and rename it to DiveObjectHelper, since it should be an QObject based class to make it easier on the QML, grantlee and widgets side to display the dive's internal data. each Q_PROPERTY defined in the DiveObjectHelper.h file can be acessed directly via it's name. So, if you are on a model that returns a dive, acess it's name by dive.name Signed-off-by: Tomaz Canabrava <tomaz.canabrava@intel.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
