Sun Mar  3 06:39:19 2002  Tim Janik  <timj@gtk.org>

        * gtk/gtkfilesel.c: added compile time switch to put the tree views
        into a hpaned for owen to play with.

        * gtk/gtktreedatalist.c (_gtk_tree_data_list_header_free):
        * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_cell_data_func),
        (gtk_tree_view_column_finalize):
        * gtk/gtktreestore.c (gtk_tree_store_set_default_sort_func),
        (gtk_tree_store_set_sort_func), (gtk_tree_store_finalize):
        * gtk/gtktreeselection.c (gtk_tree_selection_finalize):
        * gtk/gtktreemodelsort.c (gtk_tree_model_sort_reset_default_sort_func),
        (gtk_tree_model_sort_set_default_sort_func),
        (gtk_tree_model_sort_set_sort_func):
        * gtk/gtkliststore.c (gtk_list_store_set_default_sort_func),
        (gtk_list_store_set_default_sort_func),
        (gtk_list_store_set_sort_func), (gtk_list_store_finalize):
        add reentrancy protection around destroy() function invocation.

        * gtk/gtktreeselection.c (gtk_tree_selection_set_select_function): fix
        destroy function invocation (which was missing).
