    /// Set whether the event box uses a visible or invisible child
    /// window. The default is to use visible windows.
    ///
    /// In an invisible window event box, the window that the
    /// event box creates is a `GDK_INPUT_ONLY` window, which
    /// means that it is invisible and only serves to receive
    /// events.
    ///
    /// A visible window event box creates a visible (`GDK_INPUT_OUTPUT`)
    /// window that acts as the parent window for all the widgets
    /// contained in the event box.
    ///
    /// You should generally make your event box invisible if
    /// you just want to trap events. Creating a visible window
    /// may cause artifacts that are visible to the user, especially
    /// if the user is using a theme with gradients or pixmaps.
    ///
    /// The main reason to create a non input-only event box is if
    /// you want to set the background to a different color or
    /// draw on it.
    ///
    /// There is one unexpected issue for an invisible event box that has its
    /// window below the child. (See [`set_above_child()`][Self::set_above_child()].)
    /// Since the input-only window is not an ancestor window of any windows
    /// that descendent widgets of the event box create, events on these
    /// windows aren’t propagated up by the windowing system, but only by GTK+.
    /// The practical effect of this is if an event isn’t in the event
    /// mask for the descendant window (see [`WidgetExtManual::add_events()`][crate::prelude::WidgetExtManual::add_events()]),
    /// it won’t be received by the event box.
    ///
    /// This problem doesn’t occur for visible event boxes, because in
    /// that case, the event box window is actually the ancestor of the
    /// descendant windows, not just at the same place on the screen.
