i learned from the book Ext-JS in action that the Panel class has (or inherits from somewhere) a config option "split" which when set to true, allows dragging of regions in a container with border layout. but the api document http://dev.sencha.com/deploy/ext-3.4.0/docs/ seems to not have included this config option. Do i got the wrong api or it's just mentioned somewhere that i overlooked? thanks.
thanks
so the point is that config objects for items of BorderLayout containers are actually (implicitly) created to be Region objects.
i think this is somewhat confusing. configuration options that are to be used by different classes are now within a single object.
