public class Transition
继承Transition Inheritance Object

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

Transition 类定义了一组在响应视图状态更改时播放的效果。视图状态的定义定义了如何更改状态,而过渡则定义了在状态更改过程中可视更改发生的顺序。

要定义过渡,可将应用程序的 transitions 属性设置为 Transition 对象的数组。

可使用 Transition 类的 toStatefromState 属性来指定触发过渡的状态更改。默认情况下,fromStatetoState 属性均设置为“*”,表示将过渡应用到视图状态的任何更改。

可以使用 fromState 属性来明确指定要从中进行更改的视图状态,使用 toState 属性来明确指定要更改到的视图状态。如果状态更改和两个过渡匹配,则 toState 属性优先于 fromState 属性。如果超过一个过渡匹配,Flex 将使用过渡数组中的第一个定义。

可以使用 effect 属性来指定应用过渡时要播放的 Effect 对象。通常,它是一个包含多个效果的复合效果对象(如 Parallel 或 Sequence 效果),如下例所示:

 
  <mx:Transition id="myTransition" fromState="*" toState="*">
    <mx:Parallel>
        ...
    </mx:Parallel>
  </mx:Transition>
  

MXML 语法expanded隐藏 MXML 语法

The <mx:Transition> tag defines the following attributes:

  <mx:Transition
    Properties
    id="ID"
    effect=""
    fromState="*"
    toState="*"
    autoReverse="false"
  />

属性详细信息

autoReverse

属性
public var autoReverse:Boolean = false

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

设置为 true 以指定该过渡应用于正向和逆向视图状态更改。因此,对于从视图状态 A 到视图状态 B 的更改以及从视图状态 B 到视图状态 A 的更改,使用该过渡。

正在播放从视图状态 A 到视图状态 B 的过渡时,可以发生逆向过渡以中断当前过渡。逆向过渡总是在当前过渡的当前位置将其终止。也就是说,逆向过渡始终播放,好像 interruptionBehavior 属性已设置为 stop,而忽略 interruptionBehavior 的实际值。

仅当新过渡以与当前正在播放的过渡完全相反的方向播放时,此属性才会选中。也就是说,如果某个过渡正在状态 A 和 B 之间播放,则开始一个返回到状态 A 的过渡。

如果过渡使用 toStatefromState 属性显式处理从视图状态 B 到视图状态 A 的过渡,则 Flex 忽略 autoReverse 属性。

默认值为 false。

相关 API 元素

effect

属性 
public var effect:IEffect

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

应用过渡时要播放的 IEffect 对象。通常,它是一个包含多个效果的复合效果对象(如 Parallel 或 Sequence 效果)。

effect 属性是 Transition 类的默认属性。如果使用 MXML 标签语法,则可省略 <mx:effect> 标签。

fromState

属性 
public var fromState:String = "*"

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

该字符串指定在应用过渡时要从中进行更改的视图状态。默认值为“*”,表示任何视图状态。

可以将该属性设置为空字符串“”,它对应于基本视图状态。

默认值为 "*"。

interruptionBehavior

属性 
public var interruptionBehavior:String = "end"

语言版本: ActionScript 3.0
产品版本: Flex 4.5
运行时版本: Flash Player 10.2, AIR 2.5

Flex 不支持同时播放多个过渡。如果当前正在播放一个过渡,则发生一个新过渡时,将中断该当前过渡。该属性控制当前过渡中断时的行为方式。

默认情况下,当前过渡结束,并且过渡中的所有效果到达其结束值。这与 end 的属性值相对应。如果此属性的值为 stop,则当前过渡在其当前位置终止。新过渡从上一个过渡的终止位置开始播放。

stop 的值可以平滑中断的过渡的外观。这是因为在新过渡开始之前用户没有看到当前过渡到达其结束状态。

在某些情况下,中断过渡可以是当前过渡的逆向过渡。例如,正在播放从视图状态 A 到视图状态 B 的过渡时,发生逆向过渡以中断当前过渡。如果将过渡实例的 autoReverse 属性设置为 true,可以使用相同过渡同时处理正向和逆向过渡。如果中断过渡是当前过渡的逆向过渡,并且将 autoReverse 设置为 true,则中断过渡运行,好像 interruptionBehavior 属性已设置为 stop,而忽略 interruptionBehavior 的实际值。

mx.states.InterruptionBehavior 类定义此属性的可能值。

默认值为 end。

相关 API 元素

toState

属性 
public var toState:String = "*"

语言版本: ActionScript 3.0
产品版本: Flex 3
运行时版本: Flash Player 9, AIR 1.1

该字符串指定在应用过渡时要更改到的视图状态。默认值为“*”,表示任何视图状态。

可以将该属性设置为空字符串“”,它对应于基本视图状态。

默认值为 "*"。

[ X ]为什么显示为英语?
《ActionScript 3.0 参考》中的内容以英语显示

《ActionScript 3.0 参考》中的部分内容未翻译成所有语言。当某个语言元素未翻译时,将显示为英语。例如,ga.controls.HelpBox 类未翻译成任何语言。因此在简体中文版的参考中,ga.controls.HelpBox 类显示为英语。
