From a94a2937323d90476779f50dee5fe99bf17ec0b9 Mon Sep 17 00:00:00 2001 From: thefiddler Date: Mon, 6 Jan 2014 14:25:05 +0100 Subject: [PATCH 01/15] [Platform] Implemented legacy IJoystickDriver LegacyJoystickDriver implements the legacy IJoystickDriver interface (GameWindow.Joysticks) in terms of the new IJoystickDriver2 interface (OpenTK.Input.Joystick). This removes a large chunk of code from each platform backend, as they no longer need to implement IJoystickDriver themselves. Additionally, it adds support for device hot plugging which was previously missing. --- Source/OpenTK/OpenTK.csproj | 1 + .../OpenTK/Platform/LegacyJoystickDriver.cs | 106 ++++++++++++++++++ 2 files changed, 107 insertions(+) create mode 100644 Source/OpenTK/Platform/LegacyJoystickDriver.cs diff --git a/Source/OpenTK/OpenTK.csproj b/Source/OpenTK/OpenTK.csproj index d9b969c9..b30dd262 100644 --- a/Source/OpenTK/OpenTK.csproj +++ b/Source/OpenTK/OpenTK.csproj @@ -798,6 +798,7 @@ + diff --git a/Source/OpenTK/Platform/LegacyJoystickDriver.cs b/Source/OpenTK/Platform/LegacyJoystickDriver.cs new file mode 100644 index 00000000..1f8e6c3e --- /dev/null +++ b/Source/OpenTK/Platform/LegacyJoystickDriver.cs @@ -0,0 +1,106 @@ +#region License +// +// LegacyJoystickDriver.cs +// +// Author: +// Stefanos A. +// +// Copyright (c) 2006-2014 Stefanos Apostolopoulos +// +// Permission is hereby granted, free of charge, to any person obtaining a copy +// of this software and associated documentation files (the "Software"), to deal +// in the Software without restriction, including without limitation the rights +// to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +// copies of the Software, and to permit persons to whom the Software is +// furnished to do so, subject to the following conditions: +// +// The above copyright notice and this permission notice shall be included in +// all copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
