  /**
   * A window showing information about the application.
   *
   * <picture>
   *   <source srcset="about-window-dark.png" media="(prefers-color-scheme: dark)">
   *   <img src="about-window.png" alt="about-window">
   * </picture>
   *
   * An about window is typically opened when the user activates the `About …`
   * item in the application's primary menu. All parts of the window are optional.
   *
   * ## Main page
   *
   * `AdwAboutWindow` prominently displays the application's icon, name, developer
   * name and version. They can be set with the [property`AboutWindow:`application-icon],
   * [property`AboutWindow:`application-name],
   * [property`AboutWindow:`developer-name] and [property`AboutWindow:`version]
   * respectively.
   *
   * ## What's New
   *
   * `AdwAboutWindow` provides a way for applications to display their release
   * notes, set with the [property`AboutWindow:`release-notes] property.
   *
   * Release notes are formatted the same way as
   * [AppStream descriptions](https://freedesktop.org/software/appstream/docs/chap-Metadata.html#tag-description).
   *
   * The supported formatting options are:
   *
   * * Paragraph (`<p>`)
   * * Ordered list (`<ol>`), with list items (`<li>`)
   * * Unordered list (`<ul>`), with list items (`<li>`)
   *
   * Within paragraphs and list items, emphasis (`<em>`) and inline code
   * (`<code>`) text styles are supported. The emphasis is rendered in italic,
   * while inline code is shown in a monospaced font.
   *
   * Any text outside paragraphs or list items is ignored.
   *
   * Nested lists are not supported.
   *
   * Only one version can be shown at a time. By default, the displayed version
   * number matches [property`AboutWindow:`version]. Use
   * [property`AboutWindow:`release-notes-version] to override it.
   *
   * ## Details
   *
   * The Details page displays the application comments and links.
   *
   * The comments can be set with the [property`AboutWindow:`comments] property.
   * Unlike [property`Gtk`.AboutDialog:comments], this string can be long and
   * detailed. It can also contain links and Pango markup.
   *
   * To set the application website, use [property`AboutWindow:`website].
   * To add extra links below the website, use [method`AboutWindow`.add_link].
   *
   * If the Details page doesn't have any other content besides website, the
   * website will be displayed on the main page instead.
   *
   * ## Troubleshooting
   *
   * `AdwAboutWindow` displays the following two links on the main page:
   *
   * * Support Questions, set with the [property`AboutWindow:`support-url] property,
   * * Report an Issue, set with the [property`AboutWindow:`issue-url] property.
   *
   * Additionally, applications can provide debugging information. It will be
   * shown separately on the Troubleshooting page. Use the
   * [property`AboutWindow:`debug-info] property to specify it.
   *
   * It's intended to be attached to issue reports when reporting issues against
   * the application. As such, it cannot contain markup or links.
   *
   * `AdwAboutWindow` provides a quick way to save debug information to a file.
   * When saving, [property`AboutWindow:`debug-info-filename] would be used as
   * the suggested filename.
   *
   * ## Credits and Acknowledgements
   *
   * The Credits page has the following default sections:
   *
   * * Developers, set with the [property`AboutWindow:`developers] property,
   * * Designers, set with the [property`AboutWindow:`designers] property,
   * * Artists, set with the [property`AboutWindow:`artists] property,
   * * Documenters, set with the [property`AboutWindow:`documenters] property,
   * * Translators, set with the [property`AboutWindow:`translator-credits] property.
   *
   * When setting translator credits, use the strings `"translator-credits"` or
   * `"translator_credits"` and mark them as translatable.
   *
   * The default sections that don't contain any names won't be displayed.
   *
   * The Credits page can also contain an arbitrary number of extra sections below
   * the default ones. Use [method`AboutWindow`.add_credit_section] to add them.
   *
   * The Acknowledgements page can be used to acknowledge additional people and
   * organizations for their non-development contributions. Use
   * [method`AboutWindow`.add_acknowledgement_section] to add sections to it. For
   * example, it can be used to list backers in a crowdfunded project or to give
   * special thanks.
   *
   * Each of the people or organizations can have an email address or a website
   * specified. To add a email address, use a string like
   * `Edgar Allan Poe <edgar`poe`.com>`. To specify a website with a title, use a
   * string like `The GNOME Project https://www.gnome.org`:
   *
   * <picture>
   *   <source srcset="about-window-credits-dark.png" media="(prefers-color-scheme: dark)">
   *   <img src="about-window-credits.png" alt="about-window-credits">
   * </picture>
   *
   * ## Legal
   *
   * The Legal page displays the copyright and licensing information for the
   * application and other modules.
   *
   * The copyright string is set with the [property`AboutWindow:`copyright]
   * property and should be a short string of one or two lines, for example:
   * `© 2022 Example`.
   *
   * Licensing information can be quickly set from a list of known licenses with
   * the [property`AboutWindow:`license-type] property. If the application's
   * license is not in the list, [property`AboutWindow:`license] can be used
   * instead.
   *
   * To add information about other modules, such as application dependencies or
   * data, use [method`AboutWindow`.add_legal_section].
   *
   * ## Constructing
   *
   * To make constructing an `AdwAboutWindow` as convenient as possible, you can
   * use the function [func`show_about_window]` which constructs and shows a
   * window.
   *
   * ```c
   * static void
   * show_about (GtkApplication *app)
   * {
   *   const char *developers[] = {
   *     "Angela Avery",
   *     NULL
   *   };
   *
   *   const char *designers[] = {
   *     "GNOME Design Team",
   *     NULL
   *   };
   *
   *   adw_show_about_window (gtk_application_get_active_window (app),
   *                          "application-name", _("Example"),
   *                          "application-icon", "org.example.App",
   *                          "version", "1.2.3",
   *                          "copyright", "© 2022 Angela Avery",
   *                          "issue-url", "https://gitlab.gnome.org/example/example/-/issues/new",
   *                          "license-type", GTK_LICENSE_GPL_3_0,
   *                          "developers", developers,
   *                          "designers", designers,
   *                          "translator-credits", _("translator-credits"),
   *                          NULL);
   * }
   * ```
   *
   * ## CSS nodes
   *
   * `AdwAboutWindow` has a main CSS node with the name `window` and the
   * style class `.about`.
   * @class

