   -- Signals --
   -------------
   --  The following new signals are defined for this widget:
   --
   --  "editing-done"
   --     procedure Handler (Self : access Gtk_Cell_Editable);
   --  This signal is a sign for the cell renderer to update its value from
   --  the Cell_Editable. Implementations of
   --  Gtk.Cell_Editable.Gtk_Cell_Editable are responsible for emitting this
   --  signal when they are done editing, e.g. Gtk.GEntry.Gtk_Entry is emitting
   --  it when the user presses Enter. Gtk.Cell_Editable.Editing_Done is a
   --  convenience method for emitting GtkCellEditable::editing-done.
   --
   --  "remove-widget"
   --     procedure Handler (Self : access Gtk_Cell_Editable);
   --  This signal is meant to indicate that the cell is finished editing, and
   --  the widget may now be destroyed. Implementations of
   --  Gtk.Cell_Editable.Gtk_Cell_Editable are responsible for emitting this
   --  signal when they are done editing. It must be emitted after the
   --  Gtk.Cell_Editable.Gtk_Cell_Editable::editing-done signal, to give the
   --  cell renderer a chance to update the cell's value before the widget is
   --  removed. Gtk.Cell_Editable.Remove_Widget is a convenience method for
   --  emitting GtkCellEditable::remove-widget.
