Mon Mar  9 15:48:10 1998  Tim Janik  <timj@gimp.org>

        * Signal signedness and naming corrections, plus GtkType fixes:

        * gtk/gtkadjustment.c:
        * gtk/gtkbutton.c:
        * gtk/gtkcheckmenuitem.c:
        * gtk/gtkclist.c:
        * gtk/gtkcolorsel.c:
        * gtk/gtkcontainer.c:
        * gtk/gtkcurve.c:
        * gtk/gtkdata.c:
        * gtk/gtkeditable.c:
        * gtk/gtkentry.c:
        * gtk/gtkhandlebox.c:
        * gtk/gtkinputdialog.c:
        * gtk/gtkitem.c:
        * gtk/gtklist.c:
        * gtk/gtkmenuitem.c:
        * gtk/gtkmenushell.c:
        * gtk/gtknotebook.c:
        * gtk/gtkstatusbar.c:
        * gtk/gtktoolbar.c:
        * gtk/gtktree.c:
        * gtk/gtktreeitem.c:
        * gtk/gtkwidget.c:
        * gtk/gtktogglebutton.c:
        * gtk/gtkwindow.c:
        made the <widget>_signals[] arrays of type guint rather than gint.
        * gtk/gtkwidget.c (gtk_widget_get_ancestor): made widget_type a GtkType.

        * gtk/gtkcombo.h:
        handler ids need to be of type guint (entry_change_id, list_change_id).

        * gtk/gtkaccelerator.c:
        changed signal_num to signal_id and typed it guint.

        * gtk/gtkmain.c: made gtk_ndebug_keys a guint.

        * gtk/gtkmenu.h:
        * gtk/gtkmenu.c:
        (gtk_menu_popup): made button a guint.
        (gtk_menu_set_active): made index a guint.

        * gtk/gtkmenuitem.h:
        * gtk/gtkmenuitem.c:
        made accelerator_signal a guint.

        * gtk/gtkoptionmenu.h:
        * gtk/gtkoptionmenu.c:
        (gtk_option_menu_set_history): made index a guint.

        * gtk/gtksignal.h:
        * gtk/gtksignal.c:
        * gtk/gtkobject.h:
        * gtk/gtkobject.c: changed a bunch of prototypes to take guints rather
        than gints. also made some conversions from guint to GtkType, left over
        from when the fundamental-types system was introduced.

        * gtk/gtkobject.h:
        * gtk/gtkobject.c: made object_data_id_index and obj_count guints.
        made *signals and nsignals guints in GtkObjectClass.
