hi...everybody

Now I try to add a new button to the toolbar (actually I have: New,Delete & Search)
I need a "back" button, the help says this:

------------------
function addToolButton($toolButton)
Adds a custom tool button to main list view.
Params:
$toolButton - array(string $icon, string $function)
$icon - url of an icon
$function - javascript function or a command to be triggered
----------------------------------------

I think the code for a new button goes to; my controller file (in this case "Monedas" [Currency]) but when I used the code:

--------------Monedas.php in Controller-------------
$toolButton= array("http://latormenta.net/homes/images/edit.php","Volver");
$this->addToolButton($toolButton);

-Volver is a Javascript function, in my scripts directory in web.


Can you have an example more complete????

Tnks in Advance.
