    /// [`FileFilter`][crate::FileFilter] filters files by name or mime type.
    ///
    /// [`FileFilter`][crate::FileFilter] can be used to restrict the files being shown in a
    /// [`FileChooser`][crate::FileChooser]. Files can be filtered based on their name (with
    /// [`add_pattern()`][Self::add_pattern()] or [`add_suffix()`][Self::add_suffix()])
    /// or on their mime type (with [`add_mime_type()`][Self::add_mime_type()]).
    ///
    /// Filtering by mime types handles aliasing and subclassing of mime
    /// types; e.g. a filter for text/plain also matches a file with mime
    /// type application/rtf, since application/rtf is a subclass of
    /// text/plain. Note that [`FileFilter`][crate::FileFilter] allows wildcards for the
    /// subtype of a mime type, so you can e.g. filter for image/\*.
    ///
    /// Normally, file filters are used by adding them to a [`FileChooser`][crate::FileChooser]
    /// (see [`FileChooserExt::add_filter()`][crate::prelude::FileChooserExt::add_filter()]), but it is also possible to
    /// manually use a file filter on any [`FilterListModel`][crate::FilterListModel] containing
    /// `GFileInfo` objects.
    ///
    /// # GtkFileFilter as GtkBuildable
    ///
    /// The [`FileFilter`][crate::FileFilter] implementation of the [`Buildable`][crate::Buildable] interface
    /// supports adding rules using the `<mime-types>` and `<patterns>` and
    /// `<suffixes>` elements and listing the rules within. Specifying a
    /// `<mime-type>` or `<pattern>` or `<suffix>` has the same effect as
    /// as calling
    /// [`add_mime_type()`][Self::add_mime_type()] or
    /// [`add_pattern()`][Self::add_pattern()] or
    /// [`add_suffix()`][Self::add_suffix()].
    ///
    /// An example of a UI definition fragment specifying [`FileFilter`][crate::FileFilter]
    /// rules:
    /// ```xml

    ///   <mime-types>
    ///     <mime-type>text/plain</mime-type>
