Double-click action on edges

[tainlan]

Hi,
My plugin need to define a own action when double - clicking on
edges.
However, in cytoscape editor, the double-click action is that the
editor's SIF-interpreter is invoked.

Is there any way to remove or inhibit the SIF-interpreter action from
a network?
If so, how could I do this?

Thanks!

Hi,
Here is how I did:
1. Create a mouse listener class:
public class ListenMouse implements MouseListener, MouseMotionListener
{

2. Add mouse listener to network:
public ListenMouse(){

view=Cytoscape.getCurrentNetworkView();
((DGraphView) view).getCanvas().addMouseListener(this);
((DGraphView) view).getCanvas().addMouseMotionListener
(this);

}

3. Detect mouse click:
public void mouseClicked(MouseEvent e){
EdgeView ev =((DGraphView) view).getPickedEdgeView
(e.getPoint ());
if (ev!=null){//if click on an edge, do something here}

Hope this helps.

Hi,

 

I would like to enquire about the things to add to my code shown below.

I want to get my mouse listener to detect and display a message when the mouse cursor enters a node.

How should I add the mouse listener?

 

public class MouseTest extends CytoscapePlugin
{ 
    public MouseTest()
    {
        MouseListenerTest mlt = new MouseListenerTest(this);
       
        Cytoscape.getDesktop().addMouseListener(mlt);      
        
    }
   
    public class MouseListenerTest implements MouseListener   

    {
        CyNetworkView view;
        public MouseListenerTest(MouseTest myPlugin)
        {
            view = Cytoscape.getCurrentNetworkView();
            ((DGraphView) view).getCanvas().addMouseListener(this);
         }
        public void mouseClicked(MouseEvent e)  { }

        public void mousePressed(MouseEvent e) { }
        public void mouseReleased(MouseEvent e) {}
        public void mouseEntered(MouseEvent e)
        {
                         JOptionPane.showMessageDialog(Cytoscape.getDesktop(), "Mouse Entered");
        }
        public void mouseExited(MouseEvent e) {}

}

 

Thanks!