   *   <img src="action-row.png" alt="action-row">
   * </picture>
   *
   * The `AdwActionRow` widget can have a title, a subtitle and an icon. The row
   * can receive additional widgets at its end, or prefix widgets at its start.
   *
   * It is convenient to present a preference and its related actions.
   *
   * `AdwActionRow` is unactivatable by default, giving it an activatable widget
   * will automatically make it activatable, but unsetting it won't change the
   * row's activatability.
   *
   * ## AdwActionRow as GtkBuildable
   *
   * The `AdwActionRow` implementation of the [iface`Gtk`.Buildable] interface
   * supports adding a child at its end by specifying “suffix” or omitting the
   * “type” attribute of a <child> element.
   *
   * It also supports adding a child as a prefix widget by specifying “prefix” as
   * the “type” attribute of a <child> element.
   *
   * ## CSS nodes
   *
   * `AdwActionRow` has a main CSS node with name `row`.
   *
   * It contains the subnode `box.header` for its main horizontal box, and
   * `box.title` for the vertical box containing the title and subtitle labels.
   *
   * It contains subnodes `label.title` and `label.subtitle` representing
   * respectively the title label and subtitle label.

  /**
   * A base class for animations.
   *
   * `AdwAnimation` represents an animation on a widget. It has a target that
   * provides a value to animate, and a state indicating whether the
   * animation hasn't been started yet, is playing, paused or finished.
   *
   * Currently there are two concrete animation types:
   * [class`TimedAnimation]` and [class`SpringAnimation]`.
   *
   * `AdwAnimation` will automatically skip the animation if
   * [property`Animation:`widget] is unmapped, or if
   * [property`Gtk`.Settings:gtk-enable-animations] is `FALSE`.
   *
   * The [signal`Animation:`:done] signal can be used to perform an action after
   * the animation ends, for example hiding a widget after animating its
   * [property`Gtk`.Widget:opacity] to 0.
   *
   * `AdwAnimation` will be kept alive while the animation is playing. As such,
   * it's safe to create an animation, start it and immediately unref it:
   * A fire-and-forget animation:
   *
   * ```c
   * static void
   * animation_cb (double    value,
   *               MyObject *self)
   * {
   *   // Do something with `value`
   * }
   *
   * static void
   * my_object_animate (MyObject *self)
   * {
   *   AdwAnimationTarget *target =
   *     adw_callback_animation_target_new ((AdwAnimationTargetFunc) animation_cb,
   *                                        self, NULL);
   *   g_autoptr (AdwAnimation) animation =
   *     adw_timed_animation_new (widget, 0, 1, 250, target);
   *
   *   adw_animation_play (animation);
   * }
   * ```
   *
   * If there's a chance the previous animation for the same target hasn't yet
   * finished, the previous animation should be stopped first, or the existing
   * `AdwAnimation` object can be reused.

