Hello all,

I am trying to change the color of all outgoing links when any node has focus.

I have already added the following code to every xxxEditpart class :

public void updateFace() {
node = (XXX) ((Node) XXXEditPart.this.getModel()).getElement();
this.addMouseListener(new MouseListener(){
public void mousePressed(MouseEvent me) {
EList<Connection> temp = node.getOutgoingConnections();
System.out.println(temp.size());
for( int i = 0; i < temp.size(); i++)
{
//Set all outgoing connections to red
}
}
}

My question is how to change theIFigure appearance of the outgoingConnections returned list.

What is missing???

Thank you in advance for your help.

Hi,

May be something like this:

for (Object outLink : XXXEditPart.this.getSourceConnections()) {
	if (outLink instanceof ConnectionEditPart) {
		ConnectionEditPart outLinkPart = (ConnectionEditPart) outLink;
		outLinkPart.getFigure().setBackgroundColor(new Color(null, 255, 0, 0));
	}
}

Haven't tried though Smile

Thanks Asiri very much Very Happy

I appreciate your help. Smile

The following code do the trick:

for (Object outLink : XXXEditPart.this.getSourceConnections()) {
if (outLink instanceof ConnectionEditPart) {
ConnectionEditPart outLinkPart = (ConnectionEditPart) outLink;
outLinkPart.getFigure().setForegroundColor(new Color(null, 255, 0, 0));
}
}
