getUpdater() method of Ext.tab.Panel in Ext JS 4.x

[jhudaverdi]

Hi all,
we were using getUpdater() method of Ext.tab.Panel in Ext JS 2.x, but by the release of ExtJs4, I do not know which method performs its job. Could you give an example please what changes has to be made in order to use getUpdater() method and transform these code to ExtJs4.1? Thanks in advance...

        var updater =tab.getUpdater();
        updater.on('beforeupdate', function (x, y, z) {/**/});
        updater.on('update', function (x, y) {/**/});
        updater.update(menu.targetUrl);
        tab.setTitle('any title');

If you're saying that you want to be able to dynamically update the contents of a Tab via a specified URL, take a look at the loader configuration on Ext.panel.Panel.