   * as required by [class`Gtk`.Application]. Therefore, any subclass of

   *
   * ## Automatic Resources
   *
   * `AdwApplication` will automatically load stylesheets located in the
   * application's resource base path (see
   * [method`Gio`.Application.set_resource_base_path], if they're present.
   *
   * They can be used to add custom styles to the application, as follows:
   *
   * - `style.css` contains styles that are always present.
   *
   * - `style-dark.css` contains styles only used when
   * [property`StyleManager:`dark] is `TRUE`.
   *
   * - `style-hc.css` contains styles used when the system high contrast
   *   preference is enabled.
   *
   * - `style-hc-dark.css` contains styles used when the system high contrast
   *   preference is enabled and [property`StyleManager:`dark] is `TRUE`.

   *
   * `AdwButtonContent` is a box-like widget with an icon and a label.
   *
   * It's intended to be used as a direct child of [class`Gtk`.Button],
   * [class`Gtk`.MenuButton] or [class`SplitButton]`, when they need to have both an
   * icon and a label, as follows:
   *
   * ```xml
   * <object class="GtkButton">
   *   <property name="child">
   *     <object class="AdwButtonContent">
   *       <property name="icon-name">document-open-symbolic</property>
   *       <property name="label" translatable="yes">_Open</property>
   *       <property name="use-underline">True</property>
   *     </object>
   *   </property>
   * </object>
   * ```
   *
   * `AdwButtonContent` handles style classes and connecting the mnemonic to the
   * button automatically.
   *
   * ## CSS nodes
   *
   * ```
   * buttoncontent
   * ├── image
   * ╰── label
   * ```
   *
   * `AdwButtonContent`'s CSS node is called `buttoncontent`. It contains the
   * subnodes `image` and `label`.
   *
   * When inside a `GtkButton` or `AdwSplitButton`, the button will receive the
   * `.image-text-button` style class. When inside a `GtkMenuButton`, the
   * internal `GtkButton` will receive it instead.
   *
   * ## Accessibility
   *
   * `AdwButtonContent` uses the `GTK_ACCESSIBLE_ROLE_GROUP` role.

   * A [class`Gtk`.ListBoxRow] used to choose from a list of items.

   *   <img src="combo-row.png" alt="combo-row">

   *
   * The `AdwComboRow` widget allows the user to choose from a list of valid
   * choices. The row displays the selected choice. When activated, the row
   * displays a popover which allows the user to make a new choice.
   *
   * Example of an `AdwComboRow` UI definition:
   * ```xml
   * <object class="AdwComboRow">
   *   <property name="title" translatable="yes">Combo Row</property>
   *   <property name="model">
   *     <object class="GtkStringList">
   *       <items>
   *         <item translatable="yes">Foo</item>
   *         <item translatable="yes">Bar</item>
   *         <item translatable="yes">Baz</item>
   *       </items>
   *     </object>
   *   </property>
   * </object>
   * ```
   *
   * The [property`ComboRow:`selected] and [property`ComboRow:`selected-item]
   * properties can be used to keep track of the selected item and react to their
   * changes.
   *
   * `AdwComboRow` mirrors [class`Gtk`.DropDown], see that widget for details.
   *
   * `AdwComboRow` is [property`Gtk`.ListBoxRow:activatable] if a model is set.
   *
   * ## CSS nodes
   *
   * `AdwComboRow` has a main CSS node with name `row` and the `.combo` style
   * class.
   *
   * Its popover has the node named `popover` with the `.menu` style class, it
   * contains a [class`Gtk`.ScrolledWindow], which in turn contains a
   * [class`Gtk`.ListView], both are accessible via their regular nodes.
   *
   * ## Accessibility
   *
   * `AdwComboRow` uses the `GTK_ACCESSIBLE_ROLE_COMBO_BOX` role.

   * `AdwEntryRow` has a title that doubles as placeholder text. It shows an icon
   * indicating that it's editable and can receive additional widgets before or
   * after the editable part.
   *
   * If [property`EntryRow:`show-apply-button] is set to `TRUE`, `AdwEntryRow` can
   * show an apply button when editing its contents. This can be useful if
   * changing its contents can result in an expensive operation, such as network
   * activity.
   *
   * `AdwEntryRow` provides only minimal API and should be used with the
   * [iface`Gtk`.Editable] API.
   *
   * See also [class`PasswordEntryRow]`.
   *
   * ## AdwEntryRow as GtkBuildable
   *
   * The `AdwEntryRow` implementation of the [iface`Gtk`.Buildable] interface
   * supports adding a child at its end by specifying “suffix” or omitting the
   * “type” attribute of a <child> element.
   *
   * It also supports adding a child as a prefix widget by specifying “prefix” as
   * the “type” attribute of a <child> element.
   *
   * ## CSS nodes
   *
   * `AdwEntryRow` has a single CSS node with name `row` and the `.entry` style
   * class.

