详细描述

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
     }
  }
