Hi,
Is there a way to distinguish if the added item is a node or a link, in the method ItemAdded?

Hi,

You could use the instanceof operator:

Code
Select All
@Override
public void itemAdded(ItemEvent e)
{
	if (e.getItem() instanceof DiagramNode)
	{
		// ...
	}
}


I hope that helps,
Stoyan

Try this:

Code
Select All
PointList linkPoints = link.getControlPoints();
PointF startPoint = linkPoints.get(0);


I hope that helps,

Ok, thank you...
Is there a way to decide the length of a link? Or a way to move a node i.e. give other coordinates to a node?

You can find link's length by calling its getLength() method; move a node by calling moveTo or setBounds method.

I hope that helps,
