    <p>Since I couldn't find any specific place to discuss this, I thought I'd post here... I'm using graphstream 1.1 (<a href="http://graphstream-project.org/" rel="nofollow">http://graphstream-project.org/</a>), a graph visualization library for java, to develop a data visualization tool. I'm needing to retrieve mouseclicks on nodes to display related data, but after following the library tutorial, it's still not clear for me how to do this. Does anyone that used this could help me out here with a more straightfoward answer? The tutorial I'm following is at:</p> <p><a href="http://graphstream-project.org/doc/Tutorials/Graph-Visualisation_1.0/#retrieving-mouse-clicks-on-the-viewer" rel="nofollow">http://graphstream-project.org/doc/Tutorials/Graph-Visualisation_1.0/#retrieving-mouse-clicks-on-the-viewer</a></p> <pre><code>public class Clicks implements ViewerListener { protected boolean loop; public static void main(String args[]) { new Clicks(); } public Clicks() { // We do as usual to display a graph. This // connect the graph outputs to the viewer. // The viewer is a sink of the graph. Graph graph = new SingleGraph("Clicks"); Viewer viewer = graph.display(); // The default action when closing the view is to quit // the program. viewer.setCloseFramePolicy(Viewer.CloseFramePolicy.HIDE_ONLY); // We connect back the viewer to the graph, // the graph becomes a sink for the viewer. // We also install us as a viewer listener to // intercept the graphic events. ViewerPipe fromViewer = viewer.newViewerPipe(); fromViewer.addViewerListener(this); fromViewer.addSink(graph); // Then we need a loop to wait for events. // In this loop we will need to call the // pump() method to copy back events that have // already occured in the viewer thread inside // our thread. while(loop) { fromViewer.pump(); } } viewClosed(String id) { loop = false; } buttonPushed(String id) { System.out.println("Button pushed on node "+id); } buttonReleased(String id) { System.out.println("Button released on node "+id); } } </code></pre>

    1. COAre you getting caught up somewhere? Can you post a more specific question such as errors? Unexpected behaviors?

    2. COMy code is preety much the same of the tutorial. Just changed the declarations of the functions at the end to make it possible to compile. The listener seems not to be detecting the clicks. It's supposed to print on console the node's id when I click, but nothing happens... not even a exception. The console remains clean.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
