Detailed Description

The QCameraFocusControl class supplies control for focusing related camera parameters.

The interface name of QCameraFocusControl is "com.copperspice.CS.cameraFocusControl/1.0" as defined in QCameraFocusControl_iid.

Constructor & Destructor Documentation

QCameraFocusControl::~QCameraFocusControl ( )

Destruct the camera control object.

QCameraFocusControl::QCameraFocusControl ( QObject * parent = nullptr )

explicitprotected

Constructs a camera control object with parent.

Method Documentation

QPointF QCameraFocusControl::customFocusPoint ( ) const

pure virtual

Return the position of custom focus point, in relative frame coordinates: QPointF(0,0) points to the left top frame point, QPointF(0.5,0.5) points to the frame center.

Custom focus point is used only in FocusPointCustom focus mode.

See also: setCustomFocusPoint()

void QCameraFocusControl::customFocusPointChanged ( const QPointF & point )

signal

Signal is emitted when the custom focus point is changed.

See also: QCameraFocusControl::customFocusPoint(), QCameraFocusControl::setCustomFocusPoint()

QCameraFocus::FocusModes QCameraFocusControl::focusMode ( ) const

pure virtual

Returns the focus mode being used.

See also: setFocusMode()

void QCameraFocusControl::focusModeChanged ( QCameraFocus::FocusModes mode )

signal

Signal is emitted when the focus mode is changed, usually in result of QCameraFocusControl::setFocusMode call or capture mode changes.

See also: QCameraFocusControl::focusMode(), QCameraFocusControl::setFocusMode()

QCameraFocus::FocusPointMode QCameraFocusControl::focusPointMode ( ) const

pure virtual

Returns the camera focus point selection mode.

See also: setFocusPointMode()

void QCameraFocusControl::focusPointModeChanged ( QCameraFocus::FocusPointMode mode )

signal

Signal is emitted when the focus point mode is changed, usually in result of QCameraFocusControl::setFocusPointMode call or capture mode changes.

See also: QCameraFocusControl::focusPointMode(), QCameraFocusControl::setFocusPointMode()

QCameraFocusZoneList QCameraFocusControl::focusZones ( ) const

pure virtual

Returns the list of zones, the camera is using for focusing or focused on.

void QCameraFocusControl::focusZonesChanged ( )

signal

Signal is emitted when the set of zones, camera focused on is changed. Usually the zones list is changed when the camera is focused.

See also: QCameraFocusControl::focusZones()

bool QCameraFocusControl::isFocusModeSupported ( QCameraFocus::FocusModes mode ) const

pure virtual

Returns true if focus mode is supported.

bool QCameraFocusControl::isFocusPointModeSupported ( QCameraFocus::FocusPointMode mode ) const

pure virtual

Returns true if the camera focus point mode is supported.

void QCameraFocusControl::setCustomFocusPoint ( const QPointF & point )

pure virtual

Sets the custom focus point.

If camera supports fixed set of focus points, it should use the nearest supported focus point, and return the actual focus point with QCameraFocusControl::focusZones().

See also: QCameraFocusControl::customFocusPoint(), QCameraFocusControl::focusZones()

void QCameraFocusControl::setFocusMode ( QCameraFocus::FocusModes mode )

pure virtual

Set the focus mode to mode.

See also: focusMode()

void QCameraFocusControl::setFocusPointMode ( QCameraFocus::FocusPointMode mode )

pure virtual

Sets the camera focus point selection mode.

See also: focusPointMode()
