通过将JGraphX添加到JLable可以显示它吗?
许多testJGraphX(如下)取自JGraphX Hello World示例,但该图形未显示在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);
}
}
最佳答案
JPanel应该可以工作,或者实际上可以直接将其添加到JFrame中。
编辑-下面的代码对我来说很好。
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);
}
}
