From b106b13525048195d99bcbde31e0e535972cbab4 Mon Sep 17 00:00:00 2001 From: Ettore Perazzoli Date: Sat, 23 Jun 2001 06:46:13 +0000 Subject: Implemented an Evolution::Activity interface for keeping track of background tasks. The Activity interface is added to the shell, and the status of the various tasks is now displayed in a task bar widget at the bottom of the EShellView. I also implemented a simple test component to test all this stuff. svn path=/trunk/; revision=10434 --- shell/e-task-bar.c | 154 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 154 insertions(+) create mode 100644 shell/e-task-bar.c (limited to 'shell/e-task-bar.c') diff --git a/shell/e-task-bar.c b/shell/e-task-bar.c new file mode 100644 index 0000000000..efc552f661 --- /dev/null +++ b/shell/e-task-bar.c @@ -0,0 +1,154 @@ +/* -*- Mode: C; indent-tabs-mode: t; c-basic-offset: 8; tab-width: 8 -*- */ +/* e-task-bar.c + * + * Copyright (C) 2001 Ximian, 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.
