From f23e9496f303995557b744c03178f5dbd9b35016 Mon Sep 17 00:00:00 2001 From: Peter Penz Date: Sat, 30 Jul 2011 20:13:09 +0200 Subject: Merged very early alpha-version of Dolphin 2.0 Dolphin 2.0 will get a new view-engine with the following improvements: - Better performance - Animated transitions - No clipped filenames due to dynamic item-sizes - Grouping support for all view-modes - Non-rectangular selection areas - Simplified code for better maintenance More details will be provided in a blog-entry during the next days. Please note that the code is in a very early alpha-stage and although the most tricky parts have been implemented already very basic things like drag and drop or selections have not been pushed yet. Those things are rather trivial to implement but this still will take some time. --- src/tests/kfileitemmodeltest.cpp | 210 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 210 insertions(+) create mode 100644 src/tests/kfileitemmodeltest.cpp (limited to 'src/tests/kfileitemmodeltest.cpp') diff --git a/src/tests/kfileitemmodeltest.cpp b/src/tests/kfileitemmodeltest.cpp new file mode 100644 index 000000000..82fc3fbc0 --- /dev/null +++ b/src/tests/kfileitemmodeltest.cpp @@ -0,0 +1,210 @@ +/*************************************************************************** + * Copyright (C) 2011 by Peter Penz * + * * + * 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.
