+* Scrolled windows do not create an automatic viewport anymore, and
+ self scrolling widgets do not provide their own scrollbars any
+ further. Self scrolling widgets of the Gtk+ core currently are
+ GtkViewport, GtkCList, GtkCTree, GtkText and GtkLayout. All of
+ these widgets can be added to a scrolled window as normal children
+ with gtk_container_add() and their scrolling abilities will be setup
+ appropriatedly in an automatic manner.
+ Widgets that do not implement own scrolling abilities but get added
+ to a scrolled window in order to have their allocations scrollable
+ inside of the scrolled window (e.g. a GtkList) have first to be added
+ to a GtkViewport, and then the viewport needs to be added to the
+ scrolled window.
+ However, the scrolled window code provides a convenience function to
+ achive this:
+ gtk_scrolled_window_add_with_viewport() which will do exactly what
+ it says, add a child widget to a viewport and put that viewport into
+ the scrolled window.
+ Scrollbar policy adjustment needs to be perfomed on the scrolled window
+ with gtk_scrolled_window_set_policy() and is not longer maintained for
+ the child widgets (e.g. GtkCList's gtk_clist_set_policy() got removed).
