flex学习笔记-布局

flex中设置图片平铺
<mx:Image source="assets/images/main.jpg" width="500" height="500" maintainAspectRatio="false" />
<s:Image source="assets/images/main.jpg" width="500" height="500" scaleMode="stretch" />

flex填充：
<s:Group includeIn="login" top="0" bottom="0" left="0" right="0">
<s:Rect width="100%" height="100%">
<s:fill>
<s:BitmapFill source="@Embed('assets/images/main.jpg')"/>
</s:fill>
</s:Rect>
</s:Group>
这里如果把embed取消掉，就不会填充任何东西，不知道什么原因？
<s:Group top="0" bottom="0" left="0" right="0">
<s:Rect width="100%" height="100%">
<s:stroke>
<s:SolidColorStroke color="0xbc276a" weight="2"/>
</s:stroke>
<s:fill>
<s:RadialGradient>
<s:entries>
<s:GradientEntry color="0xECEC21" ratio="0.66" alpha="0.5"/>
</s:entries>
</s:RadialGradient>
</s:fill>
</s:Rect>
</s:Group>

stroke表示边框
fill就是填充色了
GradientEntry中的ratio不太明白啥意思

下面是一个弹出框：
本来可以不添加group来填充颜色的，由于我重写了bordercontainer的皮肤，导致这里再设置bgcolor不起作用，还不知道什么原因？

有关重写皮肤，皮肤主要作用是来布局对应组件和设置样式，但同样也可以出发事件，这里需要注意到是，如果要扩展原有组件添加的元素的变量名称需要和皮肤中的一样
如：组件中有一个元素：
[SkinPart(required="false")]
public var btnMin:Image;
皮肤中就应该有对应的
<s:Image id="btnMin" toolTip="最小化" source="assets\images\Buttonminimize.png"
width="18" height="18" right="27" top="7"/>
类型也需要相同，而且[SkinPart(required="false")]这句话不能少，原因也不清楚，先用着吧

下面为重写的titleWindow组件，添加了最小化按钮，是项目中用到的，直接帖过来的
组件：
