Java Prefuse图将节点复制到另一个图

Question

I have a 2x2 grid of graphs in JPanels. In the top left graph i have a load of nodes, when I click on a node I want that node to be copied to the next graph so it appears there. Firstly I am making the graphs Then I add data to the top left graph Then I attach those graphs to panels by creating visualisation, and a display based on that visualization. I add a ControlListener to the display to handle clicking on nodes - I pass that the graph I want the node to be copied into Then in the itemClicked method, I am doing Node node = graph.addNode(). I get no errors, but I dont see the node either. Any ideas why - do I have to refresh the graph or something?

通过在添加节点的可视化文件上运行操作列表来刷新图形。
