+ SDLGamepad
+ 1.0
+
+---
+
+This is the SDLGamepad library, used to receive gamepad activity from
+a SDL supported gamepad.
+
+SDLGamepad is written in C++ with the QT bindings backing it up. It
+is was tested on Windows XP, Windows Vista 32/64 bit,
+Windows 7 32/64 bit, Mac OSX, Ubuntu 32/64 bit. The SDL Framework is
+used to get gamepad input, so you need a working SDL Framework install
+on your system! For more information see www.libsdl.org
+
+This program is distributed under GNU LGPL version 3, which can be
+found in the file "COPYING". This license allows you to use
+tank-gamepad freely in commercial programs.
+
+Enjoy!

+ * documentation is inside the header file.
+ *
+ */
+
+/*!
+ * @mainpage SDLGamepad API Documentation
+ *
+ * @section intro_sec Introduction
+ *
+ *
+ * This is the API Documentation for the SDLGamepad library.
+ *
+ *
+ *
+ * This library makes use of the SDL-1.2 library to send / receive
+ * information from a gamepad / joystick that is compatible with the
+ * SDL system. It is written in QT. Because of the fact that SDL and QT
+ * are avaliable on many platforms you can use this library on every
+ * platform that supports SDL and qt!
+ *
+ *
+ * @section install_sec Installation
+ *
+ * @subsection step1 Step 1: Requirements
+ *
+ *
+ * You need a QT 4.5.x and SDL-1.2 to compile this library.
+ *
+ *
+ *
+ * For further information check http://qt.nokia.com and
+ * http://www.libsdl.org
+ *
+ *
+ * @subsection step2 Step 2: Getting the code..
+ *
+ *
+ * You can get the source code via svn:
+ * svn co http://www.nalla.de/svn/tank/sdlgamepad/trunk
+ * sdlgamepad
+ *
+ *
+ * @subsection step3 Step 3: Compile the code!
+ *
+ *
+ * If you want debug information you should run:
+ *
+ *
+ *
+ * qmake CONFIG+=debug
+ * make
+ *
+ *
+ *
+ * You should now have .so files or a .dll file in the build
+ * subdirectory.
+ *
+ *
+ *
+ * For a release build just run qmake without the CONFIG+=debug!
+ *
+ *
+ * @section add_sec Additional information
+ *
+ *
+ * You need to have SDL installed globally in the mingw directory on
+ * windows. This is due to the fact that on unix systems sdl is mostly
+ * in the distributions repository system avaliable and therefore a
+ * global install.
+ *
+ *
+ * @section ex_sec Implemention example
+ *
+ * @code
+ * #include
+ * #include
+ * #include "otherclass.h"
+ * #include "sdlgamepad.h"
+ *
+ * int main(int argc, char *argv[])
+ * {
+ * QCoreApplication a(argc, argv);
+ * OtherClass other;
+ * SDLGamepad sdl;
+ *
+ * a.connect(&a, SIGNAL(aboutToQuit()), &sdl, SLOT(quit()));
+ *
+ * if(sdl.init())
+ * {
+ * sdl.start();
+ * qRegisterMetaType("QListInt16");
+ * qRegisterMetaType("ButtonNumber");
+ *
+ * a.connect(&sdl, SIGNAL(axesValues(QListInt16)),
+ * &other, SLOT(someSlot(QListInt16)));
+ * a.connect(&sdl, SIGNAL(buttonState(ButtonNumber, bool)),
+ * &other, SLOT(someOtherSlot(ButtonNumber, bool)));
+ *
+ * return a.exec();
+ * }
+ *
+ * qFatal("Init of SDLGamepad failed! Shutting down..");
+ * a.exit();
