Thu Jul 16 18:24:41 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtknotebook.h:
        * gtk/gtknotebook.c: signdness corrections all ove the place.
        implementation of object arguments: GtkNotebook::enable_popup,
        GtkNotebook::tab_pos, GtkNotebook::tab_border, GtkNotebook::show_tabs,
        GtkNotebook::show_border, GtkNotebook::scrollable and GtkNotebook::page.
        begun implementation of child args, we have GtkNotebook::tab_label, but
        GtkNotebook::menu_label and GtkNotebook::position still lack the
        implementation.
        (gtk_notebook_remove_page):
        (gtk_notebook_current_page): allow negative indices (-1) as alias for
        the last page.

        * gtk/gtkentry.h:
        * gtk/gtkentry.c: GtkType and macro fixups. implementation of object
        arguments GtkEntry::max_length and GtkEntry::visibility.
        (gtk_entry_adjust_scroll): queue a redraw.

        * gtk/gtkeditable.h:
        * gtk/gtkeditable.c: GtkType und macro fixups. implementation of
        object arguments GtkEditable::text_position and GtkEditable::editable.
        new (action) signal GtkEditable::set_editable.
        provide a default handler for GtkEditable::changed that queues a redraw.

        * gtk/gtktext.h:
        * gtk/gtktext.c: GtkType und macro fixups. override GtkEditable::
        set_editable.
