From 0131a3873e0cb05bd357326b441f2cbc1884c657 Mon Sep 17 00:00:00 2001 From: Karl Kurbjun Date: Sun, 2 Aug 2009 07:05:30 +0000 Subject: Pluginlib: Add support for general buttons. Add menu and quit buttons to Reversi. MRobe 500: Modify touch handler to return the previous data always rather than 0 when there is no touch. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22110 a1c6a512-1295-4272-9138-f99709370657 --- apps/plugins/lib/SOURCES | 2 +- apps/plugins/lib/pluginlib_touchscreen.c | 249 +++++++++++++++++++++++++++++++ apps/plugins/lib/pluginlib_touchscreen.h | 117 +++++++++++++++ apps/plugins/lib/touchscreen.c | 135 ----------------- apps/plugins/lib/touchscreen.h | 94 ------------ 5 files changed, 367 insertions(+), 230 deletions(-) create mode 100644 apps/plugins/lib/pluginlib_touchscreen.c create mode 100644 apps/plugins/lib/pluginlib_touchscreen.h delete mode 100644 apps/plugins/lib/touchscreen.c delete mode 100644 apps/plugins/lib/touchscreen.h (limited to 'apps/plugins/lib') diff --git a/apps/plugins/lib/SOURCES b/apps/plugins/lib/SOURCES index 72538fc2a0..00d3ac7c56 100644 --- a/apps/plugins/lib/SOURCES +++ b/apps/plugins/lib/SOURCES @@ -54,7 +54,7 @@ pluginlib_albumart.c pluginlib_actions.c helper.c #ifdef HAVE_TOUCHSCREEN -touchscreen.c +pluginlib_touchscreen.c #endif md5.c diff --git a/apps/plugins/lib/pluginlib_touchscreen.c b/apps/plugins/lib/pluginlib_touchscreen.c new file mode 100644 index 0000000000..eb023b064c --- /dev/null +++ b/apps/plugins/lib/pluginlib_touchscreen.c @@ -0,0 +1,249 @@ +/*************************************************************************** +* __________ __ ___. +* Open \______ \ ____ ____ | | _\_ |__ _______ ___ +* Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / +* Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < +* Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ +* \/ \/ \/ \/ \/ +* $Id$ +* +* Copyright (C) 2008 by Maurus Cuelenaere +* Copyright (C) 2009 by Karl Kurbjun +* +* 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 software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY +* KIND, either express or implied. +* +****************************************************************************/ + +#include "plugin.h" + +#ifdef HAVE_TOUCHSCREEN + +#include "pluginlib_touchscreen.h" + +/******************************************************************************* + * Touchbutton functions: These functions allow the plugin to specify a button + * location that, in turn gets mapped to a button press return value. + ******************************************************************************/ + +/* touchbutton_get: + * This function checks the touchbutton structure passed to it for hits.
