Extends the standard Starling Button by adding an id parameter. The id parameter can then be retrieved from the event dispatched to the 'onButtonTriggered' listener. (see usage example in the first comment)

Extends the standard Starling Button by adding an id parameter. The id parameter can then be retrieved from the event dispatched to the 'onButtonTriggered' listener. For example:

private function onButtonTriggered(event:Event):void 
{ 
        var button:IdButton = event.target as IdButton; 
        var buttonName:String = button.name; 
        var id:uint = button.id;

        // Perform different actions based on buttonName and id
        if (buttonName == "backButton") 
                showScreen(id); 
        else if (buttonName == "clickedLevel")  
                startLevel(id); 
}
