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
