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.
