Re: Mouse events in graphstream

[guilhelm savin <guilhelm.savin AT gmail.com>]

Hi Stephen and welcome,

Viewer is composed of View and these views are JPanel,

so you can use classic method of swing with them !

Here is an example to add a MouseListener to a View :

-------------------

import org.graphstream.ui.swingViewer.View;

import org.graphstream.ui.swingViewer.Viewer;

Graph g = ...;

...

Viewer v  = new Viewer(g, Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);

View   vi = v.addDefaultView(true);

vi.addMouseListener(new MyMouseListener());

-------------------

Hope this helps.

Regards.

Hello,

I'm trying to use graphstream to visualize a large network.  I can successfully read in the network, display it and zoom in and out using the wheel on my mouse.  To zoom I use the java.awt.event.MouseWheelListener class.  I'd like to allow panning side to side or up and down by clicking and holding the mouse button and dragging, but I can't seem to make this work.  Is there a way in graphstream to capture mouse events in the view?  I see that I can do this using the ViewerListener, but the buttonPushed or buttonReleased only works when  I click a node in the graph.  I'd like panning to work regardless of where the user clicks in the view.

Thanks,
Stephen
