I disagree with this approach. It's unnecessary and makes code less
manageable. It's cleaner to set the argument as optional (event = null)
than write
True. But then again, if at the start you already find yourself
needing to call a function outside of the context of a mouse event,
doesnt that indicate that locking it in as such, and then finding
workarounds, might be more trouble than its worth?

mm, well guys, when it comes to a long function that handles an event, It
wouldn't be convenient to REWRITE it another time to be used manually.
Anyways, I'll give a try on that, and feedback.
Cheers and thanks for the help.

Hi,
I've got a function that is called when a listener listens an event like:

If I try to call myFunction using myFunction() , the compiler throws me an

Technically speaking, you can instantiate a bogus MouseEvent to call the
function:
myFunction(new MouseEvent(MouseEvent.CLICK));
However, I only mention this to be complete in directly answering the
question. I would think that Matt's suggestion is the more appropriate.

the handler into 2 methods, and call the 2nd
method directly when needed.

You can also just send null.
myFunction(null);

If you're not actually accessing any of the properties of the MouseEvent
in your listener function, you could do the following:
(...args)
or you could keep it strict and use
(e:MouseEvent = null)
Either works fine, though the second one is explicitly cleaner.

I agree. I can see both sides of the point--more granular encapsulation,
etc. However, in addition to creating more breadcrumbs to follow, it may not
be all that practical in every case. You may not always know you need this
and may have to deal with less manageable code more and more as the need
