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