<!-- ##### SECTION Title ##### -->
GtkScrolledWindow

<!-- ##### SECTION Short_Description ##### -->
Adds scrollbars to its child widget

<!-- ##### SECTION Long_Description ##### -->
<para>
#GtkScrolledWindow is a #GtkBin subclass: it's a container 
the accepts a single child widget. #GtkScrolledWindow adds scrollbars
to the child widget and optionally draws a beveled frame around the 
child widget.
</para>

<para>
The scrolled window can work in two ways. Some widgets have native
scrolling support; these widgets have "slots" for #GtkAdjustment
objects. 
<footnote><para>The scrolled window installs #GtkAdjustment objects in
the child window's slots using the set_scroll_adjustments_signal,
found in #GtkWidgetClass. (Conceptually, these widgets implement a
"Scrollable" interface; because GTK+ 1.2 lacked interface support in
the object system, this interface is hackily implemented as a signal
in #GtkWidgetClass. The GTK+ 2.0 object system would allow a clean
implementation, but it wasn't worth breaking the
API.)</para></footnote>
Widgets with native scroll support include #GtkTreeView, #GtkTextView, 
and #GtkLayout.
</para>

<para>
For widgets that lack native scrolling support, the #GtkViewport
widget acts as an adaptor class, implementing scrollability for child
widgets that lack their own scrolling capabilities. Use #GtkViewport
to scroll child widgets such as #GtkTable, #GtkBox, and so on.
</para>

<para>
If a widget has native scrolling abilities, it can be added to the
#GtkScrolledWindow with gtk_container_add(). If a widget does not, you
must first add the widget to a #GtkViewport, then add the #GtkViewport
to the scrolled window. The convenience function
gtk_scrolled_window_add_with_viewport() does exactly this, so you can
ignore the presence of the viewport.
</para>

<para>
The position of the scrollbars is controlled by the scroll
adjustments. See #GtkAdjustment for the fields in an adjustment - for
#GtkScrollbar, used by #GtkScrolledWindow, the "value" field
represents the position of the scrollbar, which must be between the
"lower" field and "upper - page_size." The "page_size" field
represents the size of the visible scrollable area. The
"step_increment" and "page_increment" fields are used when the user
asks to step down (using the small stepper arrows) or page down (using
for example the PageDown key).
</para>

<para>
If a #GtkScrolledWindow doesn't behave quite as you would like, or
doesn't have exactly the right layout, it's very possible to set up
your own scrolling with #GtkScrollbar and for example a #GtkTable.
