/*
  This file was generated by the Qt Quick Application wizard of Qt Creator.
  QmlApplicationViewer is a convenience class containing mobile device specific
  code such as screen orientation handling. Also QML paths and debugging are
  handled here.
  It is recommended not to modify this file, since newer versions of Qt Creator
  may offer an updated version of it.
