-- This widget is an abstract widget designed to support the common
-- functionalities of all widgets for editing text. It provides general
-- services to manipulate an editable widget, a large number of action
-- signals used for key bindings, and several signals that an
-- application can connect to to modify the behavior of a widget.

---------------
-- Signals --
---------------
-- <signals>
-- The following new signals are defined for this widget:
--
-- - "changed"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class);
--
-- emitted when the user has changed the text of the widget.
--
-- - "insert_text"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Text : in UTF8_String;
-- Length : in Gint;
-- Position : in Gint_Access);
--
-- Emitted when some text is inserted inside the widget by the
-- user. The default handler inserts the text into the widget.
-- By connecting a handler to this signal, and then by stopping
-- the signal with Gtk.Handlers.Emit_Stop_By_Name, it is possible
-- to modify the inserted text, or even prevent it from being
-- inserted.
-- Position.all should be modified by the callback, and indicates
-- the new position of the cursor after the text has been inserted.
--
-- - "delete_text"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Start_Pos : in Gint;
-- End_Pos : in Gint);
--
-- Emitted when some text is deleted by the user. As for the
-- "insert-text" handler, it is possible to override the default
-- behavior by connecting a handler to this signal, and then
-- stopping the signal.
--
-- - "activate"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class);
--
-- Emitted when the user has activated the widget in some fashion.
--
-- - "set-editable"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Is_Editable: in Boolean);
--
-- Emitting this signal is equivalent to calling Set_Old_Editable.
--
-- - "move_cursor"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- X, Y : in Gint);
--
-- Emitting this signal will move the cursor position for X
-- characters horizontally, and Y characters vertically.
--
-- - "move_word"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- N : in Gint);
--
-- Emitting this signal will move the cursor by N words (N can be
-- negative).
--
-- - "move_page"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- X, Y : in Gint);
--
-- Emitting this signal will move the cursor for X pages
-- horizontally, and Y pages vertically.
--
-- - "move_to_row"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Row : in Gint);
--
-- Emitting this signal will move the cursor to the given row.
--
-- - "move_to_column"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Column : in Gint);
--
-- Emitting this signal will move the cursor to the given column.
--
-- - "kill_char"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Direction : in Gint);
--
-- Emitting this signal deletes a single character. If Direction
-- is positive, delete forward, else delete backward.
--
-- - "kill_word"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Direction : in Gint);
--
-- Emitting this signal deletes a single word. If Direction is
-- positive, delete forward, otherwise delete backward.
--
-- - "kill_line"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class;
-- Direction : in Gint);
--
-- Emitting this signal deletes a single line. If Direction is
-- positive, delete forward, otherwise delete backward.
--
-- - "cut_clipboard"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class);
--
-- Emitting this signal will cut the current selection to the
-- clipboard.
--
-- - "copy_clipboard"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class);
--
-- Emitting this signal will copy the current selection to the
-- clipboard.
--
-- - "paste_clipboard"
-- procedure Handler (Widget : access Gtk_Old_Editable_Record'Class);
--
-- Emitting this signal will paste the clipboard into the text
-- of the widget at the current cursor position.
