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.
