QtSensorGestures Plugins

Overview

The steps to creating a sensor gesture plugin are as follows:

• Sub-class from QSensorGesturePluginInterface
• Sub-class from QSensorGestureRecognizer and implement gesture recognizer logic using QtSensors.
• Create an instance of that recognizer in the derived QSensorGesturePluginInterface class, and call QSensorGestureManager::registerSensorGestureRecognizer(sRec); in your registerRecognizers() function. QSensorGestureManager will retain ownership of the recognizer object.

  This is the class in which the gesture recognizer system should be implemented from.

 MySensorGestureRecognizer::MySensorGestureRecognizer(QObject *parent)
     : QSensorGestureRecognizer(parent)
 {
 }

 MySensorGestureRecognizer::~MySensorGestureRecognizer()
 {
 }

 bool MySensorGestureRecognizer::start()
 {
     Q_EMIT mySignal();
     return true;
 }

 bool MySensorGestureRecognizer::stop()
 {
     return true;
 }

 bool MySensorGestureRecognizer::isActive()
 {
     return true;
 }

 void  MySensorGestureRecognizer::create()
 {
 }

 QString MySensorGestureRecognizer::id() const
 {
     return QString("QtSensors.mygestures");
 }

 MySensorGesturePlugin::MySensorGesturePlugin(){}
 MySensorGesturePlugin::~MySensorGesturePlugin(){}

 QList <QSensorGestureRecognizer *>  MySensorGesturePlugin::createRecognizers()
 {
     QList <QSensorGestureRecognizer *>  recognizers;
     MySensorGestureRecognizer *recognizer = new MySensorGestureRecognizer(this);
     recognizers.append(recognizer);

     return recognizers;
 }

 QStringList MySensorGesturePlugin::supportedIds() const
 {
        return QStringList() << "QtSensors.mygestures";
 }
