jgraph布局不起作用 | jgraph布局不起作用

本文介绍了jgraph布局不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用jgraph ver。 5.14.0.0。（）

当我尝试将布局应用于jgraph时，但出于某种奇怪的原因，它不起作用。

  public static void layout JGraph图）{
 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表，但单元格不会移动。 / p>

我还没有找到jgraph库的标签。

解决方案

，你只是缺少几行：

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

I use jgraph ver. 5.14.0.0. ( http://www.jgraph.com )

When I try to apply layout to a jgraph, but for some weird reason it does not work.

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

I run this code to layout a graph, but cells does not move.

I have not found tag for jgraph library.

解决方案

Based on http://anonsvn.jboss.org/repos/jbossas/projects/mc-tools/grapher/trunk/src/main/java/org/jboss/mctools/grapher/layout/ReflectionGraphLayout.java, you are only missing a couple lines:

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);
