- When the effect begins, it creates an opaque rectangle.
The rectangle floats above the target component,
its color matches the
Dissolve.color
property, and itsalpha
property is initially set to (1.0 -Dissolve.alphaFrom
). - As the effect plays, the
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 effect finishes, the rectangle is destroyed.
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.

The <mx:Dissolve>
tag
inherits the tag attributes of its superclass,
and adds the following tag attributes:
<mx:Dissolve id="ID" alphaFrom="val" alphaTo="val" color="val" />
