    /// [`SignalGroup`][crate::SignalGroup] manages to simplify the process of connecting
    /// many signals to a [`glib::Object`][crate::glib::Object] as a group. As such there is no API
    /// to disconnect a signal from the group.
    ///
    /// In particular, this allows you to:
    ///
    ///  - Change the target instance, which automatically causes disconnection
    ///  of the signals from the old instance and connecting to the new instance.
    ///  - Block and unblock signals as a group
    ///  - Ensuring that blocked state transfers across target instances.
    ///
    /// One place you might want to use such a structure is with `GtkTextView` and
    /// `GtkTextBuffer`. Often times, you'll need to connect to many signals on
    /// `GtkTextBuffer` from a `GtkTextView` subclass. This allows you to create a
    /// signal group during instance construction, simply bind the
    /// `GtkTextView:buffer` property to [`target`][struct@crate::SignalGroup#target] and connect
    /// all the signals you need. When the `GtkTextView:buffer` property changes
    /// all of the signals will be transitioned correctly.
