Qt Sensors - Accel Bubble
The AccelBubble example demonstrates the Accelerometer QML type.
Overview
Writing a QML application that uses the Accelerometer QML sensors type requires the following steps:
Import the Sensors Declarative module.
import QtSensors 5.0
Add an Accelerometer QML type.
Accelerometer { id: accel dataRate: 100
Use the 'active' property to start the sensor
active:true
Move the bubble according to a factor of the accelerator sensor
onReadingChanged: { var newX = (bubble.x + calcRoll(accel.reading.x, accel.reading.y, accel.reading.z) * .1) var newY = (bubble.y - calcPitch(accel.reading.x, accel.reading.y, accel.reading.z) * .1) if (isNaN(newX) || isNaN(newY)) return; if (newX < 0) newX = 0 if (newX > mainWindow.width - bubble.width) newX = mainWindow.width - bubble.width if (newY < 18) newY = 18 if (newY > mainWindow.height - bubble.height) newY = mainWindow.height - bubble.height bubble.x = newX bubble.y = newY }
