The QSensorGestureRecognizer class is the base class for a sensor gesture recognizer.
QSensorGesture recognizer developers should sub-class this to implement their own recognizer.
All sensor gesture recognizers have a detected(QString) signal. Implementors can use this and send recognizer specific gestures, such as detected("shake_left") or implement custom signals such as shakeLeft().
These custom signals will be available in the QSensorGesture object at runtime.
See also QSensorGestureRecognizer::gestureSignals().
Constructs the QSensorGestureRecognizer with parent as parent.
Destroy the QSensorGestureRecognizer
Called by QSensorGesture object constructor to create the recognizers backend.
Implementors would use this to instantiate QSensors and connect signals.
Calls QSensorGestureRecognizer::create() if the recognizer is valid.
Signals when the gestureId gesture has been recognized.
Returns a list of signals that this recognizer supports.
Note that all signals declared will be exported to the QSensorGesture object. If you need to use signals that are not exported, you should use a private class to do so.
Returns the identifier for this recognizer.
Returns true if this recognizer is active, otherwise false.
Called by QSensorGesture::startDetection() to start this recognizer. Implementors should start the sensors. Returns true if the operation is successful.
Calls QSensorGestureRecognizer::start() if the recognizer isn't already initialized. This is called by the QSensorGesture object, so please use that instead.
See also QSensorGesture::startDetection().
Called by QSensorGesture::stopDetection() to stop this recognizer. Returns true if the call succeeds, otherwise false.
Implementors should stop the sensors.
Calls QSensorGestureRecognizer::stop() if no other clients are using it. This is called by the QSensorGesture object, so please use that instead.
