QtSensors Sensor Gestures C++ Overview

With the Sensor Gestures classes, you are able to easily utilize device gesturing using sensors, such as the accelerometer and proximity.

A list of currently supported sensor gestures and their descriptions can be found here: Qt Sensor Gestures

Using QtSensorGestures is easy. There are two main classes you will need to use:

  • QSensorGestureManager: can be used for determining which sensor gestures are available.
  • QSensorGesture : for connecting the sensor gesture signals.
// 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)));

More information about the sensor gesture recognizers can be found in QtSensorGestures Plugins.

The primary classes that make up the QtSensorGestures API:

QSensorGesture Represents one or more sensor gesture recognizers
QSensorGestureManager Manages sensor gestures, registers and creates sensor gesture plugins

The primary classes that make up the QtSensorGesturesRecognizers API:

QSensorGesturePluginInterface The pure virtual interface to sensor gesture plugins
QSensorGestureRecognizer The base class for a sensor gesture recognizer
