阅读更多关于 JGraphx : How to avoid adding edges over each other?

问题 I'm working on an application using jGraphx and I want to know how to avoid creating edges over each other. When I add 2 edges between 2 vetexes, the 2 edges are above eatch other.. Thanks in advance. EDIT : That's what I get, those are 2 edges with the labels : "dist = 1" and "dist = 4" above each other. 回答1: It can be done easily: new mxCircleLayout(graph).execute(graph.getDefaultParent()); new mxParallelEdgeLayout(graph).execute(graph.getDefaultParent()); 回答2: Without seeing any of your

问题 Is it possible to use jgraphx with JavaFx 2.0? I have tried using the below code, but i could not add the graph component to the JavaFx component. 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(); }

问题 I need to parse XML to a graph in JGraphX using Java. I get this XML from the JGraphX library and need to again set a graph by this XML. Is there any JGraphX library method that converts XML to a graph? I have this this below code to get XML from a graph: try { System.out.println("call xml getting code"); mxCodec codec = new mxCodec(); String xml = mxUtils.getXml(codec.encode(graph1.getModel())); java.io.FileWriter fw = new java.io.FileWriter("E:\\my-file.xml"); fw.write(xml); fw.close(); }

问题 I'm trying to customize a layout of jGraph. i Want to create curve edges, but I have a problem. Every time i create a group of vertex on JGraph, and I firing an event to update this graph, the edge is missing points compared to the previous state. Here is a exemple: http://i.stack.imgur.com/QrQIL.png Can someone help me? any idea?

My graph contains rectangular vertices with single outgoing edge and the vertices of rhombus shape with two outgoing edges. I'm using mxCompactTreeLayout and mostly everything is ok except that edges of the vertices of the second type look wrong for me. I want them to look like in the picture Instead, edges connected to the bottom segments of the rhombus. What should I do to get edges look as desired. EDIT: Added source code.

I'm using JGraphx to draw a graph inside a Swing Panel and all works fine. I try to insert two cells inside a target cell and is working, but layout is changing and all cells are not horizontal. So my example is: 1) build a graph with some cells: 2) press top botton and add two cells inside Hello: As you can see, problem is layout is not horizontal anymore, even if I call again mxHierarchicalLayout.
