tabViewDidChangeNumberOfTabViewItems:
informs the delegate that the number of tab view items in the tab view has changed.
tabView:didSelectTabViewItem:
informs the delegate that the specified tab view item has been selected.
tabView:shouldSelectTabViewItem:
informs the delegate that the specified tab view item is about to be selected. The delegate can return NO
to prevent the selection.
tabView:willSelectTabViewItem:
informs the delegate that the specified tab view item will be selected. The delegate can perform tasks related to the selection, but cannot prevent it.
