jgraph布局不起作用

Question

我使用jgraph版本。5.14.0.0。( http://www.jgraph.com )

当我尝试将布局应用于jgraph时，但由于某种奇怪的原因，它不起作用。

public static void layout(JGraph graph) {
    JGraphFacade facade = new JGraphFacade(graph);
    JGraphSimpleLayout lay = new JGraphSimpleLayout(JGraphSimpleLayout.TYPE_RANDOM, 100, 100);
    lay.run(facade);
}

我运行此代码来布局图形，但单元格不会移动。

我没有找到jgraph库的标签。

基于http://anonsvn.jboss.org/repos/jbossas/projects/mc-tools/grapher/trunk/src/main/java/org/jboss/mctools/grapher/layout/ReflectionGraphLayout.java，您只遗漏了几行：

final JGraphSimpleLayout graphLayout =
    new JGraphSimpleLayout(JGraphSimpleLayout.TYPE_RANDOM, 100, 100);
final JGraphFacade graphFacade = new JGraphFacade(jgraph);
graphLayout.run(graphFacade);
final Map nestedMap = graphFacade.createNestedMap(true, true);
jgraph.getGraphLayoutCache().edit(nestedMap);
