Hi,

I am working on an application with Osg (OsgEarth) integrated in QtQuick.
I am trying to make ON_DEMAND framescheme working without using the timer 
method in order to make it 'event' based instead of continuously requesting if 
a new frame is necessary.

The solution is now working in most cases, but i wonder now how to be notified 
when the DatabasePager requires an update SceneGraph. Is it possible ? Is there 
a kind of signal emited each time a new item is added in _dataToMergeMist ? or 
a callback ?


Thank you!

Cheers,
Jérôme
