如何最好地显示JGraphX?

jlabel graph java

jacknad · 技术社区 · 15 年前

可以通过将JGraphX添加到JLable中来显示它吗? testJGraphX的大部分内容(如下)取自JGraphX Hello World示例,但jlabel1中不显示该图。有没有比JLabel更适合JGraphX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,或者直接添加到JFrame中。

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);
    }
}
