From dbe2152912cc58f1d2bfba187175ec0e4b3e4761 Mon Sep 17 00:00:00 2001 From: Peter Penz Date: Thu, 18 Aug 2011 23:11:16 +0200 Subject: Provide basic rubberband functionality This is just a rough draft: The rubberband gets visible and an automatic scrolling is done if the autoscroll-margins have been reached. However currently no items get selected yet. Currently the autoscrolling has a severe bug if the scrollbars are manually changed before or after a rubberband selection. --- src/kitemviews/kitemlistrubberband_p.h | 60 ++++++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 src/kitemviews/kitemlistrubberband_p.h (limited to 'src/kitemviews/kitemlistrubberband_p.h') diff --git a/src/kitemviews/kitemlistrubberband_p.h b/src/kitemviews/kitemlistrubberband_p.h new file mode 100644 index 000000000..aea58af46 --- /dev/null +++ b/src/kitemviews/kitemlistrubberband_p.h @@ -0,0 +1,60 @@ +/*************************************************************************** + * 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.
