From f0d3f3afdfa314e1e8cd7d8da790878008a46aad Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Wed, 24 Jun 2009 12:59:33 -0400 Subject: Radically reorganize source code. - Collect all shell modules into a new top-level 'modules' directory: $(top_srcdir)/modules/addressbook $(top_srcdir)/modules/calendar $(top_srcdir)/modules/mail Nothing is allowed to link to these, not plugins nor other modules. THIS SOLVES BUG #571275 AND OPENS THE DOOR TO PORTING TO MAC OS X. - Mimic the libevolution-mail-shared library from master (except drop the "shared" suffix) and have libevolution-mail-importers and all mail-related plugins link to it. - Discard the a11y subdirectories and have the files live alongside their counterpart widgets. --- calendar/gui/ea-week-view.c | 321 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 321 insertions(+) create mode 100644 calendar/gui/ea-week-view.c (limited to 'calendar/gui/ea-week-view.c') diff --git a/calendar/gui/ea-week-view.c b/calendar/gui/ea-week-view.c new file mode 100644 index 0000000000..97a8dae25d --- /dev/null +++ b/calendar/gui/ea-week-view.c @@ -0,0 +1,321 @@ +/* + * 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.
