JGraphXでswimlaneを表示する

JGraphXでswimlaneを表示するにはmxConstantsの以下の定数を使用します。

• STYLE_SHAPE:図形の指定
• SHAPE_SWIMLANE:swimlaneの表示
• STYLE_HORIZONTAL:水平方向の指定

サンプルコード

import java.awt.*
import javax.swing.*
import groovy.swing.*
import com.mxgraph.swing.*
import com.mxgraph.view.*
import com.mxgraph.util.mxConstants
import com.mxgraph.layout.*

def graph = new mxGraph()
def mxgc = new mxGraphComponent(graph)

sb = new SwingBuilder()
def frm = sb.frame(
  title: "JGraphX - swimlane",
  visible: true,
  size: [300, 300],
  resizable: true,
  contentPane: mxgc,
  defaultCloseOperation: WindowConstants.EXIT_ON_CLOSE
){

  parent = graph.getDefaultParent()
  graph.model.beginUpdate()
  try
  {
    def stylesheet = graph.getStylesheet()
    // シェイプのカスタムスタイル
    def style1 = [
      (mxConstants.STYLE_SHAPE): mxConstants.SHAPE_SWIMLANE,
      (mxConstants.STYLE_HORIZONTAL): false,
    ]
    stylesheet.putCellStyle("style1", style1)

    def v1a = graph.insertVertex(parent, null, "Presentation Layer",
      0, 0, 300, 100, "style1")
    def v1b = graph.insertVertex(parent, null, "Logic Layer",
      0, 100, 300, 100, "style1")

    def v2a = graph.insertVertex(v1a, null, "Display form",
      50, 35, 100, 30)
    def v2b = graph.insertVertex(v1b, null, "Validate form",
      50, 35, 100, 30)
    def v2c = graph.insertVertex(v1b, null, "Save",
      180, 35, 100, 30)

    graph.insertEdge(parent, null, "call", v2a, v2b)
    graph.insertEdge(parent, null, "call", v2b, v2c)

  }
  finally
  {
    graph.model.endUpdate()
  }
}
