onBeforeTabClick

fires before a tab is clicked

id	number|string	the id of the tab
ev	Event	the click event object

boolean

returns false, if the event handler returns false, returns true by default

Example

tab.attachEvent("onBeforeTabClick", function(id,ev){
    //code
});

Unlike the onItemClick event this one watches clicks over separate tabs and passes the ID of a clicked tab into its handler.

You can block clicking by returning false from the event handler.
