[jQuery] subclassing widgets

[Dunk Fordyce]

hello,

is it possible to subclass widgets? specifically ui.dialog?

ive tried something like the following but cant get it to work.

$.widget("ui.mydialog", $.extend($.ui.dialog, {
    init: function() {
          $.ui.dialog.prototype.init.apply(this, arguments);
          // custom stuff....
    }
}));

any hints/examples?

thanks dunk.
