Need Custom Shaped Selection Handle

Hi Stoyan,

In our application, we have some custom shaped ShapeNode(like pentagon, hexagon and  etc.)

We are using DrawAdjustmentHandle() of diagram to draw selection rectangle for these shapes, but we are not able to find any method which accepts Shape as an argument.

Please suggest how we can draw Custom Selection Handle for our Custom Shaped Nodes.

Thanks
Bala

Hi Bala,

Do you need to draw a selection border with the same shape as the node? You could use the Shape.Draw method for that. It draws the shape with its definition coordinates in the 0-100 range, so you will need to first apply a scale transform such as dc.ScaleTransform(nodeWidth / 100, nodeHeight / 100) .

I hope that helps,
Stoyan

Hi Anshul,

It seems you are using an older version that does not have a public Shape.Draw method. Try the following instead:

Code
Select All
if (e.Item is DiagramNode)
{
	DiagramNode node = e.Item as DiagramNode;
	e.Graphics.DrawGeometry(null, new Pen(Brushes.Red, 3), node.GetRegion());
	...


I hope that helps,
Stoyan
