How to catch Clipboard error?

when in version 3.6, i can catch Clipboard as below:
dhtmlxError.catchError(“Clipboard”, function (a, b, c)
{

})

but now dhtmlxError is disappear, how to catch Clipboard error?

Thanks!

In the latest version, dhtmlxGrid uses a different approach to clipboard operations, so it must work in all modern browsers.
There is no need for onClipboard error handler anymore.

thanks! i see.
