    /// [`HeaderBar`][crate::HeaderBar] is similar to [`gtk::HeaderBar`][crate::gtk::HeaderBar], but provides additional
    /// features compared to it. Refer to [`gtk::HeaderBar`][crate::gtk::HeaderBar] for details. It is typically
    /// used as a top bar within [`ToolbarView`][crate::ToolbarView].
    ///
    /// ## Dialog Integration
    ///
    /// When placed inside an [`Dialog`][crate::Dialog], [`HeaderBar`][crate::HeaderBar] will display the dialog
    /// title instead of window title. It will also adjust the decoration layout to
    /// ensure it always has a close button and nothing else. Set
    /// [`show-start-title-buttons`][struct@crate::HeaderBar#show-start-title-buttons] and
    /// [`show-end-title-buttons`][struct@crate::HeaderBar#show-end-title-buttons] to `FALSE` to remove it if it's
    /// unwanted.
    ///
    /// ## Navigation View Integration
    ///
    /// When placed inside an [`NavigationPage`][crate::NavigationPage], [`HeaderBar`][crate::HeaderBar] will display the
    /// page title instead of window title.
    ///
    /// When used together with [`NavigationView`][crate::NavigationView] or [`NavigationSplitView`][crate::NavigationSplitView],
    /// it will also display a back button that can be used to go back to the previous
    /// page. The button also has a context menu, allowing to pop multiple pages at
    /// once, potentially across multiple navigation views.
    ///
    /// Set [`show-back-button`][struct@crate::HeaderBar#show-back-button] to `FALSE` to disable this behavior
    /// in rare scenarios where it's unwanted.
    ///
    /// ## Split View Integration
    ///
    /// When placed inside [`NavigationSplitView`][crate::NavigationSplitView] or [`OverlaySplitView`][crate::OverlaySplitView],
    /// [`HeaderBar`][crate::HeaderBar] will automatically hide the title buttons other than at the
    /// edges of the window.
    ///
    /// ## Bottom Sheet Integration
    ///
    /// When played inside [`BottomSheet`][crate::BottomSheet], [`HeaderBar`][crate::HeaderBar] will not show the title
    /// unless [`show-drag-handle`][struct@crate::BottomSheet#show-drag-handle] is set to `FALSE`, regardless
    /// of [`show-title`][struct@crate::HeaderBar#show-title]. This only applies to the default title,
    /// titles set with [`title-widget`][struct@crate::HeaderBar#title-widget] will still be shown.
    ///
    /// ## Centering Policy
    ///
    /// [`centering-policy`][struct@crate::HeaderBar#centering-policy] allows to enforce strict centering of
    /// the title widget. This can be useful for entries inside [`Clamp`][crate::Clamp].
    ///
    /// ## Title Buttons
    ///
    /// Unlike [`gtk::HeaderBar`][crate::gtk::HeaderBar], [`HeaderBar`][crate::HeaderBar] allows to toggle title button

    /// [`show-start-title-buttons`][struct@crate::HeaderBar#show-start-title-buttons] and
    /// [`show-end-title-buttons`][struct@crate::HeaderBar#show-end-title-buttons] properties.
