정 그래프의 레이아웃을 변경하기 위해 q 메뉴 바를 어떻게 추가 할 수 있습니까? 예 : StaticLayout, SpringLayout 등? 이jung을 사용하여 그래프의 레이아웃을 변경하는 메뉴를 추가하는 방법
Infact는 내가 이미 가지고있는 것입니다 :
내 code.Thanks에 따라 무엇을 나에게 제시하는 경우가 좋은 것, 그래서 내가 자바에 새로운 오전 죄송합니다JFrame frame = new JFrame("JUNG2 based GraphVisualization Tool");
// Create a graph
SparseMultigraph<MyNode, MyEdge> graph = new SparseMultigraph<MyNode, MyEdge>();
// We want to give the Nodes a point where to be (for later use)
//Map<MyNode, Point2D> vertexLocations = new HashMap<MyNode, Point2D>();
// Also we need a Layout
Layout<MyNode, MyEdge> layout = new StaticLayout(graph);
layout.setSize(new Dimension(600, 600));
// VisualizationViewer to Visualize our nodes and edges
VisualizationViewer<MyNode, MyEdge> vv = new VisualizationViewer<MyNode, MyEdge>(layout);
vv.setPreferredSize(new Dimension(650, 650));
// To show the vertex and EdgeLabels
vv.getRenderContext().setVertexLabelTransformer(new ToStringLabeller());
vv.getRenderContext().setEdgeLabelTransformer(new ToStringLabeller());
// Our mouse should be usable in different modes
EditingModalGraphMouse mouse = new EditingModalGraphMouse(vv.getRenderContext(), MyNodeFactory.getInstance(), MyEdgeFactory.getInstance());
// Default values for new edges
MyEdgeFactory.setDefaultCapacity(100.0);
MyEdgeFactory.setDefaultWeight(5.0);
// Popupmenu
PopupNodeEdgeMenuMousePlugin nodeEdgePlugin = new PopupNodeEdgeMenuMousePlugin();
JPopupMenu nodeMenu = new MyMouseMenus.NodeMenu();
JPopupMenu edgeMenu = new MyMouseMenus.EdgeMenu(frame);
nodeEdgePlugin.setNodePopup(nodeMenu);
nodeEdgePlugin.setEdgePopup(edgeMenu);
// The already existing popup editing plugin has to be removed
mouse.remove(mouse.getPopupEditingPlugin());
// And the new one has to be added
mouse.add(nodeEdgePlugin);
// set up the new mouse for the VisualizationViewer
vv.setGraphMouse(mouse);
// A JFrame to show all the stuff
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(vv);
// To change the mouse modes, the tutorial shows a menuBar. Think it would be nice to have a toolbar here!
JMenuBar menuBar = new JMenuBar();
JMenu modeMenu = mouse.getModeMenu();
modeMenu.setText("Mouse Mode");
modeMenu.setIcon(null);
modeMenu.setPreferredSize(new Dimension(80,20));
menuBar.add(modeMenu);
frame.setJMenuBar(menuBar);
mouse.setMode(ModalGraphMouse.Mode.EDITING);
frame.pack();
frame.setVisible(true);
