# Qt Sensors - ShakeIt QML Example

### ShakeIt in QML

Writing a QML application that uses the Shake QML sensorgestures type requires the following steps:

Import the Sensors Declarative module.

      import QtSensors 5.0

Add a SensorGesture QML type.

          SensorGesture {

In the SensorGesture type, specify which gesture to be used. Note that this can be a comma separated list. Here we are only interested in one gesture recognizer.

              gestures : ["QtSensors.shake", "QtSensors.whip", "QtSensors.twist", "QtSensors.cover",
                  "QtSensors.hover", "QtSensors.turnover", "QtSensors.pickup", "QtSensors.slam" , "QtSensors.doubletap"]

Use the 'enabled' property to start the sensor gesture.

              enabled: true

Use the onDetected signal to do stuff.

              onDetected:{
                  console.debug(gesture)
                  label.text = gesture

                  if (gesture == "shake") {
                      window.state == "rotated" ? window.state = "default" : window.state = "rotated"
                      timer.start()
                  }
                  if (gesture == "whip") {
                      window.state == "whipped" ? window.state = "default" : window.state = "whipped"
                      timer.start()
                  }
                  if (gesture == "twistRight") {
                      window.state == "twistedR" ? window.state = "default" : window.state = "twistedR"
                      timer.start()
                  }
                  if (gesture == "twistLeft") {
                      window.state == "twistedL" ? window.state = "default" : window.state = "twistedL"
                      timer.start()
                  }
                  if (gesture == "cover") {
                      window.state == "covered" ? window.state = "default" : window.state = "covered"
                      timer.start()
                  }
                  if (gesture == "hover") {
                      window.state == "hovered" ? window.state = "default" : window.state = "hovered"
                      timer.start()
                  }
                  if (gesture == "turnover") {
                      window.state = "default"
                      loopy2a_mono.play();
                      timer.start()
                  }
                  if (gesture == "pickup") {
                      window.state = "default"
                      phone.play()
                      timer.start()
                  }
                  if (gesture == "slam") {
                      window.state == "slammed" ? window.state = "default" : window.state = "slammed"
                      timer.start()
                  }
                  if (gesture == "doubletap") {
                      window.state == "doubletapped" ? window.state = "default" : window.state = "doubletapped"
                      timer.start()
                  }
              }

There are additional gestures to shake which are supported: whip, twistRight, hover, cover, turnover and pickup.
