    /// applied to the whole text. Note that specifying ranges does not make much

    /// # Mnemonics
    ///
    /// Labels may contain “mnemonics”. Mnemonics are underlined characters in the

    /// **⚠️ The following code is in c ⚠️**

    ///
    /// ```c
    /// GtkWidget *label = gtk_label_new (NULL);
    /// gtk_label_set_markup (GTK_LABEL (label), "<small>Small text</small>");
    /// ```
    ///
    /// (See the Pango manual for complete documentation] of available
    /// tags, `parse_markup()`)
    ///
    /// The markup passed to gtk_label_set_markup() must be valid; for example,
    /// literal <, > and & characters must be escaped as &lt;, &gt;, and &amp;.
    /// If you pass text obtained from the user, file, or a network to
    /// [`set_markup()`][Self::set_markup()], you’ll want to escape it with
    /// g_markup_escape_text() or g_markup_printf_escaped().
    ///
    /// Markup strings are just a convenient way to set the [`pango::AttrList`][crate::pango::AttrList]
    /// on a label; [`set_attributes()`][Self::set_attributes()] may be a simpler way to set
    /// attributes in some cases. Be careful though; [`pango::AttrList`][crate::pango::AttrList] tends
    /// to cause internationalization problems, unless you’re applying attributes
    /// to the entire string (i.e. unless you set the range of each attribute
    /// to [0, `G_MAXINT`)). The reason is that specifying the start_index and
    /// end_index for a `Pango::Attribute` requires knowledge of the exact
    /// string being displayed, so translations will cause problems.
    ///
    /// # Selectable labels
    ///
    /// Labels can be made selectable with [`set_selectable()`][Self::set_selectable()].
    /// Selectable labels allow the user to copy the label contents to
    /// the clipboard. Only labels that contain useful-to-copy information
    /// — such as error messages — should be made selectable.
    ///
    /// # Text layout
    ///
    /// A label can contain any number of paragraphs, but will have
    /// performance problems if it contains more than a small number.
    /// Paragraphs are separated by newlines or other paragraph separators
    /// understood by Pango.
    ///
    /// Labels can automatically wrap text if you call [`set_wrap()`][Self::set_wrap()].
    ///
    /// [`set_justify()`][Self::set_justify()] sets how the lines in a label align
    /// with one another. If you want to set how the label as a whole aligns
    /// in its available space, see the `property::Widget::halign` and
    /// `property::Widget::valign` properties.
    ///
    /// The `property::Label::width-chars` and `property::Label::max-width-chars`
    /// properties can be used to control the size allocation of ellipsized or
    /// wrapped labels. For ellipsizing labels, if either is specified (and less
    /// than the actual text size), it is used as the minimum width, and the actual
    /// text size is used as the natural width of the label. For wrapping labels,
    /// width-chars is used as the minimum width, if specified, and max-width-chars
    /// is used as the natural width. Even if max-width-chars specified, wrapping
    /// labels will be rewrapped to use all of the available width.
    ///
    /// # Links
    ///
    /// GTK supports markup for clickable hyperlinks in addition to regular Pango
    /// markup. The markup for links is borrowed from HTML, using the `<a>` with
    /// “href“, “title“ and “class“ attributes. GTK renders links similar to the
    /// way they appear in web browsers, with colored, underlined text. The “title“
    /// attribute is displayed as a tooltip on the link. The “class“ attribute is
    /// used as style class on the CSS node for the link.
    ///
    /// An example looks like this:
    ///
    /// **⚠️ The following code is in c ⚠️**
    ///
    /// ```c
    /// const char *text =
    /// "Go to the"
    /// "<a href=\"http://www.gtk.org title=\"&lt;i&gt;Our&lt;/i&gt; website\">"
    /// "GTK website</a> for more...";
    /// GtkWidget *label = gtk_label_new (NULL);
