Sensor Gestures C++ 概述

使用 QtSensorGestures

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

使用 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 插件 .

主类

构成 QtSensorGestures API 的首要类：

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
