Can I change the width of the conection line? I want to
let user set the line width while connecting from different
nodes. Appreciated for any reply.

If you are using the standard PolylineConnection in your connection edit
part, you can override the createFigure() method of the
AbstractConnectionEditPart like the following:

protected IFigure createFigure() {
PolylineConnection conn =
(PolylineConnection) super.createFigure();
conn.setLineWidth(10);
return conn;
}

Hope this helps.

Appreciated for reply.
But if I use XYAnchor to set up a line, how to change the width of XYAnchor
Connection?
I can not find the method that draws the connection from XYAnchor. Where is
the method?
It would be great if I can override that method. Appreciated for any reply.

Thanks Scott. Your idea just gave me some clues and solved
the problem. Because it helps me to think that the XYAnchor
connection might be also drawn from a PolylinConnection, I
find it is refreshed in AbstractConnectionEditPart # refreshTargetAnchor()

Thus All I have to let myLineEditPart inherits AbstractConnectionEditPart
and overwrites the method like this:

protected void refreshTargetAnchor() {
int width = 5;
if(connection instanceof PolylineConnection){
((PolylineConnection)connection).setLineWidth(width);
}
}

Then the line width is set.

Thanks
