The document provides a sample Qt application code for selecting a Wi-Fi network card and its associated hotspots using QNetworkInterface and QNetworkConfigurationManager. It creates a UI with two combo boxes: one for network cards and another for hotspots, populating them based on available interfaces and configurations. The application updates the hotspot options dynamically based on the selected network card and handles configuration changes.

To select a Wi-Fi network card and its hotspot in a Qt UI, you can use the QNetworkInterface and QNetworkConfigurationManager classes provided by the Qt library. Here's a sample code that demonstrates how to achieve this:
 
In this code, we create a Qt application with a main window that contains a vertical layout. The layout holds two combo boxes: networkCardComboBox for selecting the network card, and hotspotComboBox for selecting the Wi-Fi hotspot.
We use QNetworkInterface::allInterfaces() to retrieve a list of network interfaces (network cards), filter out the loopback and non-up interfaces, and populate the networkCardComboBox with the human-readable names of the network cards.
We create a QNetworkConfigurationManager to manage network configurations. We connect its configurationChanged signal to a lambda function that updates the hotspotComboBox whenever the network configuration changes. The lambda function filters out the WLAN configurations for the selected network interface and adds them to the hotspotComboBox.
We also connect the currentIndexChanged signal of the networkCardComboBox to update the hotspotComboBox when the selection changes. This ensures that the available hotspots are updated based on the selected network card.
By running this code, you should see a window with two combo boxes. The first combo box lists available network cards, and the second combo box displays the available hotspots based on the selected network card.
Please note that the behavior of the QNetworkConfigurationManager can vary across different platforms and configurations. It's important to test the code on your target platform and handle any specific requirements or error conditions accordingly.
