Detailed Description
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
[signal] void QSensorGesture::detected(QString)
Signals when the gestureId gesture has been recognized.
[virtual] QSensorGesture::~QSensorGesture()
Destroy the QSensorGesture
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.
