GraphStream usage issue

[Bilal Najeeb <bilal.najeeb2011 AT gmail.com>]

Greetings everyone,

I am Bilal, a software engineer from Pakistan. First of all i would like to tell you that the graphstream library is admirable, great work.

I am currently working on a project in which i have to generate some graphical output and I am using graphstream. From the tutorial given on the website, it is working fine when i make a separate test project in net beans for interactive graph which would respond to click events but when i try to do the same thing in the project I am working on, the graph wont appear just a Jframe and that too even wont close when i click on the cross button. I am pasting my code below kindly help me out. I shall be very great-full to you guys.

This is the code of the button click event from another Jframe

private void btnGraphStreamActionPerformed(java.awt.event.ActionEvent evt) {                                               

        new Clicks();

    }  

and this is the code where the graph will actually be made

package forms;

import org.graphstream.graph.Graph;

import org.graphstream.graph.implementations.SingleGraph;

import org.graphstream.ui.view.Viewer;

import org.graphstream.ui.view.ViewerListener;

import org.graphstream.ui.view.ViewerPipe;

public class Clicks implements ViewerListener{

    protected boolean loop = true;

    public Clicks() {

Graph graph = new SingleGraph("Clicks");

Viewer viewer = graph.display();

viewer.setCloseFramePolicy(Viewer.CloseFramePolicy.EXIT);

                graph.addNode("A");

                graph.addNode("ch");

graph.addNode("2");

ViewerPipe fromViewer = viewer.newViewerPipe();

fromViewer.addViewerListener(this);

fromViewer.addSink(graph);

while(loop) {

fromViewer.pump();

}

}

public void viewClosed(String id) {

loop = false;

}

public void buttonPushed(String id) {

System.out.println("Button pushed on node "+id);

}

public void buttonReleased(String id) {

System.out.println("Button released on node "+id);

}

}

kindly reply me as soon as possible.

Regards
