  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.
