该类在 Qt 5.1 引入。

Sensor Gesture plugins register their recognizers using the registerSensorGestureRecognizer () 函数。
// 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)));
Constructs the QSensorGestureManager as a child of parent

void
QSensorGestureManager::
newSensorGestureAvailable
()
Signals when a new sensor gesture becomes available for use.
[虚拟]
QSensorGestureManager::
~QSensorGestureManager
()
Destroy the QSensorGestureManager
Returns the list of the currently registered gestures. Includes all the standard built-ins as well as available plugins.
Returns the list of all the gesture signals for the registered gestureId gesture recognizer id.
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.

*QSensorGestureManager::
sensorGestureRecognizer
(const
QString
&
id
)
Returns the sensor gesture object for the recognizer id .