  /**
   * A [class`Gtk`.ListBoxRow] used to reveal widgets.
   *
   * <picture>
   *   <source srcset="expander-row-dark.png" media="(prefers-color-scheme: dark)">
   *   <img src="expander-row.png" alt="expander-row">
   * </picture>
   *
   * The `AdwExpanderRow` widget allows the user to reveal or hide widgets below
   * it. It also allows the user to enable the expansion of the row, allowing to
   * disable all that the row contains.
   *
   * ## AdwExpanderRow as GtkBuildable
   *
   * The `AdwExpanderRow` implementation of the [iface`Gtk`.Buildable] interface
   * supports adding a child as an action widget by specifying “action” as the
   * “type” attribute of a <child> element.
   *
   * It also supports adding it as a prefix widget by specifying “prefix” as the
   * “type” attribute of a <child> element.
   *
   * ## CSS nodes
   *
   * `AdwExpanderRow` has a main CSS node with name `row` and the `.expander`
   * style class. It has the `.empty` style class when it contains no children.

   *
   * The `AdwFlap` widget can display its children like a [class`Gtk`.Box] does or
   * like a [class`Gtk`.Overlay] does, according to the
   * [property`Flap:`fold-policy] value.
   *
   * `AdwFlap` has at most three children: [property`Flap:`content],
   * [property`Flap:`flap] and [property`Flap:`separator]. Content is the primary
   * child, flap is displayed next to it when unfolded, or overlays it when
   * folded. Flap can be shown or hidden by changing the
   * [property`Flap:`reveal-flap] value, as well as via swipe gestures if
   * [property`Flap:`swipe-to-open] and/or [property`Flap:`swipe-to-close] are set
   * to `TRUE`.
   *
   * Optionally, a separator can be provided, which would be displayed between
   * the content and the flap when there's no shadow to separate them, depending
   * on the transition type.
   *
   * [property`Flap:`flap] is transparent by default; add the
   * [`.background`](style-classes.html#background) style class to it if this is
   * unwanted.
   *
   * If [property`Flap:`modal] is set to `TRUE`, content becomes completely
   * inaccessible when the flap is revealed while folded.
   *
   * The position of the flap and separator children relative to the content is
   * determined by orientation, as well as the [property`Flap:`flap-position]
   * value.
   *
   * Folding the flap will automatically hide the flap widget, and unfolding it
   * will automatically reveal it. If this behavior is not desired, the
   * [property`Flap:`locked] property can be used to override it.
   *
   * Common use cases include sidebars, header bars that need to be able to
   * overlap the window content (for example, in fullscreen mode) and bottom
   * sheets.
   *
   * ## AdwFlap as GtkBuildable
   *
   * The `AdwFlap` implementation of the [iface`Gtk`.Buildable] interface supports
   * setting the flap child by specifying “flap” as the “type” attribute of a
   * `<child>` element, and separator by specifying “separator”. Specifying
   * “content” child type or omitting it results in setting the content child.
   *
   * ## CSS nodes
   *
   * `AdwFlap` has a single CSS node with name `flap`. The node will get the style
   * classes `.folded` when it is folded, and `.unfolded` when it's not.

   * `AdwHeaderBar` is similar to [class`Gtk`.HeaderBar], but provides additional

   *
   * [property`HeaderBar:`centering-policy] allows to enforce strict centering of

   *
   * [property`HeaderBar:`show-start-title-buttons] and

   *
   * The `AdwLeaflet` widget can display its children like a [class`Gtk`.Box] does
   * or like a [class`Gtk`.Stack] does, adapting to size changes by switching
   * between the two modes.
   *
   * When there is enough space the children are displayed side by side, otherwise
   * only one is displayed and the leaflet is said to be “folded”.
   * The threshold is dictated by the preferred minimum sizes of the children.
   * When a leaflet is folded, the children can be navigated using swipe gestures.
   *
   * The “over” and “under” transition types stack the children one on top of the
   * other, while the “slide” transition puts the children side by side. While
   * navigating to a child on the side or below can be performed by swiping the
   * current child away, navigating to an upper child requires dragging it from
   * the edge where it resides. This doesn't affect non-dragging swipes.
   *
   * ## CSS nodes
   *
   * `AdwLeaflet` has a single CSS node with name `leaflet`. The node will get the
   * style classes `.folded` when it is folded, `.unfolded` when it's not, or none
   * if it hasn't computed its fold yet.

