Event on Arrow Creation?

Hi,

I'm looking for a way to handle a user drawing an arrow from a node to another arrow. I don't need to join on the destination arrow, I just need to know when that particular series of events has occurred. Is there any way to achieve this?

Thanks,
Matt

Hi,

The "Ternary connections"  example shows something of that kind. It uses the AllowUnconnectedArrows property, which allows drawing an arrow to any point of the document, even if there isn't any node there. The ArrowCreated event handler checks whether there is another arrow at the point whether the new arrow is created by using the GetArrowAt method -

Code
Select All
private void fc_ArrowCreated(object sender, MindFusion.Diagramming.WinForms.ArrowEventArgs e)
{
	Arrow a = e.Arrow;

	// if not connected to a real node
	if (a.Destination is DummyNode)
	{
		PointF endPt = a.ControlPoints[a.ControlPoints.Count - 1];
		a.Locked = true;// so we can exclude it from the search
		Arrow trg = fc.GetArrowAt(endPt, 1, true);
		if (trg != null)
		{
			...


I hope that helps,
Stoyan

Thanks Stoyo, I'll look into that.
