Detailed Description
Sensor Gesture plugins register their recognizers using the registerSensorGestureRecognizer() function.
// Create a QSensorGestureManager QSensorGestureManager gestureManager; // Get a list of known recognizers QStringList recognizersList = gestureManager.gestureIds(); // Create a QSensorGeture object for each of those gesture recognizers QSensorGesture *gesture = new QSensorGesture( gestureManager.gestureIds(), this); // Connect the known signals up. connect(gesture, SIGNAL(detected(QString)), this, SLOT(gestureDetected(QString)));
Member Function Documentation
QSensorGestureManager::QSensorGestureManager(QObject *parent = Q_NULLPTR)
Constructs the QSensorGestureManager as a child of parent
[signal]
void QSensorGestureManager::newSensorGestureAvailable()
Signals when a new sensor gesture becomes available for use.
[virtual]
QSensorGestureManager::~QSensorGestureManager()
Destroy the QSensorGestureManager
QStringList QSensorGestureManager::gestureIds() const
Returns the list of the currently registered gestures. Includes all the standard built-ins as well as available plugins.
QStringList QSensorGestureManager::recognizerSignals(const QString &gestureId) const
Returns the list of all the gesture signals for the registered gestureId gesture recognizer id.
bool QSensorGestureManager::registerSensorGestureRecognizer(QSensorGestureRecognizer *recognizer)
Registers the sensor recognizer recognizer for use. QSensorGestureManager retains ownership of the recognizer object. Returns true unless the gesture has already been registered, in which case the object is deleted.
[static]
QSensorGestureRecognizer *QSensorGestureManager::sensorGestureRecognizer(const QString &id)
Returns the sensor gesture object for the recognizer id.
