/// [`ScrolledWindow`][crate::ScrolledWindow] is a container that makes its child scrollable.
///
/// It does so using either internally added scrollbars or externally
/// associated adjustments, and optionally draws a frame around the child.
///
/// Widgets with native scrolling support, i.e. those whose classes implement
/// the [`Scrollable`][crate::Scrollable] interface, are added directly. For other types
/// of widget, the class [`Viewport`][crate::Viewport] acts as an adaptor, giving
/// scrollability to other widgets. [`set_child()`][Self::set_child()]
/// intelligently accounts for whether or not the added child is a [`Scrollable`][crate::Scrollable].
/// If it isn’t, then it wraps the child in a [`Viewport`][crate::Viewport]. Therefore, you can
/// just add any child widget and not worry about the details.
///
/// If [`set_child()`][Self::set_child()] has added a [`Viewport`][crate::Viewport] for you,
/// it will be automatically removed when you unset the child.
/// Unless [`hscrollbar-policy`][struct@crate::ScrolledWindow#hscrollbar-policy] and
/// [`vscrollbar-policy`][struct@crate::ScrolledWindow#vscrollbar-policy] are [`PolicyType::Never`][crate::PolicyType::Never] or
/// [`PolicyType::External`][crate::PolicyType::External], [`ScrolledWindow`][crate::ScrolledWindow] adds internal [`Scrollbar`][crate::Scrollbar] widgets
/// around its child. The scroll position of the child, and if applicable the
/// scrollbars, is controlled by the [`hadjustment`][struct@crate::ScrolledWindow#hadjustment]
/// and [`vadjustment`][struct@crate::ScrolledWindow#vadjustment] that are associated with the
/// [`ScrolledWindow`][crate::ScrolledWindow]. See the docs on [`Scrollbar`][crate::Scrollbar] for the details,
/// but note that the “step_increment” and “page_increment” fields are only
/// effective if the policy causes scrollbars to be present.
///
/// If a [`ScrolledWindow`][crate::ScrolledWindow] 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 [`Scrollbar`][crate::Scrollbar] and for example a [`Grid`][crate::Grid].
///
/// # Touch support
///
/// [`ScrolledWindow`][crate::ScrolledWindow] has built-in support for touch devices. When a
/// touchscreen is used, swiping will move the scrolled window, and will
/// expose 'kinetic' behavior. This can be turned off with the
/// [`kinetic-scrolling`][struct@crate::ScrolledWindow#kinetic-scrolling] property if it is undesired.
///
/// [`ScrolledWindow`][crate::ScrolledWindow] also displays visual 'overshoot' indication when
/// the content is pulled beyond the end, and this situation can be
/// captured with the [`edge-overshot`][struct@crate::ScrolledWindow#edge-overshot] signal.
///
/// If no mouse device is present, the scrollbars will overlaid as
/// narrow, auto-hiding indicators over the content. If traditional
/// scrollbars are desired although no mouse is present, this behaviour
/// can be turned off with the [`overlay-scrolling`][struct@crate::ScrolledWindow#overlay-scrolling]
/// property.
///
/// # Shortcuts and Gestures
///
/// The following signals have default keybindings:
///
/// - [`scroll-child`][struct@crate::ScrolledWindow#scroll-child]
///
/// # CSS nodes
///
/// [`ScrolledWindow`][crate::ScrolledWindow] has a main CSS node with name scrolledwindow.
/// It gets a .frame style class added when [`has-frame`][struct@crate::ScrolledWindow#has-frame]
/// is [`true`].
///
/// It uses subnodes with names overshoot and undershoot to draw the overflow
/// and underflow indications. These nodes get the .left, .right, .top or .bottom
/// style class added depending on where the indication is drawn.
///
/// [`ScrolledWindow`][crate::ScrolledWindow] also sets the positional style classes (.left, .right,
/// .top, .bottom) and style classes related to overlay scrolling
/// (.overlay-indicator, .dragging, .hovering) on its scrollbars.
///
/// If both scrollbars are visible, the area where they meet is drawn
/// with a subnode named junction.
///
/// # Accessibility
///
/// Until GTK 4.10, [`ScrolledWindow`][crate::ScrolledWindow] used the `GTK_ACCESSIBLE_ROLE_GROUP` role.
///
/// Starting from GTK 4.12, [`ScrolledWindow`][crate::ScrolledWindow] uses the `GTK_ACCESSIBLE_ROLE_GENERIC` role.
