    ///
    ///
    ///
    /// #### `child-notify`
    ///  The ::child-notify signal is emitted for each

    ///
    /// #### `configure-event`
    ///  The ::configure-event signal will be emitted when the size, position or
    /// stacking of the `widget`'s window has changed.
    ///
    /// To receive this signal, the [`gdk::Window`][crate::gdk::Window] associated to the widget needs

    ///

    ///
    /// #### `delete-event`
    ///  The ::delete-event signal is emitted if a user requests that

    ///
    ///
    ///
    /// #### `destroy`
    ///  Signals that all holders of a reference to the widget should release

    /// This signal is not suitable for saving widget state.

    ///
    ///
    ///
    /// #### `destroy-event`
    ///  The ::destroy-event signal is emitted when a [`gdk::Window`][crate::gdk::Window] is destroyed.
    /// You rarely get this signal, because most widgets disconnect themselves
    /// from their window before they destroy it, so no widget owns the
    /// window at destroy time.
    ///
    /// To receive this signal, the [`gdk::Window`][crate::gdk::Window] associated to the widget needs
    /// to enable the [`gdk::EventMask::STRUCTURE_MASK`][crate::gdk::EventMask::STRUCTURE_MASK] mask. GDK will enable this mask
    /// automatically for all new windows.
    ///
    ///
    ///

    ///  The ::direction-changed signal is emitted when the text direction
    /// of a widget changes.

    ///
    ///
    ///
    /// #### `drag-begin`
    ///  The ::drag-begin signal is emitted on the drag source when a drag is
    /// started. A typical reason to connect to this signal is to set up a
    /// custom drag icon with e.g. [`WidgetExt::drag_source_set_icon_pixbuf()`][crate::prelude::WidgetExt::drag_source_set_icon_pixbuf()].
    ///
    /// Note that some widgets set up a drag icon in the default handler of
    /// this signal, so you may have to use `g_signal_connect_after()` to
    /// override what the default handler did.
    ///
    ///
    ///
    ///
    /// #### `drag-data-delete`
    ///  The ::drag-data-delete signal is emitted on the drag source when a drag
    /// with the action [`gdk::DragAction::MOVE`][crate::gdk::DragAction::MOVE] is successfully completed. The signal
    /// handler is responsible for deleting the data that has been dropped. What
    /// "delete" means depends on the context of the drag operation.
    ///
    ///
    ///
    ///
    /// #### `drag-data-get`
    ///  The ::drag-data-get signal is emitted on the drag source when the drop
    /// site requests the data which is dragged. It is the responsibility of
    /// the signal handler to fill `data` with the data in the format which

    ///
    ///

    ///  The ::drag-data-received signal is emitted on the drop site when the
    /// dragged data has been received. If the data was received in order to
    /// determine whether the drop will be accepted, the handler is expected
    /// to call `gdk_drag_status()` and not finish the drag.
    /// If the data was received in response to a [`drag-drop`][struct@crate::Widget#drag-drop] signal
    /// (and this is the last target to be received), the handler for this
    /// signal is expected to process the received data and then call
    /// `gtk_drag_finish()`, setting the `success` parameter depending on

    ///
    /// Applications must create some means to determine why the signal was emitted
    /// and therefore whether to call `gdk_drag_status()` or `gtk_drag_finish()`.
    ///
    /// The handler may inspect the selected action with
    /// [`DragContext::selected_action()`][crate::gdk::DragContext::selected_action()] before calling
    /// `gtk_drag_finish()`, e.g. to implement [`gdk::DragAction::ASK`][crate::gdk::DragAction::ASK] as

    ///
    ///
    ///
    /// #### `drag-drop`
    ///  The ::drag-drop signal is emitted on the drop site when the user drops
    /// the data onto the widget. The signal handler must determine whether
    /// the cursor position is in a drop zone or not. If it is not in a drop

    ///
    ///
    ///
    /// #### `drag-end`
    ///  The ::drag-end signal is emitted on the drag source when a drag is

    ///
    ///
    ///
    /// #### `drag-leave`
    ///  The ::drag-leave signal is emitted on the drop site when the cursor

    ///
    /// #### `drag-motion`
    ///  The ::drag-motion signal is emitted on the drop site when the user
