Flex的Tree的Icon问题，求各位帮忙看看啊，谢谢了

[cmc0117]

我的代码是这样的，但是那个tree 的ItemIcon属性设置后没看到任何效果，图片路径是对的，不知道什么问题，运行后还是系统默认的那套Icon，求各位看看解决一下了，谢谢了！

楼主说的系统默认图标指什么？？

打开关闭时的图标吗，方法很多

1.用folderOpenIcon,folderCloseIcon

2.setItemIcon(item,iconClass,iconClass)

....

[chinazhousheng]

建议用Css控制
LayerTree{
selectionColor: #417597;
folderOpenIcon: Embed(source="1.png");
folderClosedIcon: Embed(source="2.png");
defaultLeafIcon: Embed(source="3.gif");
}

改成这样：
<mx:Tree x="59" y="46" width="220" height="456" id="tree1"
dataProvider="{xmlSource}"
labelField="@label" showRoot="false" disclosureClosedIcon="{itemIcon}" disclosureOpenIcon="{imgCls}" ></mx:Tree>

disclosureClosedIcon 节点的关闭
disclosureOpenIcon 节点的打开
defaultLeafIcon 叶子的默认图标

[passself]

.LayerTree{ 
selectionColor: #417597; 
folderOpenIcon: Embed(source="1.png"); 
folderClosedIcon: Embed(source="2.png"); 
defaultLeafIcon: Embed(source="3.gif"); 
}

这样就比较不错
