Re: creating effects like in your YouTube video

Oh I am sorry I should have included this in the last message as well:

public void showDynamicGraph() throws IOException {

g2.addAttribute("ui.quality");

g2.addAttribute("ui.antialias");

g2.addAttribute("ui.stylesheet", "graph {fill-color: #666666;} " +

"node {size: 3px; text-visibility-mode: hidden;} " +

"edge {size: 1px; fill-color: #FFFFFF; text-size: 6;}");

try {

fs.begin("C:/filename.dgs");

while (fs.nextEvents()) {

try {

Thread.sleep(10);

}

catch(Exception e) {

e.printStackTrace();

}

}

} catch( IOException e) {

e.printStackTrace();

}

try {

fs.end();

} catch( IOException e) {

e.printStackTrace();

} finally {

fs.removeSink(g2);

}

}

Thank you.  That is very helpful.   I will keep reading and studying.  I tried the following but got a blank graph:

Regards,

Keith

public class Visual implements MouseListener {

// variable declarations

etc ...............

public Visual() {

System.setProperty("gs.ui.renderer", "org.graphstream.ui.j2dviewer.J2DGraphRenderer");

g2 = new DefaultGraph("2");

try {

fs = FileSourceFactory.sourceFor("C:/filename.dgs");

} catch (IOException e) {

e.printStackTrace();

}

fs.addSink(g2);

x = 0;

y = 0;

viewer  = new Viewer(g2, Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);

view = viewer.addDefaultView(true);

view.addMouseListener(this);

}

@Override

public void mouseClicked(MouseEvent e) {

x = e.getX();

y = e.getY();

view.setViewCenter(x,y,0);

}

etc .......

In fact ViewerListener and swing MouseXListener are

complementary. MouseXListener allow to get pure graphic

events :

- wheel motion ;

- mouse motion ;

- mouse clicks.

Whereas ViewerListener allows to get events related

to the graph :

- there is a click on a node ;

- a view is closed.

You can read this previous thread where we explain

how to use MouseXListener with GraphStream view :

Hope this helps !

Hi Guilhelm,

Thank you. I am glad to be a part of the community.  The links you sent were very helpful.  I think I would like to start by getting the graph to center on a spot when clicked and zoom in/out according to the mouse wheel.  I am trying to use the Clicks class from the tutorial as an example but I don't really understand what I need to implement in each of the three methods.  I assume that in the buttonPushed and buttonReleased methods, I specify what happens on a mouse click.  Is this different from using javax.swing.event.MouseInputListener?

Thank you for your help.

Regards,

Keith

Hi Keith,

and welcome to the GraphStream community. You should have

a look to the "Graph Visualization" part of the documentation

http://graphstream-project.org/doc/Tutorials/Graph-Visualisation_1.0/

You can also have a look on the "style" part :

http://graphstream-project.org/doc/Tutorials/GraphStream-CSS-Reference_1.0/

I just post the sources used to generate some frames of the

1.0 video on the web site, in the "Download" section. For example,

the org.graphstream.videos.r10.IMDB could be a good example of

zooming and translating in the view.

If some informations are missing, please ask.

Regards.

Hello,

I am new to Graphstream and also new to using the graphical type components of
Java.  I have been able to read in data, create a dgs file and draw the graph
dynamically.  Now I would like to be able to zoom in on individual clusters /
subgraphs.  What topics should I look at (both in graphstream api and in Java)?

Thank you,
Keith
