mxGraph 设置默认Edge样式

在mxgraph Swing 操作中，单击某个cell连接其他cell的节点线是，默认样式是直线连接，没有节点弯曲的设置。可以修改mxgraph的jar包中的mxStylesheet.java 对应的createDefaultEdgeStyle方法，在其中添加：style.put("edgeStyle", mxEdgeStyle.ElbowConnector); 即可。

/**
* Creates and returns the default edge style.
*
* @return Returns the default edge style.
*/
protected Map<String, Object> createDefaultEdgeStyle()
{
Map<String, Object> style = new Hashtable<String, Object>();
style.put(mxConstants.STYLE_SHAPE, mxConstants.SHAPE_CONNECTOR);
style.put(mxConstants.STYLE_ENDARROW, mxConstants.ARROW_CLASSIC);
style.put(mxConstants.STYLE_VERTICAL_ALIGN, mxConstants.ALIGN_MIDDLE);
style.put(mxConstants.STYLE_ALIGN, mxConstants.ALIGN_CENTER);
style.put(mxConstants.STYLE_STROKECOLOR, "#6482B9");
style.put(mxConstants.STYLE_FONTCOLOR, "#446299");
style.put("edgeStyle", mxEdgeStyle.ElbowConnector); //新添加的样式

return style;
}

这个文件里面也可以修改 Cell样式，方法是：

/**
* Creates and returns the default vertex style.
*
* @return Returns the default vertex style.
*/
protected Map<String, Object> createDefaultVertexStyle()
{
Map<String, Object> style = new Hashtable<String, Object>();

style.put(mxConstants.STYLE_SHAPE, mxConstants.SHAPE_RECTANGLE);
style.put(mxConstants.STYLE_PERIMETER, mxPerimeter.RectanglePerimeter);
style.put(mxConstants.STYLE_VERTICAL_ALIGN, mxConstants.ALIGN_MIDDLE);
style.put(mxConstants.STYLE_ALIGN, mxConstants.ALIGN_CENTER);
style.put(mxConstants.STYLE_FILLCOLOR, "#C3D9FF");
style.put(mxConstants.STYLE_STROKECOLOR, "#6482B9");
style.put(mxConstants.STYLE_FONTCOLOR, "#774400");

return style;
}
