    @MG33 I already told you what you're doing wrong. Just read it and act accordingly instead of repeating same information again and again. Accumulate data in a buffer until you got a complete package and then parse it and update your UI.

    @DrEmbo said in QNetworkInterface::addressEntries() returns empty list: allInterfaces this works for me with Qt 5.15.2 on Linux. QList< QNetworkInterface > network_interfaces = QNetworkInterface::allInterfaces(); for( auto interface : network_interfaces ) { if ( interface.flags().testFlag( QNetworkInterface::IsRunning ) ) { auto address_entries = interface.addressEntries(); for ( auto address_entry : address_entries ) { .................. } } }

    Hi author here, Now there's a dedicated guide available to follow for cross-compiling latest QT for any Raspberry Pi Model or Version with mentioned GCC toolchains: https://github.com/abhiTronix/raspberry-pi-cross-compilers/blob/master/QT_build_instructions.md

    You can use this app template: https://marketplace.qt.io/products/qt-lgpl-app-template Offers you a relink mechanism, also for embedded devices: you can release a redistributable project (your application inside a compiled static library, in a qt .pro project) and you must release your SDK (sysroot and compiler). If you use Static Qt, user can build his own Qt and rebuild your closed source application.

    Then one way would be to use QWebChannel.

    @adahl However when I tried to run it I get a complaint the file samba_conn_serial.dll could not be loaded, although the error message showed the complete path to that file and it was actually at that place. At first sight this seems very strange to me. Such errors could mean, that the DLL has own dependencies that are not satisfied. Dependency Walker is the tool of choice to debug that. Regardd

    Hi and welcome to devnet, There's no ready made "console widget", you can use QPlainTextEdit or depending on the amount of data a QListView with a custom QStyledItemDelegate for fancy rendering. For getting the output of your cli application, you can use QProcess.

    Hmm good catch! Although it turns out that I can't flick the list, because the items require some custom mouse move handling ... which reduces it to a non-interactive PathView. So, solved I guess! Thanks for pointing out the Tumbler though, and I hope my examples prove to be useful to others.