  /**
   * A dialog presenting a message or a question.
   *
   * <picture>
   *   <source srcset="message-dialog-dark.png" media="(prefers-color-scheme: dark)">
   *   <img src="message-dialog.png" alt="message-dialog">
   * </picture>
   *
   * Message dialogs have a heading, a body, an optional child widget, and one or
   * multiple responses, each presented as a button.
   *
   * Each response has a unique string ID, and a button label. Additionally, each
   * response can be enabled or disabled, and can have a suggested or destructive
   * appearance.
   *
   * When one of the responses is activated, or the dialog is closed, the
   * [signal`MessageDialog:`:response] signal will be emitted. This signal is
   * detailed, and the detail, as well as the `response` parameter will be set to
   * the ID of the activated response, or to the value of the
   * [property`MessageDialog:`close-response] property if the dialog had been
   * closed without activating any of the responses.
   *
   * Response buttons can be presented horizontally or vertically depending on
   * available space.
   *
   * When a response is activated, `AdwMessageDialog` is closed automatically.
   *
   * An example of using a message dialog:
   *
   * ```c
   * GtkWidget *dialog;
   *
   * dialog = adw_message_dialog_new (parent, _("Replace File?"), NULL);
   *
   * adw_message_dialog_format_body (ADW_MESSAGE_DIALOG (dialog),
   *                                 _("A file named “%s” already exists. Do you want to replace it?"),
   *                                 filename);
   *
   * adw_message_dialog_add_responses (ADW_MESSAGE_DIALOG (dialog),
   *                                   "cancel",  _("_Cancel"),
   *                                   "replace", _("_Replace"),
   *                                   NULL);
   *
   * adw_message_dialog_set_response_appearance (ADW_MESSAGE_DIALOG (dialog), "replace", ADW_RESPONSE_DESTRUCTIVE);
   *
   * adw_message_dialog_set_default_response (ADW_MESSAGE_DIALOG (dialog), "cancel");
   * adw_message_dialog_set_close_response (ADW_MESSAGE_DIALOG (dialog), "cancel");
   *
   * g_signal_connect (dialog, "response", G_CALLBACK (response_cb), self);
   *
   * gtk_window_present (GTK_WINDOW (dialog));
   * ```
   *
   * ## AdwMessageDialog as GtkBuildable
   *
   * `AdwMessageDialog` supports adding responses in UI definitions by via the
   * `<responses>` element that may contain multiple `<response>` elements, each
   * respresenting a response.
   *
   * Each of the `<response>` elements must have the `id` attribute specifying the
   * response ID. The contents of the element are used as the response label.
   *
   * Response labels can be translated with the usual `translatable`, `context`
   * and `comments` attributes.
   *
   * The `<response>` elements can also have `enabled` and/or `appearance`
   * attributes. See [method`MessageDialog`.set_response_enabled] and
   * [method`MessageDialog`.set_response_appearance] for details.
   *
   * Example of an `AdwMessageDialog` UI definition:
   *
   * ```xml
   * <object class="AdwMessageDialog" id="dialog">
   *   <property name="heading" translatable="yes">Save Changes?</property>
   *   <property name="body" translatable="yes">Open documents contain unsaved changes. Changes which are not saved will be permanently lost.</property>
   *   <property name="default-response">save</property>
   *   <property name="close-response">cancel</property>
   *   <signal name="response" handler="response_cb"/>
   *   <responses>
   *     <response id="cancel" translatable="yes">_Cancel</response>
   *     <response id="discard" translatable="yes" appearance="destructive">_Discard</response>
   *     <response id="save" translatable="yes" appearance="suggested" enabled="false">_Save</response>
   *   </responses>
   * </object>
   * ```
   *
   * ## Accessibility
   *
   * `AdwMessageDialog` uses the `GTK_ACCESSIBLE_ROLE_DIALOG` role.
   * @class

   *
   * An `AdwPreferencesGroup` represents a group or tightly related preferences,
   * which in turn are represented by [class`PreferencesRow]`.
   *
   * To summarize the role of the preferences it gathers, a group can have both a
   * title and a description. The title will be used by [class`PreferencesWindow]`
   * to let the user look for a preference.
   *
   * ## AdwPreferencesGroup as GtkBuildable
   *
   * The `AdwPreferencesGroup` implementation of the [iface`Gtk`.Buildable] interface
   * supports adding [class`PreferencesRow]`s to the list by omitting "type". If "type"
   * is omitted and the widget isn't a [class`PreferencesRow]` the child is added to
   * a box below the list.
   *
   * When the "type" attribute of a child is `header-suffix`, the child
   * is set as the suffix on the end of the title and description.
   *
   * ## CSS nodes
   *
   * `AdwPreferencesGroup` has a single CSS node with name `preferencesgroup`.
   *
   * ## Accessibility
   *
   * `AdwPreferencesGroup` uses the `GTK_ACCESSIBLE_ROLE_GROUP` role.

