We - will start by looking at how to scan for wifi access points, and how to - display and process this data in the application. At the end of the guide - we will show how to connect directly to a known wifi network configuration. - - \image wifi-cpp.jpg - - \section1 Listing Wifi Networks - - First we need to set up QListView widget which we will use to list wifi - networks that can be detected by the device. The detected network access - points are packed as a list-based data model and can be retrieved using - QWifiManager::networks. Here we also set a custom item delegate and - connect to two QWifiManager signals. - - \snippet wifi/wifi-cpp/main.cpp 0 - - \section1 Creating a Delegate - - The Wifi network model has many data roles that describe the different - properties of Wifi network. This data can be used by an application to list - detailed network information and/or to create QWifiConfiguration objects. - In this example we are interested in the network name. In the paint() - method we check if the network name is equal to the currently active - network connection, and append appropriate network state information. - - \snippet wifi/wifi-cpp/main.cpp 1 - - \section1 Connecting to a Selected Network - - On press of the \uicontrol Connect button, connetToNetwork() slot gets - invoked. In this slot we query network properties for the selected network - and create a QWifiConfiguration object, which we later pass to the - QWifiManager::connect function to set up a connection. During this - operation any changes in the network state is reported by QWifiManager - asynchronously. - - \snippet wifi/wifi-cpp/main.cpp 2 - - We use QWifiManager::NetworkState change event handler to trigger the - repainting of the delegate. This way, we can present a current network - state to the user. - - \snippet wifi/wifi-cpp/main.cpp 4 - - \section1 Connecting To a Known Network - - If you already know the network configuration beforehand, you can skip the - network scanning, listing and selection steps. This can be a valid use-case - for devices that do not change their physical location. - - QWifiManager::BackendState change events are reported asynchronously, so we - must connect the signal to a slot that connects to the network access point - after the backend initialization is complete. - - \snippet wifi/wifi-cpp/main.cpp 3 - */ diff --git a/examples/wifi/wifi-cpp/main.cpp b/examples/wifi/wifi-cpp/main.cpp deleted file mode 100644 index 54a35e9..0000000 --- a/examples/wifi/wifi-cpp/main.cpp +++ /dev/null @@ -1,228 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2014 Digia Plc -** All rights reserved. -** For any questions to Digia, please use the contact form at -** http://www.qt.io -** -** This file is part of Qt Enterprise Embedded. -** -** Licensees holding valid Qt Enterprise licenses may use this file in -** accordance with the Qt Enterprise License Agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and Digia. -** -** If you have questions regarding the use of this file, please use -** the contact form at http://www.qt.io -** -****************************************************************************/ -#include <QtCore> -#include <QtWidgets> -#include <B2QtWifi> - -class NetworkDelegate : public QStyledItemDelegate -{ - Q_OBJECT -//!
