Tim Janik 698c89e5c4 GTK_MENU_DIR_CHILD: check for the existance of 
Thu Sep  3 04:22:20 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkmenushell.c (gtk_real_menu_shell_move_current):
        GTK_MENU_DIR_CHILD: check for the existance of
        menu_shell->active_menu_item before accessing its child.
        GTK_MENU_DIR_PREV:
        GTK_MENU_DIR_NEXT: if we haven't had an active item and still
        don't, make a default selection.

Wed Sep  2 00:28:58 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkwidget.c (gtk_widget_propagate_state): iterate
        the children with _forall for sensitivity changes and with
        _foreach on pure state changes. this fixes a lot of the
        old inclusions of internal widgets into _foreach calls.

        * gtk/gtktree.c: removed gtk_tree_foreach, let gtk_tree_forall
        do the work. don't walk the subtrees of first level children.

        * gtk/gtktreeitem.c: provide a _forall implementation,
        which walks the subtrees as well for include_internals.

        * gtk/gtkmenuitem.c: provide a _forall implementation, which walks
        the submenus as well for include_internals.

        * gtk/gtkscrolledwindow.c: removed gtk_scrolled_window_foreach and
        implemented gtk_scrolled_window_forall, which will iterate over
        the viewport and the scrollbars for gtk_container_forall or
        iterate over the viewports children for gtk_container_foreach.

        * gtk/gtktoolbar.c:
        * gtk/gtktable.c:
        * gtk/gtkpaned.c:
        * gtk/gtkpacker.c:
        * gtk/gtkmenushell.c:
        * gtk/gtklist.c:
        * gtk/gtkfixed.c:
        * gtk/gtkclist.c:
        * gtk/gtkbox.c:
        * gtk/gtkbin.c:
        * gtk/gtknotebook.c:
        removed the old gtk_*_foreach functions and provided gtk_*_forall.

        * gtk/gtknotebook.c:
        (gtk_notebook_real_switch_page): expose tabs.
        (gtk_notebook_page_num): new function to return the page number
        of a distinct child.
        (gtk_notebook_focus): minor fixups. foxus handling is still screwed
        under some circumstances.

        * gtk/gtktreeitem.c:
        (gtk_real_tree_item_select):
        (gtk_real_tree_item_deselect): major fixes.
        some general fixups wrt queue_redraw, and tree items not being
        NO_WINDOW widgets.

        * gtk/gtklistitem.c:
        (gtk_real_list_item_select):
        (gtk_real_list_item_deselect):
        (gtk_real_list_item_toggle):
        removed unneccessary queue_redraw calls.

Wed Aug 30 09:42:07 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkoptionmenu.c: allow optionmenus to have the focus and
        automatically popup the menu on space bar.

Wed Aug 26 06:40:34 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkcontainer.h:
        * gtk/gtkcontainer.c: implemented gtk_container_forall() (as a class
        method), which acts similar to gtk_container_foreach(), but iterates
        over internal children. the GtkContainer::foreach signal vanished in
        favour of a new class method ->forall() that optionally includes
        internal widgets.

        * gtk/gtkclist.c (gtk_clist_init): provide no _foreach implementation
        but a _forall implementation, since all child widgets we have are
        internal ones.
        (column_button_create): set the parent window prior
        to gtk_widget_set_parent().

        * gtk/gtkwidget.c:
        exchanged all calls to gtk_container_foreach() with
        gtk_container_forall().

        * gtk/gtkwidget.h:
        * gtk/gtkwidget.c: added the GTK_COMPOSITE_CHILD, exported through
        the GtkWidget::composite_child argument. to have a widget created
        with the flag initially, two new functions got added to wrap a widgets
        creation:
        gtk_widget_push_composite_flag() and gtk_widget_pop_composite_flag().

Wed Aug 25 23:37:39 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtktooltips.h:
        * gtk/gtktooltips.c: exported gtk_tooltips_create_window() as
        gtk_tooltips_force_window(), so tooltips->tip_window can be accessed
        prior to the first tip being set.
        don't put an extra reference on the window, since it is a toplevel,
        it wont get destroyed from anywhere else.

        * overall macro and GtkType fixups.
