flash组件样式的改变

用CellRenderer 来改变一些组件的样式下面是改变字体 ，可以接着扩展

package style{
import fl.controls.listClasses.CellRenderer;
import fl.controls.listClasses.ICellRenderer;
import flash.text.TextFormat;
//常规
public class CellStyle1 extends CellRenderer implements ICellRenderer {

   public function CellStyle1():void {
    super();
   }

   override protected function drawBackground():void {
    var format:TextFormat = new TextFormat();

    format.color=0x000000;
    format.size=12;
    format.font="宋体";
    setStyle("textFormat",format);
    super.drawBackground();
   }
}
}

 

//

this._dataGrid为DataGrid实例
this._dataGrid.setStyle("cellRenderer",CellStyle1);//设置数据的样式为CellStyle1

为某列设置样式(这里是第一列)
this._dataGrid.getColumnAt(0).cellRenderer = CellStyle1;//设置第一列样式为CellStyle1

 

类似比如为DataGrid添加图片可以override CellRenderer 的drawLayout方法:

override protected function drawLayout():void {
   super.drawLayout();
   //trace(this.data["nick_name"]);
   if (this.numChildren>=2 && this.getChildAt(1) is TextField) {    
    this.removeChild(this.getChildAt(1));
   }
   if (this.numChildren < 2) {
    AddHeadIcon();
   }   
  }
   
  //}///end over
  
  //加载图片方法
  private function AddHeadIcon():void {
   //ShowCellIcon类根据不同的地址加载不同的图片,通过ID得到url
   var headIcon:ShowCellIcon = new ShowCellIcon(this.data["url"]);
   headIcon.name = "headIcon"+this.data["url"];   
   this.addChildAt(headIcon,this.numChildren);
   headIcon.x = this.width/3;
   headIcon.y = 0;
   //headIcon.width = 30;
   //headIcon.height = 20;
  }
