From 5eb12906c4242a576ad6fac4d229f096d3aab17a Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Sun, 10 May 2009 13:18:28 -0400 Subject: Use the proper idiom for loading types in a GTypeModule. Also, combine calendar, memo, and task backends into a single module, similar to how it worked under Bonobo. --- calendar/module/e-task-shell-content.c | 700 +++++++++++++++++++++++++++++++++ 1 file changed, 700 insertions(+) create mode 100644 calendar/module/e-task-shell-content.c (limited to 'calendar/module/e-task-shell-content.c') diff --git a/calendar/module/e-task-shell-content.c b/calendar/module/e-task-shell-content.c new file mode 100644 index 0000000000..280bc7cf18 --- /dev/null +++ b/calendar/module/e-task-shell-content.c @@ -0,0 +1,700 @@ +/* + * e-task-shell-content.c + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) version 3. + * + * 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.
