From 7f36752a67c274640378ec096f37e690fd5ca8ed Mon Sep 17 00:00:00 2001 From: Ettore Perazzoli Date: Fri, 9 Jun 2000 19:19:36 +0000 Subject: Initial support for creating/removing folders. This implies some new IDL methods and new functions to implement on the component side. I have also added a simple folder creation dialog in the shell. It's quite unfinished and untested. svn path=/trunk/; revision=3491 --- shell/evolution-shell-component-client.c | 507 +++++++++++++++++++++++++++++++ 1 file changed, 507 insertions(+) create mode 100644 shell/evolution-shell-component-client.c (limited to 'shell/evolution-shell-component-client.c') diff --git a/shell/evolution-shell-component-client.c b/shell/evolution-shell-component-client.c new file mode 100644 index 0000000000..53a4933142 --- /dev/null +++ b/shell/evolution-shell-component-client.c @@ -0,0 +1,507 @@ +/* -*- Mode: C; indent-tabs-mode: t; c-basic-offset: 8; tab-width: 8 -*- */ +/* evolution-shell-component-client.c + * + * Copyright (C) 2000 Helix Code, Inc. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of the + * License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
