我实现了图像的拖放,现在我想在调整大小时限制图像的比例。
/**
* Variable: constrainChildrenOnResize
*
* Specifies if children should be constrained according to the <constrainChildren>
* switch if cells are resized (including via <foldCells>). Default is false for
* backwards compatiblity.

我有一个简单的服务器-客户端架构。我想用javascript在客户端使用自定义xml创建mxgraph。下面是我的xml的结构:
<mycustomroot>
<!-- some not mxgraph related tags -->
<some-custom-tag>
......
</some-custom-tag>
<!-- this is standard mxgraph model-->
<mxGraphModel>
......
</mxGraphModel>
<!-- this
我想从编辑器中获取xml数据。
谁知道如何用javascript从mxGraph编辑器获取xml数据?
var Draw = new function __Draw() {
this.save = function () {
var graph = new Graph();
var encoder = new mxCodec();
var result = encoder.encode(graph.getModel());
var xml = encodeURIComponent(mxUtils.getXml(result
我正在用JGraphX构建一个图表。使用以下代码,与类似的图形实现(如JGraphT )相比,它需要非常长的时间来构建。为什么会这样呢?创建顶点的速度很快,但创建边的嵌套循环需要很长时间,特别是当数组大小为1000时。
Vertex[] verts = new Vertex[1000]; // My own vertex class
mxCell[] cells = new mxCell[1000]; // From com.mxGraph.model.mxCell
// Create graph
mxGraph mx = new mxGraph(); // from com.mxgraph
我是这样设置mxGraph的:
model = new mxGraphModel();
// Tell the model to manage cell ids for us
model.isCreateIds();
graph = new mxGraph(container, model);
var graphMgr = new GraphManager(graph);
var edgeMgr = new EdgeManager();
// Configure mxGraph properties, methods, an
我有以下定义

import qualified Data.Map as M
class Graph g n e | g -> n e where
empty :: g -- returns an empty graph
type Matrix a = [[a]]
