CreateDiagramLink for TableNode with option LeftInRightOut

Hi,

Thanks to Diagramming for JavaScript, V4.1, it is possible to
create diagram links between table node rows (by the createDiagramLink method).

How can we create links between table node rows with the extra specification that:
- all incoming links should connect with the table node at the left side,
- and all outgoing links should connect with the table node at the right side?

I know that by AnchorPattern a property LeftInRightOut exists, but this does not apply on the createDiagramLink method..

Thanks in advance.

MF.

Hi,

On some platforms we have row.anchorPattern property that would be applied in this situation, but it's not available in JS diagram yet. You could adjust start/end points after creating a link:

Code
Select All
DiagramLink.prototype.rightToLeft = function()
{
	var start = this.startPoint;
	start.x = this.origin.bounds.right();
	this.startPoint = start;

	var end = this.endPoint;
	end.x = this.destination.bounds.left();
	this.endPoint = end;

	this.updateFromPoints();
}

var l = diagram.factory.createDiagramLink(table1, 1, table2, 3);
l.rightToLeft();


and e.g. call the method also from linkCreated event handler for links drawn by users.

Regards,
Slavcho
