From 224f31c0b5ad86b5ea56025ff08faf7e25e1a82d Mon Sep 17 00:00:00 2001 From: Dominik Holland Date: Thu, 24 Mar 2016 15:38:05 +0100 Subject: Multi-screen handling for the eglfs_kms_egldevice backend Separates the generic kms classes into a own kms static lib called QtEglFsKmsSupport. The eglfs_kms plugin was changed to use these base classes and got renamed accordingly to QEglFSKmsGbm*. The eglfs_kms_egldevice plugin got extended to also derive from the kms base classed and by this provides multi-screen support Change-Id: I6de6a754e94cb8d52cf8e658b03c6bd6637674a1 Reviewed-by: Laszlo Agocs --- .../eglfs_kms_support/qeglfskmsdevice.h | 98 ++++++++++++++++++++++ 1 file changed, 98 insertions(+) create mode 100644 src/plugins/platforms/eglfs/deviceintegration/eglfs_kms_support/qeglfskmsdevice.h (limited to 'src/plugins/platforms/eglfs/deviceintegration/eglfs_kms_support/qeglfskmsdevice.h') diff --git a/src/plugins/platforms/eglfs/deviceintegration/eglfs_kms_support/qeglfskmsdevice.h b/src/plugins/platforms/eglfs/deviceintegration/eglfs_kms_support/qeglfskmsdevice.h new file mode 100644 index 0000000000..ffa8bcbaa5 --- /dev/null +++ b/src/plugins/platforms/eglfs/deviceintegration/eglfs_kms_support/qeglfskmsdevice.h @@ -0,0 +1,98 @@ +/**************************************************************************** +** +** Copyright (C) 2015 Pier Luigi Fiorini +** Copyright (C) 2016 The Qt Company Ltd. +** Copyright (C) 2016 Pelagicore AG +** Contact: https://www.qt.io/licensing/ +** +** This file is part of the plugins of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:LGPL$ +** Commercial License Usage +** Licensees holding valid commercial Qt licenses may use this file in +** accordance with the commercial license agreement provided with the +** Software or, alternatively, in accordance with the terms contained in +** a written agreement between you and The Qt Company.
