    /// GtkLevelBar has a main CSS node with name levelbar and one of the style

    /// ## Properties
    ///
    ///

    /// #### `mode`
    ///  The [`mode`][struct@crate::LevelBar#mode] property determines the way [`LevelBar`][crate::LevelBar]

    /// Specifically, when the value is [`LevelBarMode::Continuous`][crate::LevelBarMode::Continuous],
    /// [`LevelBar`][crate::LevelBar] will draw a single block representing the current value in
    /// that area; when the value is [`LevelBarMode::Discrete`][crate::LevelBarMode::Discrete],
    /// the widget will draw a succession of separate blocks filling the
    /// draw area, with the number of blocks being equal to the units separating