   * `AdwSplitButton` is typically used to present a set of actions in a menu,
   * but allow access to one of them with a single click.
   *
   * The API is very similar to [class`Gtk`.Button] and [class`Gtk`.MenuButton], see
   * their documentation for details.
   *
   * ## CSS nodes
   *
   * ```
   * splitbutton[.image-button][.text-button]
   * ├── button
   * │   ╰── <content>
   * ├── separator
   * ╰── menubutton
   *     ╰── button.toggle
   *         ╰── arrow
   * ```
   *
   * `AdwSplitButton`'s CSS node is called `splitbutton`. It contains the css
   * nodes: `button`, `separator`, `menubutton`. See [class`Gtk`.MenuButton]
   * documentation for the `menubutton` contents.
   *
   * The main CSS node will contain the `.image-button` or `.text-button` style
   * classes matching the button contents. The nested button nodes will never
   * contain them.
   *
   * ## Accessibility
   *
   * `AdwSplitButton` uses the `GTK_ACCESSIBLE_ROLE_GROUP` role.

  /**
   * A spring-based [class`Animation]`.
   *
   * `AdwSpringAnimation` implements an animation driven by a physical model of a
   * spring described by [struct`SpringParams]`, with a resting position in
   * [property`SpringAnimation:`value-to], stretched to
   * [property`SpringAnimation:`value-from].
   *
   * Since the animation is physically simulated, spring animations don't have a
   * fixed duration. The animation will stop when the simulated spring comes to a
   * rest - when the amplitude of the oscillations becomes smaller than
   * [property`SpringAnimation:`epsilon], or immediately when it reaches
   * [property`SpringAnimation:`value-to] if
   * [property`SpringAnimation:`clamp] is set to `TRUE`. The estimated duration can
   * be obtained with [property`SpringAnimation:`estimated-duration].
   *
   * Due to the nature of spring-driven motion the animation can overshoot
   * [property`SpringAnimation:`value-to] before coming to a rest. Whether the
   * animation will overshoot or not depends on the damping ratio of the spring.
   * See [struct`SpringParams]` for more information about specific damping ratio
   * values.
   *
   * If [property`SpringAnimation:`clamp] is `TRUE`, the animation will abruptly
   * end as soon as it reaches the final value, preventing overshooting.
   *
   * Animations can have an initial velocity value, set via
   * [property`SpringAnimation:`initial-velocity], which adjusts the curve without
   * changing the duration. This makes spring animations useful for deceleration
   * at the end of gestures.
   *
   * If the initial and final values are equal, and the initial velocity is not 0,
   * the animation value will bounce and return to its resting position.

  /**
   * A dynamic tabbed container.
   *
   * `AdwTabView` is a container which shows one child at a time. While it
   * provides keyboard shortcuts for switching between pages, it does not provide
   * a visible tab bar and relies on external widgets for that, such as
   * [class`TabBar]`.
   *
   * `AdwTabView` maintains a [class`TabPage]` object for each page, which holds
   * additional per-page properties. You can obtain the `AdwTabPage` for a page
   * with [method`TabView`.get_page], and as the return value for
   * [method`TabView`.append] and other functions for adding children.
   *
   * `AdwTabView` only aims to be useful for dynamic tabs in multi-window
   * document-based applications, such as web browsers, file managers, text
   * editors or terminals. It does not aim to replace [class`Gtk`.Notebook] for use
   * cases such as tabbed dialogs.
   *
   * As such, it does not support disabling page reordering or detaching.
   *
   * `AdwTabView` adds a number of global page switching and reordering shortcuts.
   * The [property`TabView:`shortcuts] property can be used to manage them.
   *
   * See [flags`TabViewShortcuts]` for the list of the available shortcuts. All of
   * the shortcuts are enabled by default.
   *
   * [method`TabView`.add_shortcuts] and [method`TabView`.remove_shortcuts] can be
   * used to manage shortcuts in a convenient way, for example:
   *
   * ```c
   * adw_tab_view_remove_shortcuts (view, ADW_TAB_VIEW_SHORTCUT_CONTROL_HOME |
   *                                      ADW_TAB_VIEW_SHORTCUT_CONTROL_END);
   * ```
   *
   * ## CSS nodes
   *
   * `AdwTabView` has a main CSS node with the name `tabview`.

