Recieving accordion event from the "outside"

Question

hi;
i am using the accordion and need to keep track of events,
specificaly, the only thing i need right now is to know the new
currentPanelIndex of the accordion after someone clicked a panel.
what is the best way to do this?
i already tried hacking the spry.js(hacked into the openPAnel
function), it worked but i do not want to touch the JS file (so i
dont have to do this on every upgrade). i
also tried doing it from the "outside" but i could not get
it to work (after creating the accordion, i took the panels from
the accordion, looped and got the tab from each panel and used
addEventListener(tab,'click',myfunc,false) but in the first
iteration after the call to addEventListener the loop did not
continue ).
any help is appreciated.
thanks,

You can extend it from the outside by defining a function
that overrides openPanel() with a function that calls the original
openPanel() and then executes whatever code you want. The function
would look something like this:
function ExtendOpenPanel(acc)
var realFunc = acc.openPanel;
acc.openPanel = function(panel) {
realFunc.call(acc, panel);
/* Add your code or function call here! */
Then call the function after you create the widget:
var acc1 = new Spry.Widget.Accordion("acc1");
ExtendOpenPanel(acc1);
