Detailed Description

The QSensorGesture class represents one or more sensor gesture recognizers.

In addition to the QSensorGesture::detected() signal, Sensor Gesture Recognizers can have their own specific signals, and may be discovered through QSensorGesture::gestureSignals().

Note that QSensorGesture uses a custom meta-object in order to provide recognizer-specific signals. This means it is not possible to sub-class QSensorGesture and use Q_OBJECT. Also qobject_cast<QSensorGesture*>(ptr) will not work.

You may use QSensorGestureManager to obtain the systems known sensor gesture ids.

See also QSensorGestureRecognizer and QSensorGestureManager.

Member Function Documentation

QSensorGesture::QSensorGesture(const QStringList &ids, QObject *parent = Q_NULLPTR)

Constructs the sensor gesture, and initializes the ids list of recognizers, with parent parent


Destroy the QSensorGesture

[signal] void QSensorGesture::detected(QString gestureId)

Signals when the gestureId gesture has been recognized.

QStringList QSensorGesture::gestureSignals() const

Returns all the possible gestures signals that may be emitted.

QStringList QSensorGesture::invalidIds() const

Returns the gesture recognizer ids that were not found.

bool QSensorGesture::isActive()

Returns whether this gesture is active or not.

void QSensorGesture::startDetection()

Starts the gesture detection routines in the recognizer.

void QSensorGesture::stopDetection()

Stops the gesture detection routines.

QStringList QSensorGesture::validIds() const

Returns the gesture recognizer ids that were found.
