Gtk.Label.prototype.set_line_wrap_mode

function set_line_wrap_mode(wrap_mode:Pango.WrapMode):void {
    // Gjs wrapper for gtk_label_set_line_wrap_mode()
}

If line wrapping is on (see Gtk.Label.prototype.set_line_wrap) this controls how the line wrapping is done. The default is Pango.WrapMode.word which means wrap on word boundaries.
