I'm working on a visualisation tool using JUNG2. I'm trying to put in a simple button that someone can press, that makes the entire graph visible in the pane I'm looking at . I think I'm on the right path, but there's some last little bit that I'm missing. If anyone could advise, I'd greatly appreciate it: 

public void makeWholeGraphVisible() {
        RenderContext<CKNode, CKEdge> rc = vv.getRenderContext();
        BoundingRectangleCollector<CKNode, CKEdge> brc = new BoundingRectangleCollector<CKNode, CKEdge>(rc, layout);
        
        brc.compute();
        List<Rectangle2D> rectangles = brc.getRectangles();
        if(rectangles.isEmpty()) {
            return;
        }
        Rectangle2D endRect = rectangles.get(0);
        for(Rectangle2D rect : rectangles) {
            endRect.add(rect);
        }
        System.out.println(endRect.toString());
        
//        vv.setBounds(endRect.getBounds());
        vv.scrollRectToVisible(endRect.getBounds()); // This does nothing ?
    }

I think this may also be related to this stackoverflow question: http://stackoverflow.com/questions/9666094/jung2-how-to-scale-make-all-vertexes-visible

Thanks,
