Global Event Listener

Question

Is there any way by which I can make my button work, no matter in which scene or frame it is. Is there any way by which i can call that Event Listener to another frame for that particular instance?

for example: I have a button home_btn, I want this button to work in all scenes, without changing it's instance name. I already added an Event listener in first scene, but it doesn't work, In another frame or scene. Below is the code.

home_btn.addEventListener(MouseEvent.CLICK, process_it);

function process_it(event:MouseEvent):void
{
    nextFrame();
}

I don't know how to use dispatch event function for my button. // This only works for that particular frame.

Since you're doing this in the timeline, if you put the home_btn.addEventListener(MouseEvent.CLICK, process_it);

on the first frame of your main timeline, it will be registered even if you change to a different frame.

You can keep the function in its existing frame as that should still be called.

The reason why this works as opposed to the code being on a different frame is because frame 1 is where your timeline will start and process all the display items and code needed during this frame. That is any function, variable, or listener you want active will be running and/or stored into memory at the start of the application since it will always start on frame 1 until specified otherwise. If you have the listener on a different frame then you will have to gotoAndStop() to that frame to add the listener ( otherwise you are specifying that you don't want to add the listener until your application is at the frame ). Adding a listener to a display object on frame 1 is contingent upon the display object also being on that frame.
