From 4bec2216312c231b2082f0b462328b1270b00836 Mon Sep 17 00:00:00 2001 From: "Bradley T. Hughes" Date: Tue, 27 Jul 2010 09:46:09 +0200 Subject: Add multicastsender and multicastreceiver examples These are clones of the broadcastsender and broadcastreceiver examples, modified to use the multicast API. I've made sure that the examples are linked in the appropriate places as well. --- doc/src/examples/multicastreceiver.qdoc | 36 +++++++++ doc/src/examples/multicastsender.qdoc | 36 +++++++++ doc/src/getting-started/examples.qdoc | 2 + doc/src/network-programming/qtnetwork.qdoc | 9 ++- examples/network/multicastreceiver/main.cpp | 51 +++++++++++++ .../multicastreceiver/multicastreceiver.pro | 12 +++ examples/network/multicastreceiver/receiver.cpp | 84 ++++++++++++++++++++ examples/network/multicastreceiver/receiver.h | 70 +++++++++++++++++ examples/network/multicastsender/main.cpp | 51 +++++++++++++ .../network/multicastsender/multicastsender.pro | 12 +++ examples/network/multicastsender/sender.cpp | 89 ++++++++++++++++++++++ examples/network/multicastsender/sender.h | 77 +++++++++++++++++++ examples/network/network.pro | 4 +- src/network/socket/qudpsocket.cpp | 8 +- 14 files changed, 535 insertions(+), 6 deletions(-) create mode 100644 doc/src/examples/multicastreceiver.qdoc create mode 100644 doc/src/examples/multicastsender.qdoc create mode 100644 examples/network/multicastreceiver/main.cpp create mode 100644 examples/network/multicastreceiver/multicastreceiver.pro create mode 100644 examples/network/multicastreceiver/receiver.cpp create mode 100644 examples/network/multicastreceiver/receiver.h create mode 100644 examples/network/multicastsender/main.cpp create mode 100644 examples/network/multicastsender/multicastsender.pro create mode 100644 examples/network/multicastsender/sender.cpp create mode 100644 examples/network/multicastsender/sender.h diff --git a/doc/src/examples/multicastreceiver.qdoc b/doc/src/examples/multicastreceiver.qdoc new file mode 100644 index 0000000..f769705 --- /dev/null +++ b/doc/src/examples/multicastreceiver.qdoc @@ -0,0 +1,36 @@ +/**************************************************************************** +** +** Copyright (C) 2010 Nokia Corporation and/or its subsidiary(-ies). +** All rights reserved. +** Contact: Nokia Corporation (qt-info@nokia.com) +** +** This file is part of the documentation of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:FDL$ +** Commercial Usage +** Licensees holding valid Qt Commercial licenses may use this file in +** accordance with the Qt Commercial License Agreement provided with the +** Software or, alternatively, in accordance with the terms contained in a +** written agreement between you and Nokia. +** +** GNU Free Documentation License +** Alternatively, this file may be used under the terms of the GNU Free +** Documentation License version 1.3 as published by the Free Software +** Foundation and appearing in the file included in the packaging of this +** file. +** +** If you have questions regarding the use of this file, please contact +** Nokia at qt-info@nokia.com. +** $QT_END_LICENSE$ +** +****************************************************************************/ + +/*!
