QCameraFocusControl::QCameraFocusControl(QObject * parent = 0) [protected]
Constructs a camera control object with parent.
QCameraFocusControl::~QCameraFocusControl()
Destruct the camera control object.
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() and 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() and 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() and 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() and 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().
