| Class | public class Dissolve |
| Inheritance | Dissolve  TweenEffect Effect EventDispatcher Object |
Dissolve.color property,
and its alpha property is initially set to
(1.0 - Dissolve.alphaFrom).alpha property
of the rectangle animates from (1.0 - alphaFrom)
to (1.0 - alphaTo).
As the rectangle becomes more and more opaque,
the content underneath it gradually disappears.When the target object is a Container, the Dissolve effect applies to the content area inside the container. The content area is the region where the container's background color is visible.
Note: To use the Dissolve effect with the
creationCompleteEffect trigger of a DataGrid control,
you must define the data provider of the control inline
using a child tag of the DataGrid control, or using data binding.
This issue is a result of the data provider not being set until the
creationComplete event is dispatched.
Therefore, when the effect starts playing, Flex has not completed
the sizing of the DataGrid control.

createInstance(target:Object = null):IEffectInstance
Creates a single effect instance and initializes it.
| Effect | |
|
Takes an Array of target objects and invokes the
createInstance() method on each target. | Effect | |
|
Dispatches an event into the event flow.
| EventDispatcher | |
|
end(effectInstance:IEffectInstance = null):void
Interrupts an effect that is currently playing,
and jumps immediately to the end of the effect.
| Effect | |

Returns an Array of Strings, where each String is the name
of a property that is changed by this effect.
| Effect | |
|
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event.
| EventDispatcher | |
|
pause():void
Pauses the effect until you call the
resume() method. | Effect | |
|
Begins playing the effect.
| Effect | |
|
Removes a listener from the EventDispatcher object.
| EventDispatcher | |
|
resume():void
Resumes the effect after it has been paused
by a call to the
pause() method. | Effect | |
|
reverse():void
Plays the effect in reverse, if the effect is currently playing,
starting from the current position of the effect.

| alphaFrom | property |
public var alphaFrom:NumberInitial transparency level between 0.0 and 1.0, where 0.0 means transparent and 1.0 means fully opaque.
If the effect causes the target component to disappear, the default
value is the current value of the target's alpha property.
If the effect causes the target component to appear, the default
value is 0.0.
| alphaTo | property |
public var alphaTo:NumberFinal transparency level between 0.0 and 1.0, where 0.0 means transparent and 1.0 means fully opaque.
If the effect causes the target component to disappear, the default
value is 0.0.
If the effect causes the target component to appear, the default
value is the current value of the target's alpha property.
| color | property |
public var color:uint = 0xFFFFFFFF
Hex value that represents the color of the floating rectangle
that the effect displays over the target object.
The default value is the color specified by the target component's
backgroundColor style property, or 0xFFFFFF, if
backgroundColor is not set.
| targetArea | property |
public var targetArea:RoundedRectangleThe area of the target to play the effect upon. The dissolve overlay is drawn using this property's dimensions. UIComponents create an overlay over the entire component. Containers create an overlay over their content area, but not their chrome.
The default value is null.
| Dissolve | () | constructor |
public function Dissolve(target:Object = null)Constructor.
