Thanks for the suggestions but I have managed to get FreeHEP Vector Graphics library working the way I want to. I am sharing the code below in case anyone runs into the same questions.
The above-named library has a very nice built-in export menu, which handles the export to a bunch of different formats. Code excerpt from the modified ′ModelGraphMouse′ class:
protected void handlePopup(MouseEvent e) {
final VisualizationViewer<MyNode, MyEdge> vv = (VisualizationViewer<MyNode, MyEdge>)e.getSource();
Point2D p = e.getPoint();
GraphElementAccessor<MyNode, MyEdge> pickSupport = vv.getPickSupport();
if(pickSupport != null) {
final MyNode v = pickSupport.getVertex(vv.getGraphLayout(), p.getX(), p.getY());
// if clicked on a vertex -> show info popup
// else show contexual menu
if(v != null) {
JFrame popup = new JFrame("Node: " + v.getId());
popup.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
...
} else{
JPopupMenu menu = new JPopupMenu();
JMenuItem exportGraphMenuItem = new JMenuItem("Export graph to vector image...");
exportGraphMenuItem.addActionListener(new ExportActionListener((WritingVisualizationViewer<V, E>) vv));
menu.add(exportGraphMenuItem);
menu.show(e.getComponent(), e.getX(), e.getY());
}
}
}
and the action listener:
public class ExportActionListener implements ActionListener{
private VisualizationViewer<V, E> wvv;
public ExportActionListener(VisualizationViewer<V, E> vv) {
this.wvv = vv;
}
@Override
public void actionPerformed(ActionEvent e) {
ExportDialog export = new ExportDialog();
export.showExportDialog(wvv, "Export view as ...", wvv, "export");
}
}
