Lars Hamann 8ad52d1024 Few fixes for column resize. Store resize column in clist->drag_pos. 
Fri Jul 31 20:45:07 1998  Lars Hamann  <lars@gtk.org>

        * gtk/gtkclist.c (gtk_clist_button_press) (gtk_clist_motion)
        (gtk_clist_button_release) (new_column_width): Few fixes for
        column resize. Store resize column in clist->drag_pos.

Thu Jul 31 15:18:36 1998  Lars Hamann  <lars@gtk.org>

        * gtk/gtkctree.h
        * gtk/gtkctree.c
        * gtk/testgtk.c : New typedef GtkCTreeNode, changed all GList *node
        to GtkCTreeNode *node.

        * gtk/gtklist.h : added extended selection mode and auto scrolling.
        (struct _GtkList): removed unneeded variables timer, button,
        selection_start_pos, selection_end_pos, scroll_direction, have_grab.
        Added new variables undo_selection, undo_unselection, last_focus_child,
        undo_focus_child, htimer, vtimer, anchor, drag_pos, anchor_state,
        drag_selection, add_mode.

        New functions :
        (gtk_list_extend_selection), (gtk_list_start_selection),
        (gtk_list_end_selection), (gtk_list_select_all),
        (gtk_list_unselect_all), (gtk_list_scroll_horizontal),
        (gtk_list_scroll_vertical), (gtk_list_toggle_add_mode),
        (gtk_list_toggle_focus_row), (gtk_list_toggle_row),
        (gtk_list_undo_selection), (gtk_list_end_drag_selection)

        * gtk/gtklist.c :
        (gtk_list_enter_notify): removed, because auto scrolling now works
        with gtk_list_motion_notify

        New functions, needed for auto scrolling :
        (gtk_list_motion_notify) (gtk_list_move_focus_child)

        New functions for extended selection support :
        (gtk_list_set_anchor), (gtk_list_fake_unselect_all),
        (gtk_list_fake_toggle_row), (gtk_list_update_extended_selection),
        (gtk_list_focus_lost)

        (gtk_list_set_focus_child): modified gtk_container_set_focus_child
        function to support auto scrolling, and avoid out-of-sync errors in
        case auf GTK_SELECTION_BROWSE
        (gtk_list_focus): modified gtk_container_focus function to avoid out
        off sync errors in case auf GTK_SELECTION_EXTENDED

        * gtk/gtklistitem.h
        * gtk/gtklistitem.c :
        New signal functions for key binding support :
        (toggle_focus_row), (select_all), (list_item), (unselect_all)
        (list_item), (undo_selection), (start_selection), (end_selection)
        (extend_selection), (scroll_horizontal), (scroll_vertical),
        (toggle_add_mode)
        (gtk_list_item_realize): added  GDK_KEY_PRESS_MASK |
        GDK_KEY_RELEASE_MASK
        (gtk_list_item_draw_focus): modify gc if parent has add_mode set.

        * gtk/gtkcombo.c :
        (gtk_combo_popup_button_press):  grab pointer for combo->list
        (gtk_combo_button_release): ungrab only if combo->popwin HAS_GRAB
        (gtk_combo_list_key_press): take care of which child HAS_GRAB
        (gtk_comb_init): don't connect combo->button with button_release_event
