From a96166710faf2447ed10194d1829db5564b0dff9 Mon Sep 17 00:00:00 2001 From: David Robillard Date: Fri, 4 May 2007 03:59:38 +0000 Subject: Made engine, serialisation, client library, and GUI all dynamically loaded modules. Combined all executables into a single "ingen" program which can do everything. git-svn-id: http://svn.drobilla.net/lad/ingen@493 a436a847-0d15-0410-975c-d299462d15a1 --- src/libs/gui/DSSIController.cpp | 279 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 279 insertions(+) create mode 100644 src/libs/gui/DSSIController.cpp (limited to 'src/libs/gui/DSSIController.cpp') diff --git a/src/libs/gui/DSSIController.cpp b/src/libs/gui/DSSIController.cpp new file mode 100644 index 00000000..f245d61f --- /dev/null +++ b/src/libs/gui/DSSIController.cpp @@ -0,0 +1,279 @@ +/* This file is part of Ingen. + * Copyright (C) 2007 Dave Robillard + * + * Ingen 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. + * + * Ingen 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.
