I am looking for a way how to display details of a node (as a popup) on MouseOver. Unfortunately the Jung2 tutorial does not provide any information how to implement this kind of functionality. Could anybody share a code sample or po开发者_Go百科int me to an example on the web?
use VisualizationViewer.setVertexToolTipTransformer
From the EdgeLabelDemo you can see a simple example is to use the built-in transformer:
vv.setVertexToolTipTransformer(new ToStringLabeller<Integer>());
You can also do with edges:
vv.setEdgeToolTipTransformer(new Transformer<Number,String>(){
public String transform(Number e) {
return "Edge:"+graph.getEndpoints(e).toString();
}
});
PluggableRendererDemo does this.
