-snippets/media.cpp Request control + + Alternatively if the IId of the control has been declared using + Q_MEDIA_DECLARE_CONTROL the template version of + QMediaService::requestControl() can be used to request the service without + explicitly passing the IId or using qobject_cast(). + + \snippet doc/src/snippets/multimedia-snippets/media.cpp Request control templated + + 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. + + \sa QMediaService, QMediaObject +*/ + +/*! + \macro Q_MEDIA_DECLARE_CONTROL(Class, IId) + \relates QMediaControl + + The Q_MEDIA_DECLARE_CONTROL macro declares an \a IId for a \a Class that + inherits from QMediaControl. + + Declaring an IId for a QMediaControl allows an instance of that control to + be requested from QMediaService::requestControl() without explicitly + passing the IId. + + \snippet doc/src/snippets/multimedia-snippets/media.cpp Request control templated + + \sa QMediaService::requestControl() +*/ + +/*! + Destroys a media control. +*/ + +QMediaControl::~QMediaControl() +{ + delete d_ptr; +} + +/*! + Constructs a media control with the given \a parent. + \since 1.0 +*/ + +QMediaControl::QMediaControl(QObject *parent) + : QObject(parent) + , d_ptr(new QMediaControlPrivate) +{ + d_ptr->q_ptr = this; +} + +/*! + \internal + \since 1.0 +*/ + +QMediaControl::QMediaControl(QMediaControlPrivate &dd, QObject *parent) + : QObject(parent) + , d_ptr(&dd) + +{ + d_ptr->q_ptr = this; +} + +#include "moc_qmediacontrol.cpp" +QT_END_NAMESPACE + |
