Always = 0_u32

The scrollbar is always visible. The view size is independent of the content.

Automatic = 1_u32

The scrollbar will appear and disappear as necessary. For example, when all of a Gtk::TreeView can not be seen.

Never = 2_u32

The scrollbar should never appear. In this mode the content determines the size.

Don't show a scrollbar, but don't force the size to follow the content. This can be used e.g. to make multiple scrolled windows share a scrollbar.
