     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.
