详细描述

The QTapSensor class is a convenience wrapper around QSensor.

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.

参见 QTapReading.

属性

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().

访问函数:

bool returnDoubleTapEvents() const
void setReturnDoubleTapEvents(bool returnDoubleTapEvents)

Notifier signal:

void returnDoubleTapEventsChanged(bool returnDoubleTapEvents)

成员函数

QTapSensor::QTapSensor(QObject *parent = Q_NULLPTR)

Construct the sensor as a child of parent.

[virtual] QTapSensor::~QTapSensor()

Destroy the sensor. Stops the sensor if it has not already been stopped.

QTapReading *QTapSensor::reading() const

Returns the reading class for this sensor.

参见 QSensor::reading().
