Qt Bubble Level is a simple application that uses accelerometer sensor information to calculate the inclination of the device and presents this as a traditional Bubble level. The application provides a calibration feature to handle any possible errors in accelerometer readings.
The UI is made using Qt Quick and the engine gets the accelerometer data via the QtMobility QAccelerometer sensor.
Notes:
The application is compatible with Qt 4.7.1 and Qt Mobility 1.1.
