    ///
    ///
    /// #### `changed`
    ///  The ::changed signal is emitted at the end of a single
    /// user-visible operation on the contents of the [`Editable`][crate::Editable].
    ///
    /// E.g., a paste operation that replaces the contents of the
    /// selection will cause only one signal emission (even though it
    /// is implemented by first deleting the selection, then inserting
    /// the new content, and may cause multiple ::notify::text signals
    /// to be emitted).
    ///
    ///
    ///
    ///
    /// #### `delete-text`
    ///  This signal is emitted when text is deleted from
    /// the widget by the user. The default handler for
    /// this signal will normally be responsible for deleting
    /// the text, so by connecting to this signal and then
    /// stopping the signal with `g_signal_stop_emission()`, it
    /// is possible to modify the range of deleted text, or
    /// prevent it from being deleted entirely. The `start_pos`
    /// and `end_pos` parameters are interpreted as for
    /// [`EditableExt::delete_text()`][crate::prelude::EditableExt::delete_text()].
    ///
    ///
    ///
    ///
    /// #### `insert-text`
    ///  This signal is emitted when text is inserted into
    /// the widget by the user. The default handler for
    /// this signal will normally be responsible for inserting
    /// the text, so by connecting to this signal and then
    /// stopping the signal with `g_signal_stop_emission()`, it
    /// is possible to modify the inserted text, or prevent
    /// it from being inserted entirely.
