flex4 给容器加背景图片

直接在在mxml容器中加入方式:

<s:Group width="100%" height="100%" visible="false">
<s:Rect width="100%" height="100%">
<s:fill>
<s:BitmapFill source="@Embed('Img/bg.png')"/>
</s:fill>
</s:Rect>
</s:Group>
 

在初始化函数代码中加入方式:

首先将图片嵌入资源中:
[Embed(source="Img/bg.png")]
[Bindable]
private var obj:Class;

再在函数中:
private function init():void
{
var bitmap:BitmapFill = new BitmapFill();
bitmap.source = obj;

var group:Group = new Group();
group.width = this.width;
group.height = this.height;
this.addElement(group);

var rect:Rect = new Rect();
rect.width = this.width;
rect.height = this.height;
rect.fill = bitmap;
group.addElement(rect);
}
