mxml中动态生成组件的OO重写

参考我前面的文章http://blog.csdn.net/rubyzhudragon/archive/2009/06/10/4257836.aspx

因为项目开始需求还不清楚，代码几乎没有遵循OO原则，今天有空重写了一些代码，

这样的话无需太多的if-else了。

 

public class XComponent{

    public function reset():void{}
    public function getVal():String{
       return "";
    } 
    public function getVo():IdNameVo{

       return null;
    }   

}

 

public class XTextInput extends XComponent
 {
  public var idname:String;  
  public var t:TextInput;
  public var validator:Validator;  
  public function XTextInput(idname:String,len:int,val:String)
  {
   t=new IextInput();
   this.idname=idname;     
   init(idname,len,val);    
  }
  public function XTextInput(idname:String,len:int)
  {
   super(idname,len);
  }
  private function init(len:int,val:String):void{   
   t.id=this.idname;
   t.visible=true; 
   t.height=20;   
    if(len!=0){
    t.width=len*12;
    }   
    t.text=val;
  }
  override public function reset():void{
       t.text="";
  }
  override public function getVal():String{
   return t.text;
  } 
  override public function getVo():IdNameVo{
      if(t.text!=""){
        vo=new IdNameVo();              
     vo.name=idname;
     vo.desc=t.text;

      }
  }
