[align=center]积少成多Flash(11) - Flex 3.0 动画效果(effect)[/align]

作者：webabcd

介绍
演示 Flex 3.0 中的各种动画效果(effect)的应用

Zoom - 放大/缩小

Wipe - 从上/下/左/右 4 个方向 线性渐变地 对控件做 删除/显示

Rotate - 旋转

Resize - 调整控件大小

Fade - 淡入/淡出

Move - 改变控件位置

Iris - 显示/消失（放射性渐变）

Blur - 模糊

Dissolve - 对控件做alpha修改

Glow - 对控件做周边发光

SoundEffect - 播放一段音频

Parallel - 对各种 effect 做并行展示

Sequence - 对各种 effect 做串行展示

TweenEffect - 此类是大部分 effect 的基类