  /**
   * A helper object for [class`ToastOverlay]`.
   *
   * Toasts are meant to be passed into [method`ToastOverlay`.add_toast] as
   * follows:
   *
   * ```c
   * adw_toast_overlay_add_toast (overlay, adw_toast_new (_("Simple Toast")));
   * ```
   *
   * <picture>
   *   <source srcset="toast-simple-dark.png" media="(prefers-color-scheme: dark)">
   *   <img src="toast-simple.png" alt="toast-simple">
   * </picture>
   *
   * Toasts always have a close button. They emit the [signal`Toast:`:dismissed]
   * signal when disappearing.
   *
   * [property`Toast:`timeout] determines how long the toast stays on screen, while
   * [property`Toast:`priority] determines how it behaves if another toast is
   * already being displayed.
   *
   * [property`Toast:`custom-title] can be used to replace the title label with a
   * custom widget.
   *
   * ## Actions
   *
   * Toasts can have one button on them, with a label and an attached
   * [iface`Gio`.Action].
   *
   * ```c
   * AdwToast *toast = adw_toast_new (_("Toast with Action"));
   *
   * adw_toast_set_button_label (toast, _("_Example"));
   * adw_toast_set_action_name (toast, "win.example");
   *
   * adw_toast_overlay_add_toast (overlay, toast);
   * ```
   *
   * <picture>
   *   <source srcset="toast-action-dark.png" media="(prefers-color-scheme: dark)">
   *   <img src="toast-action.png" alt="toast-action">
   * </picture>
   *
   * ## Modifying toasts
   *
   * Toasts can be modified after they have been shown. For this, an `AdwToast`
   * reference must be kept around while the toast is visible.
   *
   * A common use case for this is using toasts as undo prompts that stack with
   * each other, allowing to batch undo the last deleted items:
   *
   * ```c
   *
   * static void
   * toast_undo_cb (GtkWidget  *sender,
   *                const char *action,
   *                GVariant   *param)
   * {
   *   // Undo the deletion
   * }
   *
   * static void
   * dismissed_cb (MyWindow *self)
   * {
   *   self->undo_toast = NULL;
   *
   *   // Permanently delete the items
   * }
   *
   * static void

   *              MyItem   *item)
   * {
   *   g_autofree char *title = NULL;
   *   int n_items;
   *
   *   // Mark the item as waiting for deletion
   *   n_items = ... // The number of waiting items
   *
   *   if (!self->undo_toast) {
   *     self->undo_toast = adw_toast_new_format (_("‘%s’ deleted"), ...);
   *
   *     adw_toast_set_priority (self->undo_toast, ADW_TOAST_PRIORITY_HIGH);

   *
   * Much like [class`Gtk`.Overlay], `AdwToastOverlay` is a container with a single
   * main child, on top of which it can display a [class`Toast]`, overlaid.
   * Toasts can be shown with [method`ToastOverlay`.add_toast].
   *
   * See [class`Toast]` for details.
   *
   * ## CSS nodes
   *
   * ```
   * toastoverlay
   * ├── [child]
   * ├── toast
   * ┊   ├── widget
   * ┊   │   ├── [label.heading]
   *     │   ╰── [custom title]
   *     ├── [button]
   *     ╰── button.circular.flat
   * ```
   *
   * `AdwToastOverlay`'s CSS node is called `toastoverlay`. It contains the child,
   * as well as zero or more `toast` subnodes.
   *
   * Each of the `toast` nodes contains a `widget` subnode, optionally a `button`
   * subnode, and another `button` subnode with `.circular` and `.flat` style
   * classes.
   *
   * The `widget` subnode contains a `label` subnode with the `.heading` style
   * class, or a custom widget provided by the application.
   *
   * ## Accessibility
   *
   * `AdwToastOverlay` uses the `GTK_ACCESSIBLE_ROLE_TAB_GROUP` role.

  /**
   * A view container for [class`ViewSwitcher]`.
   *
   * `AdwViewStack` is a container which only shows one page at a time.
   * It is typically used to hold an application's main views.
   *
   * It doesn't provide a way to transition between pages.
   * Instead, a separate widget such as [class`ViewSwitcher]` can be used with
   * `AdwViewStack` to provide this functionality.
   *
   * `AdwViewStack` pages can have a title, an icon, an attention request, and a
   * numbered badge that [class`ViewSwitcher]` will use to let users identify which
   * page is which. Set them using the [property`ViewStackPage:`title],
   * [property`ViewStackPage:`icon-name],
   * [property`ViewStackPage:`needs-attention], and
   * [property`ViewStackPage:`badge-number] properties.
   *
   * Unlike [class`Gtk`.Stack], transitions between views are not animated.
   *
   * `AdwViewStack` maintains a [class`ViewStackPage]` object for each added child,
   * which holds additional per-child properties. You obtain the
   * [class`ViewStackPage]` for a child with [method`ViewStack`.get_page] and you
   * can obtain a [iface`Gtk`.SelectionModel] containing all the pages with
   * [method`ViewStack`.get_pages].
   *
   * ## AdwViewStack as GtkBuildable
   *
   * To set child-specific properties in a .ui file, create
   * [class`ViewStackPage]` objects explicitly, and set the child widget as a
   * property on it:
   *
   * ```xml
   *   <object class="AdwViewStack" id="stack">
   *     <child>
   *       <object class="AdwViewStackPage">
   *         <property name="name">overview</property>
   *         <property name="title">Overview</property>
   *         <property name="child">
   *           <object class="AdwStatusPage">
   *             <property name="title">Welcome!</property>
   *           </object>
   *         </property>
   *       </object>
   *     </child>
   *   </object>
   * ```
   *
   * ## CSS nodes
   *
   * `AdwViewStack` has a single CSS node named `stack`.
   * @class

   * An adaptive view switcher designed to switch between multiple views
   * contained in a [class`ViewStack]` in a similar fashion to
   * [class`Gtk`.StackSwitcher].
   *
   * `AdwViewSwitcher` buttons always have an icon and a label. They can be
   * displayed side by side, or icon on top of the label. This can be controlled
   * via the [property`ViewSwitcher:`policy] property.
   *
   * Most applications should be using [class`ViewSwitcherBar]` and
   * [class`ViewSwitcherTitle]`.
   *
   * ## CSS nodes
   *
   * `AdwViewSwitcher` has a single CSS node with name `viewswitcher`. It can have
   * the style classes `.wide` and `.narrow`, matching its policy.
   *
   * ## Accessibility
   *
   * `AdwViewSwitcher` uses the `GTK_ACCESSIBLE_ROLE_TAB_LIST` role and uses the
   * `GTK_ACCESSIBLE_ROLE_TAB` for its buttons.

   *
   * An action bar letting you switch between multiple views contained in a
   * [class`ViewStack]`, via an [class`ViewSwitcher]`. It is designed to be put at
   * the bottom of a window and to be revealed only on really narrow windows, e.g.
   * on mobile phones. It can't be revealed if there are less than two pages.
   *
   * `AdwViewSwitcherBar` is intended to be used together with
   * [class`ViewSwitcherTitle]`.
   *
   * A common use case is to bind the [property`ViewSwitcherBar:`reveal] property
   * to [property`ViewSwitcherTitle:`title-visible] to automatically reveal the
   * view switcher bar when the title label is displayed in place of the view
   * switcher, as follows:
   *
   * ```xml
   * <object class="GtkWindow">
   *   <property name="titlebar">
   *     <object class="AdwHeaderBar">
   *       <property name="centering-policy">strict</property>
   *       <property name="title-widget">
   *         <object class="AdwViewSwitcherTitle" id="title">
   *           <property name="stack">stack</property>
   *         </object>
   *       </property>

