Description
I want BTabView::SetSelectionMessage() like BListView::SetSelectionMessage().
It is convenient for handling change of tab. For example, displaying help message for current tab, partiall layouting for similar view like search/replace.

These 2 files are prototype. These are lacking of at least Notify() overriding.

I thought about implementation.
If BTabView with SetSelectionMessage() is implemented normally (like BListView), BTabView inherits both BView and BInvoker. But, this way breaks binary compatibility because of FBC (Fragile Base Class) problem.
I think implementing BTabView by "has a" BInvoker won't be influenced by FBC problem. But, it is a bit trickky.
I think it is better to let this enhancement wait for after Haiku R1 (breaking binary compatibility).
