        * merges from gtk-1-2:

Tue Mar 16 17:43:33 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtkitemfactory.c (gtk_item_factory_parse_rc_string): ensure the
        item factory class has been created.
        (gtk_item_factory_parse_rc): likewise.

        * gtk/gtkmenu.c:
        keep proper references for old_active_menu_item.
        (gtk_menu_reparent): unset the usize of the new parent,
        so the menu can sanely be size requested and we don't get nasty screen
        artefacts upon next reparentation.
        (gtk_menu_motion_notify): set send_event to TRUE if we synthesize an
        enter notify. only synthesize enter notifies if the pointer really is
        inside the event window.
        (gtk_menu_popdown): use gtk_menu_shell_deselect().
        (gtk_menu_popup): move the background setting stuff into
        gtk_menu_tearoff_bg_copy() so it can be called from other places as well.

        * gtk/gtkmenushell.c (gtk_menu_shell_button_press): use
        gtk_menu_shell_select_item() to select the new item.
        (gtk_menu_shell_deselect): export this function, so gtkmenu.c can
        do the right thing for deselection as well.

Sat Mar 15 20:10:33 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtkwidget.[hc]:
        (gtk_widget_accelerators_locked): return whether a widget's accelerators
        are locked.

        * gtk/gtkmenu.c (gtk_menu_key_press): don't remove or install new or
        existing accelerators if the widget's accelerators are locked.

Sat Mar 14 19:44:05 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtkitemfactory.[hc]: allow managing of foreign menu items.

        * gtk/gtkmenu.c: truely forward key press and key release events to
        the menu widget from the toplevel or tearoff window. we can't simply
        connect to that, we need to stop further processing of the events as
        well.

Sat Mar 13 13:14:17 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtkmenu.c:
        (gtk_menu_key_press): pass event->keyval, event->state to
        gtk_accelerator_valid, instead of event->keyval twice.
        refuse to install single letter accelerators for menus that use
        single letter shortcuts.

        * gtk/gtkitemfactory.c (gtk_item_factory_create_item): use
        gtk_menu_ensure_uline_accel_group().

        * gtk/gtkmenu.[hc]: added gtk_menu_ensure_uline_accel_group()
        which will always return an uline accel group, made
        gtk_menu_get_uline_accel_group() return NULL if the group isn't
        yet created.

Mon Mar 15 01:03:27 1999  Lars Hamann  <lars@gtk.org>

        * gtk/gtkclist.h (struct _GtkCListColumn): added button_passive flag.

        * gtk/gtkclist.c (gtk_clist_column_title_passive):
        Leave button sensitive, trap  button_press, button_release,
        motion_notify, enter_notify and leave_notify events instead.
        (gtk_clist_column_title_active): disconnect event handler.
        (gtk_clist_drag_data_get): fixed memory leak. Reported by
        Guillaume Laurent <glaurent@worldnet.fr>

Wed Mar 10 23:49:55 1999  Lars Hamann  <lars@gtk.org>

        * gtk/gtklayout.c (gtk_layout_adjustment_changed): fixed a few
        width/height mixups.

        * gtk/gtkctree.c (tree_delete): emit an tree_unselect_row signal
        if needed.

Wed Mar 10 00:11:32 1999  Tim Janik  <timj@gtk.org>

        * gtk/testgtk.c (create_item_factory): unref the item factory after
        window's destruction.

        * gtk/gtkmenushell.c (gtk_menu_shell_activate_item): keep a reference
        count on the menu shell around the menu item's activation, since the
        signal emission may cause menu shell destruction.

        * gtk/gtkitemfactory.c:
        the previous code leaked one accel group per menu. we use
        gtk_menu_get_uline_accel_group() now to fix that, and with that
        also create the underline accelerator group of the menus only if
        required (i.e. an underline accelerator has been specified).
        (gtk_item_factory_construct):
        (gtk_item_factory_create_item): removed code that would create an
        extra accel group for the menu (and leak references).
        (gtk_item_factory_create_item): adapted the underline accelerator
        installation code to properly feature gtk_menu_get_uline_accel_group().

        * gtk/gtkmenu.[hc]: added gtk_menu_get_accel_group() to retrive
        menu->accel_group, this may return NULL if the accelerator group
        hasn't been set yet.
        added gtk_menu_get_uline_accel_group() to retrive the underline
        accelerator group of the menu, this will be created on demand
        and proper care is taken about its reference count.

        * gtk/gtkitemfactory.h:
        * gtk/gtkitemfactory.c:
        dumped the approach of keeping a widgets by action list on the
        factory since the factory<->widget destroy negotiation didn't work
        and would be hard to get going at all. instead we keep a list of
        GtkItemFactoryItem items on the factory (GtkItemFactoryItems are
        persistant throughout a program's life time).
        also, i removed the static const gchar *key_* variables, and made
        them inline strings (they weren't actually used anyways).
        (gtk_item_factory_add_item): update ifactory->items.
        (gtk_item_factory_destroy): destroy ifactory->items (and remove
        the item factory pointer from the remaining ifactory widgets).
        (gtk_item_factory_get_widget_by_action): walk the GtkItemFactoryItem
        list to find the widget.
        (gtk_item_factory_get_item): new function that works around
        gtk_item_factory_get_widget() limitations, this function will only
        return menu items, even for <Branch> entries.

Tue Mar  9 01:01:28 1999  Tim Janik  <timj@gtk.org>

        * gdk/gdkfont.c (gdk_font_load): first lookup the xfont ID in our
        font hash table, if we have a GdkFontPrivate entry for this font
        already, simply increment its reference count, provided by Olaf Dietsche
        <olaf.dietsche+list.gtk@netcologne.de>.

        * gtk/gtkstyle.c (gtk_style_copy): plug a GdkFont reference leak, fix
        provided by Olaf Dietsche <olaf.dietsche+list.gtk@netcologne.de>.

Sun Mar  7 06:13:29 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtkcontainer.c:
        (gtk_container_add_with_args):
        (gtk_container_addv):
        (gtk_container_add): before adding a child to a conatiner, make sure
        it is (default) constructed, this is neccessary because under certain
        circumstances the child will get relized and mapped immediatedly, in
        which case it has to be constructed already.

Mon Mar  1 17:58:21 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtksignal.c (gtk_signal_connect_by_type): count object_signal
        values > 1 as TRUE also.
