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.
