西沉空间*永远的红茶

mx.skins.halo.Defaults这个类包含了flash2004组件的一些全局和个别组件的默认定义，通过对他的修改能很轻松的改变组件的行为和样式。不要紧张先看一下代码，有些加了注释：
    static function setThemeDefaults():Void
    {
        var o = _global.style;
        o.themeColor = 0x80ff4d; // "haloGreen" base color
        o.disabledColor = 0x848284;
//模式窗口的的背景透明度，如你用alert组件弹出模式窗口是的背景
        //默认为全透明
        o.modalTransparency = 0;
        //是否填充
        o.filled = true;
        //是否使用画笔
        o.stroked = true;
        //画笔宽度
        o.strokeWidth = 1;
        //画笔颜色
        o.strokeColor = 0x000000;
        //添充颜色
        o.fillColor = 0xffffff;
        //循环时间
        o.repeatInterval = 35;    // fast.
        //延时
        o.repeatDelay = 500;    // half second.
//默认字体
        o.fontFamily = "_sans";
        //字体大小
        o.fontSize = 12;
//选择项的背景颜色，在list,combobox等组件中使用
        o.selectionColor = 0xCDFFC1;
        //移动到项上时的前景色
        o.rollOverColor = 0xe3ffd6;

        o.useRollOver = true;

        o.backgroundDisabledColor = 0xdddddd;
        o.selectionDisabledColor = 0xdddddd;
        //选择动画的持续时间
        o.selectionDuration = 200;
        //打开延时
        o.openDuration = 250;
        //默认边框样式，重要！方便的修改掉难看的边框
        //边框样式有"insert","none","solid","alert"等
        o.borderStyle = "inset";
//默认字体颜色
        o.color = 0xB333C;
        //字体选择颜色
        o.textSelectedColor = 0x005f33;
        //字体over颜色
        o.textRollOverColor = 0x2b333c;
        //字体无效颜色，其实是组件无效时，里面的字体颜色
        o.textDisabledColor = 0xffffff;
//datagrid组件是否有垂直分割线
        o.vGridLines = true;
        //datagrid组件是否有水平分割线
        o.hGridLines = false;
        //分割线的颜色
        o.vGridLineColor = 0x666666;
        o.hGridLineColor = 0x666666;
        
        o.headerColor = 0xeaeaea;

//日历组件当天的颜色
        o.todayColor = 0x666666;

        // default styles for various classes. other
        // properties are set on the ListAssets symbol
        //列表项的背景颜色

不过一般的你不能直接修改代码就能得到效果，你需要FLA 文件源代码：Flash MX 2004_install_dir/en/First Run/ComponentFLA/StandardComponents.fla 文件重新生成组件，另一个方法是
把代码加在时间轴上：
_global.style.color = 0xff0000;
_global.style.selectionColor=0xeeeeee;
_global.style.rollOverColor=0xffde00;
_global.styles.ScrollSelectList.backgroundColor=0xdedede;
_global.styles.ScrollSelectList.borderColor=0x000000;
_global.styles.ComboBox.borderStyle="none"
代码是参考类文件里的定义加的，来修改combobox组件的样式。
