You can save your shapes to a shape library xml file, load it using ShapeLibrary.LoadFromXml method and then assign the custom shapes to nodes by setting ShapeNode.Shape = Shape.FromId(...);

I hope that helps,

Hi,

We have a Shape.AnchorPattern property in some versions of the control that let you associate anchor points directly with shapes, but it's not available yet in WPF. For time being you could implement your own association, e.g. using a shape-id to AnchorPattern dictionary, and set node.AnchorPattern when node.Shape is set to one with known id from the the dictionary.

I hope that helps,
Stoyan

Hi,

If you will be creating custom types for different shapes as you have an EvRectangle node, you could set base.AnchorPattern in their constructors and don't change it anymore:

Code
Select All
public EvRectangle()
{
	AnchorPattern = AnchorPattern.Decision2In2Out;
	....
}


For ordinary ShapeNodes you could keep a dictionary mapping shape to anchor pattern identifiers and set node.AnchorPattern from NodeCreated:

Code
Select All
private void OnNodeCreated(object sender, NodeEventArgs e)
{
	var node = e.Node as EvBaseNode;
	var shapeNode = e.Node as ShapeNode;

	if (node != null)
	{
		...
	}
	else if (shapeNode != null)
	{
		if (shapeAnchorPoints.ContainsKey(shapeNode.Shape.Id))
		{
			var anchorPointsId = shapeAnchorPoints[shapeNode.Shape.Id];
			shapeNode.AnchorPattern = AnchorPattern.FromId(anchorPointsId);
		}
	}
}

Dictionary<string, string> shapeAnchorPoints = new Dictionary<string, string> {
	{ "Rectangle", "LeftInRightOut" },
	{ "Decision", "Decision1In3Out" }
};


We'll try to port the Shape.AnchorPattern property from our WinForms control for next release.

I hope that helps,
Stoyan

hi Stoyan,
Thanks for you help, I can solve the problem on your way.
but I think the AnchorPattern.Regist method is necessary.
because the defeat AnchorPattern-points is so poor.
so I defined like this:
Code
Select All
 public class EvDefaultNodeAnchorPoint
    {
        private Dictionary<string, string> shapeAnchorPoints = new Dictionary<string, string>
        {
            {"Ellipse", "Decision4In4Out"},
            {"RSave", "Decision4In4Out"},
            {"Rectangle", "Decision4In4Out"},
            {"Alternative", "Decision4In4Out"},
            {"Arrow7", "Decision4In4Out"},
            {"Cloud", "Decision4In4Out"},
            {"ConeDown", "Decision4In4Out"},
            {"ConnectedIssues", "Decision4In4Out"},
            {"CreateRequest", "Decision4In4Out"},
            {"Cross", "Decision4In4Out"},
            {"Cylinder", "Decision4In4Out"},
            {"Database", "Decision4In4Out"},
            {"DataTransmition", "Decision4In4Out"},
            {"DividedEvent", "Decision4In4Out"},
            {"Octagon", "Decision4In4Out"}
        };

        public Dictionary<string, string> ShapeAnchorPoints
        {
            get { return shapeAnchorPoints; }
        }

        private AnchorPattern decision4In4Out =
            new AnchorPattern(new AnchorPoint[]
            {
                new AnchorPoint(50, 0, true, true, MarkStyle.None),
                new AnchorPoint(0, 50, true, true, MarkStyle.None),
                new AnchorPoint(50, 100, true, true, MarkStyle.None),
                new AnchorPoint(100, 50, true, true, MarkStyle.None)
            });

        public AnchorPattern Decision4In4Out
        {
            get { return decision4In4Out; }
        }
    }

Hi,

You could pass the "Decision4In4Out" id to AnchorPattern constructor and that isntance will be automatically registered and later returned by AnchorPattern.FromId.

I hope that helps,
Stoyan

This version adds Shape.AnchorPattern property:
https://mindfusion.eu/_beta/wpfdiag.3.2.1.zip

Once you assign your anchor pattern to shapes, you won't have to set nodes' own AnchorPattern anymore. I.e. when node.AnchorPattern is null, the control will automatically use node.Shape.AnchorPattern instead.

I hope that helps,
Stoyan
