new signal GtkCList::resize_column. don't draw invisible columns

Wed Oct  7 00:59:46 1998  Lars Hamann  <lars@gtk.org>

        * gtk/gtkclist.h: new signal GtkCList::resize_column.
        * gtk/gtkclist.c (draw_row): don't draw invisible columns
        (size_allocate_title_buttons) (size_allocate_columns):
        skip invisible columns
        (new_column_width): take min/max_width into account
        (gtk_clist_button_release) (gtk_clist_motion):
        changes due to changed new_column_width function
        (LIST_WIDTH): changed define to inline function.
        (real_resize_column): class function for resize_column signal
        (gtk_clist_motion): fixed autoscrolling for column resizes
        (gtk_clist_set_column_visibility): don't hide last visible column,
        changed visible arg to gboolean
        (gtk_clist_set_column_min_width)(gtk_clist_set_column_max_width):
        new functions : set min/max width of a column
        (gtk_clist_set_column_resizeable): new function : enable/disable
        column resize operations by mouse

        * gtk/gtkctree.c (draw_row): don't draw invisible columns
        (ctree_is_hot_spot): return FALSE if tree_column is invisible
        (draw_xor_line)  (draw_xor_rect): draw full rectangle/line if
        tree_column is invisible
        (gtk_ctree_find_all_by_row_data)
        (gtk_ctree_find_all_by_row_data_custom):  new function from
        Ronan Bourlier <ronan@radioss.com>. Returns a GList of all
        GtkCTreeNodes with row->data == data.
