jgraphx更改顶点大小

Question

I draw a simple graph (using Java swing interface).

The graph is OK, but the default / automatic vertices size is small for my purpose. How to set the vertex size (rectangle or ellipse)?

I can change some graph behavior using put() ( like put(mxConstants.STYLE_SHAPE, mxConstants.SHAPE_ELLIPSE)) but not the size of vertices.

The graph is OK, but the default / automatic vertices size is small for my purpose. How to set the vertex size (rectangle or ellipse)?

May I have misunderstood many about jgraphx?

The documentation is very difficult to understand, very cryptic (at least for me), can I have suggestions for books or links for better understand jgraphx for Java.

One more detail: the graph isn't built element by element, but it come from a graph built with jgraphT using jGraphXAdapter

JGraphXAdapter<Incrocio, Strada> graphAdapter = new JGraphXAdapter<Incrocio, Strada>(listenableGraph);

Thank to Andrew for her patience. English is not my language, and sometime I make a mistakes even in italian (my native language). Add that I'm new in Java. New even in this forum (an related rules, and this may not be the right place for my replay). I've not read your message previous with the due attention.

I put the code, whith a partial solution, I hope it's more clear.

package it.rex.view;

public class StradarioViewBis2 extends JFrame {

    private JPanel contentPane;

    // listenableGraph is a complete graph done with JgraphT
    public StradarioViewBis2(ListenableGraph<Incrocio, Strada> listenableGraph) {

        JGraphXAdapter<Incrocio, Strada> graphAdapter = 
                new JGraphXAdapter<Incrocio, Strada>(listenableGraph);

        //graphAdapter.getStylesheet().getDefaultEdgeStyle().put(mxConstants.STYLE_NOLABEL, "1");  //remove label from edge

        graphAdapter.getModel().beginUpdate();
        try {
            graphAdapter.clearSelection(); 
            graphAdapter.selectAll();
            Object[] cells = graphAdapter.getSelectionCells(); //here you have all cells

            // Iterate into graph to change cells
            for (Object c : cells) {
                mxCell cell = (mxCell) c; //cast
                mxGeometry geometry = cell.getGeometry();

                if (cell.isVertex()) { //isVertex
                    // Here I can change vertex dimensions 
                    geometry.setWidth(40);
                    geometry.setHeight(40);
                }else{ //is not a vertex, so u can get source and target 
                    //  cell.setStyle("orthogonalEdgeStyle"); 
                    //  cell.getChildAt(x); //Returns the child at the specified index. (target)
                }
            }
        }
        finally
        {
            graphAdapter.getModel().endUpdate();
        }

        mxIGraphLayout layout = new mxCircleLayout(graphAdapter);  // questo sistema le posizione degli elementi

        layout.execute(graphAdapter.getDefaultParent());

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 550, 450);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(null);

        mxGraphComponent graphComponent = new mxGraphComponent(graphAdapter);  // is JScrollPane extension 

        graphComponent.setPageVisible(true);
        graphComponent.setBounds(30, 30, 300, 300);
        contentPane.add(graphComponent);

        //graphComponent.setEnabled(false);
        graphComponent.getViewport().setBackground(Color.white);
        ;

    }

}

After some tries, I've found that the vertex's size is back to initial dimension when I change the cell's label, not when I move the focus away from cell.

I think I need to change the default behavior of the graph, but i'm not yet discovered how.

This is the result, after editing label on top vetex: enter image description here
