NGUITools.AddWidgetCollider doesn't work!

[xiaoniaojjj]

It's my code, after NGUITools.AddWidgetCollider(uLabel.gameObject); the gameObject didn't add the BoxCollider ,
Who can tell me why?

1. void OnClick()
2.         {              
3.                 string msg = uInputField.text;
4.                 GameObject goLabel = GameObject.Instantiate(uLabelMsgTemp) as GameObject;
5.                 UILabel uLabel = goLabel.GetComponentInChildren<UILabel>();
6.                 uLabel.text = msg;
7.                 Vector3 scale = goLabel.transform.localScale;
8.                 NGUITools.AddChild(uTextList.gameObject,goLabel);
9.                 goLabel.transform.localScale = scale;
10.                 NGUITools.AddWidgetCollider(uLabel.gameObject);
11.                 uTextList.repositionNow = true;
12.         }

You create a game object -- and you never parent it. The resulting widgets is not a part of the UI.

Use NGUITools.AddChild instead.

Also look into NGUITools.AddWidget.
