Member Function Documentation
QCameraViewfinderSettingsControl::QCameraViewfinderSettingsControl(QObject * parent = 0) [protected]
Constructs a camera viewfinder control object with parent.
QCameraViewfinderSettingsControl::~QCameraViewfinderSettingsControl()
Destroys the camera viewfinder control object.
bool QCameraViewfinderSettingsControl::isViewfinderParameterSupported(ViewfinderParameter parameter) const [pure virtual]
void QCameraViewfinderSettingsControl::setViewfinderParameter(ViewfinderParameter parameter, const QVariant & value) [pure virtual]
Set the prefferred value of viewfinder 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 camara configuration is usually preferred.
See also viewfinderParameter().
QVariant QCameraViewfinderSettingsControl::viewfinderParameter(ViewfinderParameter parameter) const [pure virtual]
Returns the value of viewfinder parameter.
See also setViewfinderParameter().
