Hi Kevin,

I'm trying to use you branch in a new application (an ontology viewer) including directly the \
dotgraphview. It will start from an empty graph and programatically add its content.

Here is how I try to do:

  Q_FOREACH( Soprano::Statement s, it.allElements() )
  {
    qDebug() << s.predicate().toString();
    
    KGraphViz::GraphNode* node = m_primaryGraph->graph()->addNewNode(s.predicate().toString());
    node->setShape("box");
  }

  m_primaryGraph->graph()->update();
  m_primaryGraph->slotUpdate();
  m_primaryGraph->displayGraph();


But all what I get is the qDebug output (I get no output from kDebug even if configured with fulldebug \
and kdebugdialog activated, but that'is another issue) and:

(4235) Dot2QtConsts::qtFont: Unknown dot font ' "" '. returning Qt default.

Something must be badly initialized but I cannot find what. 

Any idea ?

Gaël
