Availability
Flash Player 6 (6.0.79.0).
Edition
Flash MX Professional 2004.
Usage
listenerObject = new Object();
listenerObject.modelChanged = function(eventObject){
// Insert your code here.
}
myMenu.addEventListener("modelChanged", listenerObject)
Description
Event; broadcast to all of its view listeners whenever the data provider is modified. You
typically add a listener to a model by assigning its
dataProvider property.
Version 2 components use a dispatcher/listener event model. When a data provider changes in
some way, it broadcasts a
modelChanged event, and data-aware components catch it to update
their displays to reflect the changes in data.
