詳細描述

This type provides notification when sensor gestures are triggered.

The following QML code creates a "shake" and "SecondCounter" SensorGesture QML type, and displays the detected gesture in a text type.

QtSensors .shake gesture is available with the Qt Sensors API, but the QtSensors .SecondCounter sensor gesture is provided as example code for the Qt Sensors - SensorGesture QML Type example


 Item {
    SensorGesture {
        id: sensorGesture
        enabled: false
        gestures : ["QtSensors.shake", "QtSensors.SecondCounter"]
        onDetected:{
            detectedText.text = gesture
        }
    }
    Text {
        id: detectedText
        x:5
        y:160
    }
 }
