how to? - Browse Server button calls a function not popup

ive created a file browser for ckeditor.. having it open in a pop-up is messy in the extreme..

how can i tie into the click event on the browse server to rather launch the file browser in a modal etc.

basically looking at something like

config.filebrowserClick = function(){
// do stuff here that happens when the button gets clicked
}

heeeeeeelp
