| 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.

addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event.
| EventDispatcher | |
|
Captures the current values of the relevant properties
on the effect's targets and saves them as end values.
| Effect | |
|
Captures the current values of the relevant properties
of an additional set of targets
This function is used by Flex when a data change
effect is run.
| Effect | |
|
Captures the current values of the relevant properties
on the effect's targets.
| Effect | |
|
Creates a single effect instance and initializes it.
| Effect | |
|
Takes an Array of target objects and invokes the
createInstance() method on each target.
| Effect | |
|
Removes event listeners from an instance
and removes it from the list of instances.
| Effect | |
|
Dispatches an event into the event flow.
| EventDispatcher | |
|
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 | |

| alphaFrom | property |
public var alphaFrom:Number
Initial 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:Number
Final 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:RoundedRectangle
The 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.
