Selection.removeListener() 611
Selection.onSetFocus
Availability
Flash Player 6.
Usage
someListener.onSetFocus = function(oldFocus, newFocus){
statements;
}
Description
Listener; notified when the input focus changes. To use onSetFocus, you must create a listener
object. You can then define a function for
onSetFocus and use addListener() to register the
listener with the Selection object, as in the following:
someListener = new Object();
someListener.onSetFocus = function () { ... };
Selection.addListener(someListener);
Listeners enable different pieces of code to cooperate because multiple listeners can receive
notification about a single event.

not successfully removed, for example if the
listener was not on the Selection object’s listener
list, the method returns a value of
false.
Description
Method; removes an object previously registered with addListener().
