MultiNodePort and XML

GoDiagram (6 and previous)

Hello,
I need a MultiNodePort in my project. So I used the MultiNodePort exemple in demo1. The MultiPortNode class is the same as in the Demo1.
This is the node class :

[code][Serializable]
public class bnode : GoIconicNode
{
public bnode(string image, string label)
{
this.Initializing = true;
this.ResizesRealtime = true;
mpn.Initialize(null, image, label);
mpn.Label.SetSpotLocation(GoObject.BottomCenter, mpn.Icon, GoObject.BottomCenter);
mpn.Icon.Size = new SizeF(103, 67);
mpn.Shadowed = true;
mpn.Resizable = true;
mpn.ResizesRealtime = true;
mpn.Label.Editable = true;
up = (MultiPortNodePort)mpn.AddPort(1, new SizeF(51, 0), GoObject.MiddleTop, 1);
up.BrushColor = Color.White;
up.IsValidFrom = false;
up.IsValidTo = true;
left = (MultiPortNodePort)mpn.AddPort(2, new SizeF(0, 33), GoObject.TopLeft, 2);
left.BrushColor = Color.White;
left.IsValidFrom = true;
left.IsValidTo = false;
right = (MultiPortNodePort)mpn.AddPort(3, new SizeF(103, 33), GoObject.TopRight, 3);
right.BrushColor = Color.White;
right.IsValidFrom = true;
right.IsValidTo = false;
this.Initializing = false;
}
public void add(GoDocument dest_doc) { dest_doc.Add(mpn); } private MultiPortNode mpn = new MultiPortNode();
private MultiPortNodePort up = null;
private MultiPortNodePort left = null;
private MultiPortNodePort right = null;
}[/code] I trying to use the RegisterTransformers function of the user guide, where I have just added that : [code] MultiPortNode mpn = new MultiPortNode();
mpn.Text = "";
mpn.Initialize(null, "", "");
GoXmlBindingTransformer bt2 = new GoXmlBindingTransformer("mynode", mpn);
bt2.HandlesNamedPorts = true;
bt2.AddBinding("SetSpotLocation", "SetSpotLocation");
bt2.AddBinding("label", "Text");
bt2.AddBinding("image", "Icon.Name");
bt2.AddBinding("iconsize", "Icon.Size");
bt2.AddBinding("Location", "Location");
rw.AddTransformer(bt2); MultiPortNodePort gnp = new MultiPortNodePort();
gnp.UserFlags = 0;
gnp.Center = new PointF();
gnp.FromSpot = 0;
gnp.ToSpot = 0;
gnp = (MultiPortNodePort)mpn.AddPort(0, new SizeF(), 0, 0);
GoXmlBindingTransformer btp = new GoXmlBindingTransformer(gnp);
btp.HandlesNamedPorts = true;
btp.IdAttributeUsedForSharedObjects = true;
btp.AddBinding("forme", "MultiPortNodePort.forme");
btp.AddBinding("Style", "Style");
btp.AddBinding("from", "FromPSpot");
btp.AddBinding("to", "ToSpot");
btp.AddBinding("Center", "Center");
btp.AddBinding("loc1", "Location");
btp.AddBinding("GoPortStyle1", "GoPortStyle");
btp.AddBinding("Center1", "Center");
btp.AddBinding("left", "LeftSide");
btp.AddBinding("name", "Name");
rw.AddTransformer(btp);[/code] But Nodes and ports are not saved in a XML database.
I try a lot of bindings without succes.
Could you help me, please?

What’s the relationship between the “bnode” class and the MultiPortNode class?

You need to make sure that the instance of the node used by a GoXmlBindingTransformer is the same class as that of the nodes that are actually in your document.
