Unfortunately, double-clicking is not supported by default. If you wish to add this functionality to, say, a List or DataGrid component, you will have to add the following ActionScript 2.0 code to your application:

var someTimestamp:Number;

public function doubleClickHandler( evt:Object ):Void {

var now = getTimer();

// we got a double-click

if( ( now - someTimestamp ) < 500 ) {

// do something here ...

}

someTimestamp = now;

}
