From 9e3af4a3a828a0c632ef07969005f46fd30bee63 Mon Sep 17 00:00:00 2001 From: Andre Hartmann Date: Thu, 28 Apr 2016 09:02:51 +0200 Subject: CAN-Example: Change SettingsDialog to ConnectDialog This simplifies the handling and makes it more like how other CAN monitors behave. * After startup, the connect dialog is shown * If the dialog is accepted, the selected device is connected instantly * To interrupt a connection, the disconnect action can be used * To connect again, the action connect can be used Change-Id: I47db596658e90cc0393981fba135cd6d89191f1a Reviewed-by: Alex Blasche --- examples/serialbus/can/connectdialog.cpp | 244 +++++++++++++++++++++++++++++++ 1 file changed, 244 insertions(+) create mode 100644 examples/serialbus/can/connectdialog.cpp (limited to 'examples/serialbus/can/connectdialog.cpp') diff --git a/examples/serialbus/can/connectdialog.cpp b/examples/serialbus/can/connectdialog.cpp new file mode 100644 index 0000000..7495832 --- /dev/null +++ b/examples/serialbus/can/connectdialog.cpp @@ -0,0 +1,244 @@ +/**************************************************************************** +** +** Copyright (C) 2015 The Qt Company Ltd. +** Contact: http://www.qt.io/licensing/ +** +** This file is part of the examples of the QtSerialBus module. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of The Qt Company Ltd nor the names of its +** contributors may be used to endorse or promote products derived +** from this software without specific prior written permission. +** +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.
