第一问： 如何在FLEX中做竖式导航？

答： <mx:ButtonBar direction="vertical" > </mx:ButtonBar>

 direction="horizontal" 横          direction="vertical" 竖

第二问：ToggleButtonBar时鼠标怎么变手形？

答： useHandCursor="true"

第三问：如何做一个矩形二个角圆二个角方？

答：CustomBorder.as
package
{

import mx.skins.RectangularBorder;
import flash.display.Graphics;
import mx.graphics.RectangularDropShadow;

public class CustomBorder extends RectangularBorder
{

private var dropShadow:RectangularDropShadow;

override protected function updateDisplayList
(unscaledWidth:Number, unscaledHeight:Number):void
{

super.updateDisplayList(unscaledWidth, unscaledHeight);
var cornerRadius:Number = getStyle("cornerRadius");
var backgroundColor:int = getStyle("backgroundColor");
var backgroundAlpha:Number = getStyle("backgroundAlpha");
graphics.clear();

// Background

            drawRoundRect
(
0, 0, unscaledWidth, unscaledHeight,
{tl: 0, tr:0, bl: cornerRadius, br:  cornerRadius},
backgroundColor, backgroundAlpha
);

// Shadow

            if (!dropShadow)
dropShadow = new RectangularDropShadow();

dropShadow.distance = 8;
dropShadow.angle = 45;
dropShadow.color = 0;
dropShadow.alpha = 0.4;
dropShadow.tlRadius = 0;
dropShadow.trRadius = 0;
dropShadow.blRadius = cornerRadius;
dropShadow.brRadius = cornerRadius;

dropShadow.drawShadow(graphics, 0, 0, unscaledWidth, unscaledHeight);
}

}
}

        borderSkin="CustomBorder"   MXML文件中这样

第三问：关于一些朋友问到如何通过CSS平铺背景.

答：background-image: Embed("图形", scaleGridTop="1", scaleGridBottom="2", scaleGridLeft="3", scaleGridRight="4");
backgroundSize:"100%";
注意：TOP>BOTTOM    LEFT>RIGHT
通过这个就可以实现各种需要的背景。微妙之处就在于如果针对图形设置top bottom left right的值。
