问题是，用官方label是没有问题的，用自己写的label就无法显示了，但是无报错，求解决~~DemoLabel类：

package
{
//	import laya.ui.Label;
	import laya.webgl.WebGL;
	
	public class DemoLabel
	{
		public function DemoLabel()
		{
			Laya.init(800, 600, WebGL);
			Laya.stage.bgColor = "#232628";

//---------------------------------这是用我自己写的label继承了官方的label，问题是label显示不出来，但是也无报错--------------------------------------------			
			var label:Label = new Label();
			var textFormat:TextFormat = new TextFormat("Microsoft YaHei", 50, "#FF00FF", true, true, true);
			label.textFormat = textFormat;
			label.wordWrap = true;
			label.lWidth = 100; 
			label.lHeight = 100;
			label.txt = "Hello";
			label.lx = 100;
			label.ly = 100;
			Laya.stage.addChild(label);

//---------------------------------这是用官方的api，无问题--------------------------------------------			
//			var label:laya.ui.Label = new laya.ui.Label();
//			label.text = "Hello";
//			label.fontSize = 50;
//			label.color = "#FF00FF";
//			label.wordWrap = true;
//			label.width = 100; 
//			label.height = 100;
//			label.x = 100;
//			label.y = 100;
//			Laya.stage.addChild(label);
		}
	}

}

自己写的label类：

package
{
	import laya.ui.Label;
	/**
	 * 继承官方的label
	 * @author Administrator
	 * 
	 */	
	public class Label extends laya.ui.Label
	{
		private var _textFormat:TextFormat;
		private var _txt:String;
		private var _lWidth:int;
		private var _lHeight:int;
		private var _lx:int;
		private var _ly:int;
		
		public function Label(text:String="")
		{
			super(text);
			
		}
		
		public function get textFormat():TextFormat
		{
			return _textFormat;
		}
		public function set textFormat(value:TextFormat):void
		{
			_textFormat = value;
			
			font = _textFormat._font;
			fontSize = _textFormat._fontSize;
			color = _textFormat._color;
			bold = _textFormat._bold;
			italic = _textFormat._italic;
			underline = _textFormat._underline;
			padding = String(_textFormat._leftMargin);
//			leftMargin = value.leftMargin;
//			rightMargin = value.rightMargin;
//			indent = value.indent;
//			leading = value.leading;
			
		}
		
		public function get txt():String
		{
			return _txt;
		}
		
		public function set txt(value:String):void
		{
			_txt = value;
			text = _txt;
		}
		
		public function get lWidth():int
		{
			return _lWidth;
		}
		
		public function set lWidth(value:int):void
		{
			_lWidth = value;
			width = _lWidth;
		}
		
		public function get lHeight():int
		{
			return _lHeight;
		}
		
		public function set lHeight(value:int):void
		{
			_lHeight = value;
			height = _lHeight;
		}
		
		public function get lx():int
		{
			return _lx;
		}
		
		public function set lx(value:int):void
		{
			_lx = value;
			x = _lx;
		}
		
		public function get ly():int
		{
			return _ly;
		}
		
		public function set ly(value:int):void
		{
			_ly = value;
			y = _ly;
			
		}
	}

}

TextFormat类：

package
{
	

	public class TextFormat
	{
		public var _font:String;
		public var _fontSize:int;
		public var _color:String;
		public var _bold:Boolean;
		public var _italic:Boolean;
		public var _underline:Boolean;
		public var _leftMargin:Object;
		public var _rightMargin:Object;
		public var _indent:Object;
		public var _leading:Object;
		
		public function TextFormat(font:String = "方正粗圆_GBK", size:int = 20, color:String = "#FFFF00", 
								   bold:Boolean = false, italic:Boolean = false, underline:Boolean = false, 
								   url:String = null, target:String = null, align:String = null, 
								   leftMargin:Object = null, rightMargin:Object = null, 
								   indent:Object = null, leading:Object = null)
		{
			//Config.fontName, 18, LIST_LABEL_COLOR, 
			//false, false, false, 
			//null, null, TextFormatAlign.LEFT, 
			//0, 0, 0, 0
			_font = font;
			_fontSize = size;
			_color = color;
			
			_bold = bold;
			_italic = italic;
			_underline = underline;
			
//			_url = url;//没用到
//			_target = target;//没用到
//			_align = align;
			
			_leftMargin = String(leftMargin);
			_rightMargin = String(rightMargin);
			_indent = String(indent);
			_leading = String(leading);
			console.log("font==="+_font, "size==="+_fontSize, "color==="+_color, "bold==="+_bold, "italic==="+_italic, 
				"underline==="+_underline,"leftMargin==="+_leftMargin, "rightMargin==="+_rightMargin);
			
		}
		
	}
