as defined in QVideoDeviceSelectorControl_iid.
Member Function Documentation
[protected]
QVideoDeviceSelectorControl::QVideoDeviceSelectorControl(QObject *parent = Q_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
Returns the index of the default video device.
[pure virtual]
int QVideoDeviceSelectorControl::deviceCount() const
Returns the number of available video devices;
[pure virtual]
QString QVideoDeviceSelectorControl::deviceDescription(int index) const
Returns a description of the video device at index.
[pure virtual]
QString QVideoDeviceSelectorControl::deviceName(int index) const
Returns the name of the video device at index.
[signal]
void QVideoDeviceSelectorControl::devicesChanged()
Signals that the list of available video devices has changed.
[pure virtual]
int QVideoDeviceSelectorControl::selectedDevice() const
Returns the index of the selected video device.
See also setSelectedDevice().
[signal]
void QVideoDeviceSelectorControl::selectedDeviceChanged(int index)
Signals that the selected video device index has changed.
Note: Signal selectedDeviceChanged is overloaded in this class. To connect to this one using the function pointer syntax, you must specify the signal type in a static cast, as shown in this example:
connect(videoDeviceSelectorControl, static_cast<void(QVideoDeviceSelectorControl::*)(int)>(&QVideoDeviceSelectorControl::selectedDeviceChanged), [=](int index){ /* ... */ });
[signal]
void QVideoDeviceSelectorControl::selectedDeviceChanged(const QString &name)
Signals that the selected video device name has changed.
Note: Signal selectedDeviceChanged is overloaded in this class. To connect to this one using the function pointer syntax, you must specify the signal type in a static cast, as shown in this example:
connect(videoDeviceSelectorControl, static_cast<void(QVideoDeviceSelectorControl::*)(const QString &)>(&QVideoDeviceSelectorControl::selectedDeviceChanged), [=](const QString &name){ /* ... */ });
[pure virtual slot]
void QVideoDeviceSelectorControl::setSelectedDevice(int index)
Sets the selected video device index.
See also selectedDevice().
