The call back/listener function passes the event as a default parameter (giving you access to its properties, like x, and y of click etc.), if you want extend your function to pass additional arguments, you are free to do so.
I'm not entirely certain of the necessary syntax in the listener statement, since I usually inline my listener functions and rely on scoped variables for passing data back and forth instead of passing arguments. This doesn't necessarily make for the most portable code, but as of yet it's not been much of an issue. --- In [email protected], "bhaq1972" <[EMAIL PROTECTED]> wrote: > > Thanks for the link.
