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