    /// `gtk_info_bar_new_with_buttons()`. The sensitivity of action widgets
    /// can be controlled with [`InfoBarExt::set_response_sensitive()`][crate::prelude::InfoBarExt::set_response_sensitive()].
    /// To add widgets to the main content area of a [`InfoBar`][crate::InfoBar], use
    /// [`InfoBarExt::content_area()`][crate::prelude::InfoBarExt::content_area()] and add your widgets to the container.

    /// Similar to [`MessageDialog`][crate::MessageDialog], the contents of a [`InfoBar`][crate::InfoBar] can by
