Public Functions
| QTapSensor(QObject *parent = Q_NULLPTR) | |

Detailed Description
The only behavioural difference is that this class sets the type properly.
This class also features a reading() function that returns a QTapReading instead of a QSensorReading.
For details about how the sensor works, see QTapReading.

Property Documentation
returnDoubleTapEvents : bool
This property holds a value indicating if double tap events should be reported.
Set to true (the default) to have the sensor report only on double tap events. Set to false to have the sensor report only on individual tap events.
It is not possible to have the sensor report both single and double tap events. If both are needed the app should create 2 sensor objects.
The property must be set before calling start().
Access functions:
| bool | returnDoubleTapEvents() const |
| void | setReturnDoubleTapEvents(bool returnDoubleTapEvents) |
Notifier signal:
| void | returnDoubleTapEventsChanged(bool returnDoubleTapEvents) |
