made the <widget>_signals[] arrays of type guint rather than gint. made 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.

doh, this was broken beyond believe. Tue Dec 12 23:46:44 2000 Tim Janik <timj@gtk.org> * gtk/stock-icons/Makefile.am: doh, this was broken beyond believe. * gtk/gtkbox.c: change property types from (u)long to (u)int for ::position and ::padding. * gtk/gtkcontainer.c: make ::border_width an INT property. * gtk/gtkpacker.c: make ::position an INT property. * gtk/gtkscrolledwindow.c (gtk_scrolled_window_adjustment_changed): guard against NULL h/v scrollbars, since this is used at construction time. * gtk/gtkclist.[hc]: nuked gtk_clist_construct(), implemented internal gtk_clist_constructor(). * gtk/gtkctree.[hc]: nuked gtk_ctree_construct(), implemented gtk_ctree_constructor(). * gtk/gtkprogressbar.c (gtk_progress_bar_class_init): property ::pulse_step should use ARG_PULSE_STEP, not ARG_FRACTION. * docs/reference/Makefile.am: fun stuff, disabled docs generation again, gtk-scan.c needs to introspec paramspecs, not GtkAgs. * gtk/gtkwidget.[hc]: removed gtk_widget_setv(), gtk_widget_getv(), gtk_widget_newv() and gtk_widget_get(). (gtk_widget_new): use g_object_new_valist(). (gtk_widget_set): use g_object_set_valist(). * gtk/gtkobject.[hc]: removed gtk_object_arg_get_info(), gtk_object_getv(), gtk_object_query_args(), gtk_object_newv(), gtk_object_class_add_signals(), gtk_object_class_user_signal_new(), gtk_object_class_user_signal_newv(), gtk_object_arg_set(), gtk_object_arg_get(), gtk_object_args_collect(), gtk_object_default_construct(), gtk_object_constructed(), GTK_CONSTRUCTED and GTK_OBJECT_CONSTRUCTED(). removed nsignals, signals and n_args members from GtkObjectClass. (gtk_object_new): use g_object_new_valist(). (gtk_object_set): use g_object_set_valist(). (gtk_object_get): use g_object_get_valist(). * gtk/gtkcompat.h: define gtk_object_default_construct(). * gtk/gtktypeutils.c (gtk_type_new): create constructed objects via g_object_new(). * gtk/*.c: removed gtk_object_class_add_signals() from class_init() fucntions, cleaned up method assignments (make sure your structures are setup properly before calling out). removed all GTK_CONSTRUCTED hacks ;)

Added gdk_text/string_extents() - too calculate all the metrics at once of Tue Jul 21 12:42:01 1998 Owen Taylor <otaylor@redhat.com> * gdk/gdk.h gdk/gdkfont.c: Added gdk_text/string_extents() - too calculate all the metrics at once of a string, including things which weren't calculated before. * gtk/Makefile.am gtk/gtk.h gtk/gtktearoffmenu.[ch]: New MenuItem type, that when put as the first thing in a menu, makes the menu tearoff. Currently drawn as a dashed line. * gtk/gtkmenuitem.h gtk/gtkcheckmenuitem.c: Added a flag "hide_on_activate" to the MenuItem class structure to allow check and radio buttons to be changed with <Space> without hiding the menu. * gtk/gtkaccellabel.[ch]: Added new capabilities to set a underline_group and underline_mods for the label - accelerators added in the underline group matching underline_mods will be displayed as an underline character. This doesn't work - Save As needs to be underlined as Save _As. * gtk/gtkitemfactory.c: - Create a AccelGroup for each MenuShell we create. - If an '&' appears before a character 'c' in the path, then make 'c' an accelerator in the menu's accel group, and if the menuitem is menubar <alt>C an accelerator in the itemfactory's accel group. * gtk/gtklabel.[ch]: Add support for a pattern arg - which is a string. If an '_' appears in this string, the corresponding position in the label is underlined. Add gtk_label_parse_uline() convenience function which takes a string with embedded underlines, sets the pattern and label, and returns the accelerator keyval. * gtk/gtkmenu.[ch]: Make menus no longer a toplevel widget. Instead, they create a GtkWindow and add themselves to that. (When torn off, another new feature, they create another GtkWindow to hold the torn off menu) New function gtk_menu_set_tearoff_state() * gtk/gtkenums.h gtk/gtkmenushell.[ch] gtk/gtkenums.h: Added action signals for keyboard navigation of menus. * gtk/gtkmenushell.c: Key press handler which activates bindings for navigation, and accelerators, for handling underline accelerators. Exported functions to select and activate menu items in a menushell. * gtk/testgtk.c: Added a new "Item Factory" test which tests GtkItemFactory and the new keyboard navigation of menus.
