Hi Robert, J-S
As always, thanks again for the help, it is greatly appreciated.
I was able to solve this issue by calling
void VOSGTiledViewer::paintGL()
{
getGraphicsWindow()->setClearMask( GL_COLOR_BUFFER_BIT |
GL_DEPTH_BUFFER_BIT );
getGraphicsWindow()->clear();
getGraphicsWindow()->setClearMask( 0 );
frame();
}
If I don't reset the clearmask before calling frame, I don't see my
views, but the above solution gets met out of the hole. I will have a
look again at using QWidget - I went with the EmbeddedWindow approach
because we are only using OSG in single threaded mode (by design) and
it seemed simpler. Although, things like this might point to that
being false economy, maybe I need to redesign :)
Cheers,
Morne
