- \title Getting Started with B2Qt.Wifi in C++
- \example wifi/wifi-cpp
- \ingroup wifi-examples
- \brief Guide to getting started with B2Qt.Wifi using C++.
- \section1 Preparing the Application
- Use the following \c include statement to access the C++ classes:
- \code
- #include <B2QtWifi>
- \endcode
- Before building your application, add the following statement to your
- \c .pro file to link against the B2Qt.Wifi library:
- \code
- QT += b2qtwifi
- \endcode
- This guide will demonstrate how to create a Qt Widget-based application
- that utilizes the B2Qt.Wifi API to set up a wifi network connection. 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.

- \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.

- \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.

- \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.

- \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.