   *       <child>
   *         <object class="AdwViewStack" id="stack"/>
   *       </child>

   * A view switcher title.

   *   <img src="view-switcher-title.png" alt="view-switcher-title">
   * </picture>
   *
   * A widget letting you switch between multiple views contained by a
   * [class`ViewStack]` via an [class`ViewSwitcher]`.
   *
   * It is designed to be used as the title widget of a [class`HeaderBar]`, and
   * will display the window's title when the window is too narrow to fit the view
   * switcher e.g. on mobile phones, or if there are less than two views.
   *
   * In order to center the title in narrow windows, the header bar should have
   * [property`HeaderBar:`centering-policy] set to
   * `ADW_CENTERING_POLICY_STRICT`.
   *
   * `AdwViewSwitcherTitle` is intended to be used together with
   * [class`ViewSwitcherBar]`.
   *
   * A common use case is to bind the [property`ViewSwitcherBar:`reveal] property
   * to [property`ViewSwitcherTitle:`title-visible] to automatically reveal the
   * view switcher bar when the title label is displayed in place of the view
   * switcher, as follows:
   *
   * ```xml
   * <object class="GtkWindow">
   *   <property name="titlebar">
   *     <object class="AdwHeaderBar">
   *       <property name="centering-policy">strict</property>
   *       <property name="title-widget">
   *         <object class="AdwViewSwitcherTitle" id="title">

   * Physical parameters of a spring for [class`SpringAnimation]`.

   * Any spring can be described by three parameters: mass, stiffness and damping.
   *
   * An undamped spring will produce an oscillatory motion which will go on
   * forever.
   *
   * The frequency and amplitude of the oscillations will be determined by the
   * stiffness (how "strong" the spring is) and its mass (how much "inertia" it
   * has).
   *
   * If damping is larger than 0, the amplitude of that oscillating motion will
   * exponientally decrease over time. If that damping is strong enough that the
   * spring can't complete a full oscillation, it's called an overdamped spring.
   *
   * If we the spring can oscillate, it's called an underdamped spring.
   *
   * The value between these two behaviors is called critical damping; a
   * critically damped spring will comes to rest in the minimum possible time
   * without producing oscillations.
   *
   * The damping can be replaced by damping ratio, which produces the following
   * springs:
   *
   * * 0: an undamped spring.
   * * Between 0 and 1: an underdamped spring.
   * * 1: a critically damped spring.
   * * Larger than 1: an overdamped spring.
