//: Adds scrollbars to its child widget.
//- {\class Gtk::ScrolledWindow} is a {Gtk::Bin::} subclass: it's a container that accepts
//- a single child widget. {\class Gtk::ScrolledWindow} adds scrollbars to the child widget.
//-
//- The scrolled window can work in two ways. Some widgets have native scrolling support;
//- these widgets have {\i slots} for {Gtk::Adjustment::} objects. The scrolled window
//- installs {Gtk::Adjustment::} objects in the child window's slots using the
//- set_scroll_adjustments_signal, found in the {Gtk::Widget::} Class. (This is how it works in GTK+, not sure about GTK--).
//-
//- The second way to use the scrolled window is useful with widgets that lack the
//- set_scroll_adjustments_signal. The {Gtk::Viewport::} widget acts as a
//- proxy, implementing scrollability for child widgets that lack their own scrolling capabilities.
//-
//- If a widget has native scrolling abilities, it can be added to the
//- {\class Gtk::ScrolledWindow} with {Gtk::Container::add()}. If a widget does not, you must first add
//- the widget to a {Gtk::Viewport::}, then add the {Gtk::Viewport::} to the scrolled
//- window. The convenience function {add_with_viewport()} does exactly this, so you can
//- ignore the presence of the viewport.

  //- never present. If {\enum GTK_POLICY_AUTOMATIC}, the scrollbar is present
  //- only if needed (that is, if the slider part of the bar would be smaller

  //- {\type GtkCornerType} are {\enum GTK_CORNER_TOP_RIGHT},
  //- {\enum GTK_CORNER_BOTTOM_LEFT}, and {\enum GTK_CORNER_BOTTOM_RIGHT}.
  //- {\var window_placement}: Position of the child window.


  void set_placement(GtkCornerType window_placement);

  //: Used to add children without native scrolling capabilities.
  //- This is simply a convenience function; it is equivalent to adding the unscrollable
  //- child to a viewport, then adding the viewport to the scrolled window. If a child
  //- has native scrolling, use {Gtk::Container::add()} instead of this function.
  //-
  //- The viewport scrolls the child by moving its {Gdk::Window::}, and takes the size
  //- of the child to be the size of its toplevel {Gdk::Window::}. This will be very
  //- wrong for most widgets that support native scrolling; for example, if you add a
  //- {Gtk::CList::} with a viewport, the whole widget will scroll, including the
  //- column headings. Thus {Gtk::CList::} supports scrolling already, and should not
  //- be used with the {Gtk::Viewport::} proxy.
