To clarify, you're wanting a tabpanel with three tabs and when you click on a given tab its contents are created and all other rendered tabs' content is destroyed until you click on its tab again?

You can do a kind of lazy loading, and load only the tabs the user activate.
To do that, try the panel's activate event http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.panel.Panel-event-activate

I'm not sure how you'll destroy the tabs that aren't visible without destroying the tab, too. If the tabs are panels with items in them you could do a removeAll() on the tab once it is no longer the active tab I suppose.

Out of curiosity, why are you wanting to destroy the content in the tab once the user focuses on a different tab?
