gtk_editable_set_position ()

void        gtk_editable_set_position       (GtkEditable *editable,
                                             gint position);

   Sets the cursor position.

   editable : a GtkEditable widget.      
   position : the position of the cursor. The cursor is displayed
   before the character with the given (base 0) index in the
   widget. The value must be less than or equal to the number of
   characters in the widget. A value of -1 indicates that the position
   should be set after the last character in the entry.  Note that
   this position is in characters, not in bytes.

gtk_editable_delete_text ()

void        gtk_editable_delete_text        (GtkEditable *editable,
                                             gint start_pos,
                                             gint end_pos);

   Delete a sequence of characters. The characters that are deleted
   are those characters at positions from start_pos up to, but not
   including end_pos. If end_pos is negative, then the the characters
   deleted will be those characters from start_pos to the end of the
   text.

   editable : a GtkEditable widget.
   start_pos : the starting position.
   end_pos : the end position.
