2 labels on GoIconicNode?

GoDiagram (6 and previous)

Is there a way to add a 2nd text label on a GoIconicNode? I need one label above and one below.

Sure… but I don’t see a single sample that I can point you to. Let me go write one.

Try this:

[Serializable]
public class GoIconicNodeTwoLabel : GoIconicNode
{

public override void Initialize(ImageList imglist, int imgindex, string name)
{

<span =“Apple-tab-span” style=“white-space:pre”> base.Initialize(imglist, imgindex, name);
addTopLabel();
}

public override void Initialize(ResourceManager res, string iconname, string name)
{

<span =“Apple-tab-span” style=“white-space:pre”> base.Initialize(res, iconname, name);
addTopLabel();
}

private void addTopLabel() {
  myTopLabel = CreateLabel("top");
  this.Add(myTopLabel);
}

public override void LayoutChildren(GoObject childchanged) {
  base.LayoutChildren(childchanged);
  if (this.Initializing) return;

  GoObject icon = this.Icon;
  if (icon == null) return;

  GoText toplabel = this.TopLabel;
  if (toplabel != null) {
    toplabel.SetSpotLocation(MiddleBottom, icon, MiddleTop);

  }
}

/// <summary>
/// Make copy of the toplabel
/// </summary>
protected override void CopyChildren(GoGroup newgroup, GoCopyDictionary env) {
  base.CopyChildren(newgroup, env);
  GoIconicNodeTwoLabel newobj = (GoIconicNodeTwoLabel)newgroup;
  newobj.myTopLabel = (GoText)env[myTopLabel];
}

public virtual GoText TopLabel {
  get { return myTopLabel; }
  set {
    GoText old = myTopLabel;
    if (old != value) {
      if (old != null)
        Remove(old);
      myTopLabel = value;
      if (value != null)
        Add(value);
      Changed(ChangedTopLabel, 0, old, NullRect, 0, value, NullRect);
    }
  }
}

public virtual String TopText {
  get {
    GoText lab = this.TopLabel;
    if (lab != null)
      return lab.Text;
    else
      return "";
  }
  set {
    GoText lab = this.TopLabel;
    if (lab != null)
      lab.Text = value;
  }
}

public const int ChangedTopLabel = LastChangedHint + 1;

private GoText myTopLabel;

}

Thanks Jake. I will give it a try.

Works perfectly! Thanks!
