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 } }
Qt Sensor Gestures contains a list of currently supported sensor gestures and their descriptions.
