Detailed Description

The QCameraViewfinderSettingsControl class provides an abstract class for controlling camera viewfinder parameters. New backends should implement QCameraViewfinderSettingsControl2 rather than use this class. Application developers should request this control only if QCameraViewfinderSettingsControl2 is not available.

The interface name of QCameraViewfinderSettingsControl is "com.copperspice.CS.cameraViewfinderSettingsControl/1.0" as defined in QCameraViewfinderSettingsControl_iid.

See also: QMediaService::requestControl(), QCameraViewfinderSettingsControl2, QCamera

Constructor & Destructor Documentation

QCameraViewfinderSettingsControl::~QCameraViewfinderSettingsControl ( )

Destroys the camera viewfinder control object.

QCameraViewfinderSettingsControl::QCameraViewfinderSettingsControl ( QObject * parent = nullptr )

explicitprotected

Constructs a camera viewfinder control object with parent.

Method Documentation

bool QCameraViewfinderSettingsControl::isViewfinderParameterSupported ( ViewfinderParameter parameter ) const

pure virtual

Returns true if configuration of the viewfinder parameter is supported by camera backend.

void QCameraViewfinderSettingsControl::setViewfinderParameter	(	ViewfinderParameter	parameter,
		const QVariant &	value
	)

pure virtual

Sets the preferred value of viewfinder to parameter.

Calling this while the camera is active may result in the camera being stopped and reloaded. If video recording is in progress, this call may be ignored. If an unsupported parameter is specified the camera may fail to load, or the setting may be ignored.

Viewfinder parameters may also depend on other camera settings, especially in video capture mode. If camera configuration conflicts with viewfinder settings, the camera configuration is usually preferred.

QVariant QCameraViewfinderSettingsControl::viewfinderParameter ( ViewfinderParameter parameter ) const

pure virtual

Returns the value of viewfinder parameter.

See also: setViewfinderParameter()
