积少成多Flash(11) - Flex 3.0 动画效果(effect)
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
