java - 如何最好地显示 JGraphX？

Question

是否可以通过将 JGraphX 添加到 JLable 来显示它？ testJGraphX(如下)的大部分内容取自 JGraphX Hello World 示例，但该图未显示在 jLable1 中。 对于 JGraphX，是否有比 JLabel 更好的容器？

public class TestJGraphX extends javax.swing.JFrame implements TableModelListener {
    public TestJGraphX() {
        initComponents();
        testJGraphX();
    }
    private void initComponents() {
        jLabel1 = new javax.swing.JLabel();
  ...
  .addComponent(jLabel1, javax.swing.GroupLayout.DEFAULT_SIZE, 304, Short.MAX_VALUE)
  ...
  .addComponent(jLabel1, javax.swing.GroupLayout.DEFAULT_SIZE, 170, Short.MAX_VALUE))
  ...
 }
    private void testJGraphX() {
        mxGraph graph = new mxGraph();
        Object parent = graph.getDefaultParent();
        graph.getModel().beginUpdate();
        try {
            Object v1 = graph.insertVertex(parent, null, "Hello", 20, 20, 80, 30);
            Object v2 = graph.insertVertex(parent, null, "World!", 240, 150, 80, 30);
            graph.insertEdge(parent, null, "Edge", v1, v2);
        } finally {
            graph.getModel().endUpdate();
        }
        mxGraphComponent graphComponent = new mxGraphComponent(graph);
        jLabel1.add(graphComponent);
    }
}

JPanel 应该可以工作，或者直接将其添加到 JFrame 中即可。

编辑 - 下面的代码对我来说显示了很好的图表。

import javax.swing.JFrame;

import com.mxgraph.swing.mxGraphComponent;
import com.mxgraph.view.mxGraph;

public class GraphFrame extends JFrame {
    public static void main(String[] args) {
        mxGraph graph = new mxGraph();
        Object parent = graph.getDefaultParent();
        graph.getModel().beginUpdate();
        try {
            Object v1 = graph.insertVertex(parent, null, "Hello", 20, 20, 80,
                    30);
            Object v2 = graph.insertVertex(parent, null, "World!", 240, 150,
                    80, 30);
            graph.insertEdge(parent, null, "Edge", v1, v2);
        } finally {
            graph.getModel().endUpdate();
        }
        mxGraphComponent graphComponent = new mxGraphComponent(graph);

        GraphFrame frame = new GraphFrame();
        frame.add(graphComponent);
        frame.pack();
        frame.setVisible(true);
    }
}
