## Detailed Description

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
         }
      }
