Detailed Description
The QVideoDeviceSelectorControl class provides an video device selector media control.
The QVideoDeviceSelectorControl class provides descriptions of the video devices available on a system and allows one to be selected as the endpoint of a media service.
The interface name of QVideoDeviceSelectorControl is org.qt-project.qt.videodeviceselectorcontrol/5.0 as defined in QVideoDeviceSelectorControl_iid.
Member Function Documentation
[protected] QVideoDeviceSelectorControl::QVideoDeviceSelectorControl(QObject *parent = nullptr)
Constructs a video device selector control with the given parent.
[virtual] QVideoDeviceSelectorControl::~QVideoDeviceSelectorControl()
Destroys a video device selector control.
[pure virtual] int QVideoDeviceSelectorControl::defaultDevice() const
[pure virtual] int QVideoDeviceSelectorControl::deviceCount() const
[pure virtual] QString QVideoDeviceSelectorControl::deviceDescription(int index) const
[pure virtual] QString QVideoDeviceSelectorControl::deviceName(int index) const
[signal] void QVideoDeviceSelectorControl::devicesChanged()
[pure virtual] int QVideoDeviceSelectorControl::selectedDevice() const
See also setSelectedDevice().
[signal] void QVideoDeviceSelectorControl::selectedDeviceChanged(int index)
Note: Signal selectedDeviceChanged is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:
connect(videoDeviceSelectorControl, QOverload<int>::of(&QVideoDeviceSelectorControl::selectedDeviceChanged), [=](int index){ /* ... */ });
[signal] void QVideoDeviceSelectorControl::selectedDeviceChanged(const QString &name)
Note: Signal selectedDeviceChanged is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:
connect(videoDeviceSelectorControl, QOverload<const QString &>::of(&QVideoDeviceSelectorControl::selectedDeviceChanged), [=](const QString &name){ /* ... */ });
[pure virtual slot] void QVideoDeviceSelectorControl::setSelectedDevice(int index)
See also selectedDevice().
