How can I proxy multiple event types to the same event callback function?
Problem
I would like to have a single callback function that can handle callbacks for a variety of different types of events such as MouseEvent and TouchEvent.
Solution
Just use the same event listener function (or closure) for multiple event types. Instead of strictly typing the event object in the event listening function you type it as flash.events.Event which is the least common denominator in this case.
Detailed explanation
Just use the same event listener function (or closure) for multiple event types. Instead of strictly typing the event object in the event listening function you type it as flash.events.Event which is the least common denominator in this case (usually, you should always type your variables and parameters as strict as possible - but this is one of the use cases where you don't want it)
ui.addEventListener(TouchEvent.TOUCH_BEGIN, myHandler);
ui.addEventListener(MouseEvent.CLICK, myHandler);
private function eventHandler(event:Event)
{
// your code here
}
private function eventHandler(event:Event)
{
switch (event.type)
{
case TouchEvent.TOUCH_BEGIN:
// do whatever needs to be done here
break;
case MouseEvent.CLICK:
// do whatever needs to be done here
break;
}
}
