    /// It is possible to implement custom handling for links and their tooltips

    /// [`current_uri()`][Self::current_uri()] function.
    ///
    /// ## Properties
    ///
    ///
    /// #### `attributes`
    ///  A list of style attributes to apply to the text of the label.
    ///
    /// Readable | Writable
    ///
    ///
    /// #### `ellipsize`
    ///  The preferred place to ellipsize the string, if the label does
    /// not have enough room to display the entire string.
    ///
    /// Note that setting this property to a value other than
    /// [enum.Pango.EllipsizeMode.none] has the side-effect that the label requests
    /// only enough space to display the ellipsis "...". In particular, this
    /// means that ellipsizing labels do not work well in notebook tabs, unless
    /// the [`tab-expand`][struct@crate::NotebookPage#tab-expand] child property is set to true.
    ///
    /// Other ways to set a label's width are [`WidgetExt::set_size_request()`][crate::prelude::WidgetExt::set_size_request()]
    /// and [`Label::set_width_chars()`][crate::Label::set_width_chars()].
    ///
    /// Readable | Writable
    ///
    ///
    /// #### `extra-menu`
    ///  A menu model whose contents will be appended to the context menu.
    ///
    /// Readable | Writable
    ///
    ///
    /// #### `justify`
    ///  The alignment of the lines in the text of the label, relative to each other.
    ///
    /// This does *not* affect the alignment of the label within its allocation.
    /// See [`xalign`][struct@crate::Label#xalign] for that.
    ///
    /// Readable | Writable
    ///
    ///
    /// #### `label`
    ///  The contents of the label.
    ///
    /// If the string contains Pango markup (see `parse_markup()`),
    /// you will have to set the [`use-markup`][struct@crate::Label#use-markup] property to
    /// true in order for the label to display the markup attributes. See also
    /// [`Label::set_markup()`][crate::Label::set_markup()] for a convenience function that sets both
    /// this property and the [`use-markup`][struct@crate::Label#use-markup] property at the
    /// same time.
    ///
    /// If the string contains underlines acting as mnemonics, you will have to
    /// set the [`use-underline`][struct@crate::Label#use-underline] property to true in order
    /// for the label to display them.
    ///
    /// Readable | Writable
    ///
    ///
    /// #### `lines`
    ///  The number of lines to which an ellipsized, wrapping label
    /// should display before it gets ellipsized. This both prevents the label
    /// from ellipsizing before this many lines are displayed, and limits the
    /// height request of the label to this many lines.
    ///
    /// ::: warning
    ///     Setting this property has unintuitive and unfortunate consequences
    ///     for the minimum _width_ of the label. Specifically, if the height
    ///     of the label is such that it fits a smaller number of lines than
    ///     the value of this property, the label can not be ellipsized at all,
    ///     which means it must be wide enough to fit all the text fully.
    ///
    /// This property has no effect if the label is not wrapping or ellipsized.
    ///
    /// Set this property to -1 if you don't want to limit the number of lines.
    ///
    /// Readable | Writable
    ///
    ///
    /// #### `max-width-chars`
    ///  The desired maximum width of the label, in characters.
    ///
    /// If this property is set to -1, the width will be calculated automatically.
    ///
    /// See the section on [text layout](class.Label.html#text-layout) for details
    /// of how [`width-chars`][struct@crate::Label#width-chars] and [`max-width-chars`][struct@crate::Label#max-width-chars]

    ///  The mnemonic accelerator key for the label.

    ///
    /// #### `mnemonic-widget`

    /// Readable | Writable
    ///
    ///
    /// #### `natural-wrap-mode`
    ///  Select the line wrapping for the natural size request.
    ///
    /// This only affects the natural size requested. For the actual wrapping
    /// used, see the [`wrap-mode`][struct@crate::Label#wrap-mode] property.
    ///
    /// The default is [enum@Gtk.NaturalWrapMode.inherit], which inherits
    /// the behavior of the [`wrap-mode`][struct@crate::Label#wrap-mode] property.

    /// #### `selectable`
    ///  Whether the label text can be selected with the mouse.

    /// Readable | Writable
    ///
    ///
    /// #### `single-line-mode`
    ///  Whether the label is in single line mode.
    ///
    /// In single line mode, the height of the label does not depend on the
    /// actual text, it is always set to ascent + descent of the font. This
    /// can be an advantage in situations where resizing the label because
    /// of text changes would be distracting, e.g. in a statusbar.

    ///  Controls how the line wrapping is done.
    ///
    /// This only affects the formatting if line wrapping is on (see the
    /// [`wrap`][struct@crate::Label#wrap] property). The default is [enum@Pango.WrapMode.word],
