如何在Renderer中设置属性 Renderer中设置属性的方法实例,需要的朋友可以参考一下
ClassFactory的properties妙用
1)UITextField与label,使用label显不出来
[U]复制代码[/U] 代码如下:
package com.citigroup.presentation.csa
{
import flash.events.MouseEvent;
import mx.controls.Label;
import mx.controls.advancedDataGridClasses.AdvancedDataGridHeaderRenderer;
import mx.core.UITextField;
import mx.events.FlexEvent;
public class GroupHeaderRenderer extends AdvancedDataGridHeaderRenderer
{
public var children:Array=[];
public var expand:Boolean=true;
private var l:UITextField;
public function GroupHeaderRenderer()
{
super();
l=new UITextField();
l.text="[-]";
l.addEventListener(MouseEvent.CLICK,toggle);
addChild(l);
this.addEventListener(FlexEvent.CREATION_COMPLETE,init);
}
private function init(event:FlexEvent):void{
if(expand){
l.text="[-]";
}else{
l.text="[+]";
toggleChildren(false);
}
this.removeEventListener(FlexEvent.CREATION_COMPLETE,init);
}
override public function set data(value:Object):void{
super.data = value;
this.setStyle("color","0xF9F088");
this.setStyle("fontWeight","bold");
this.setStyle("textAlign","left");
}
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{
super.updateDisplayList(unscaledWidth,unscaledHeight);
label.x=0;
l.x=label.x+label.width;
l.y=label.y;
}
private function toggle(event:MouseEvent):void{
if(l.text=="[+]"){
l.text="[-]";
toggleChildren(true);
}else{
l.text="[+]";
toggleChildren(false);
}
}
private function toggleChildren(visible:Boolean):void{
if(children.lengthvar cf:ClassFactory=new ClassFactory(GroupHeaderRenderer);
cf.properties ={'children':children,'expand':expand};
group.headerRenderer=cf;
group.children=children;
return group;
