    I think it's a style issue as explained here: https://doc.qt.io/qt-6/stylesheet.html "For example, it might be tempting to set the QPalette::Button role to red for a QPushButton to obtain a red push button. However, this wasn't guaranteed to work for all styles, because style authors are restricted by the different platforms' guidelines and (on Windows and macOS) by the native theme engine." Which OS & Qt style do you use?

    Please check the return values of the sqlquery functions - esp. QSqlQuery::prepare() and check that the two column names are really available.

    I have found the problem... I have called: file->open(QIODevice::ReadOnly | QIODevice::Text) while the file I am reading is not Text, opening the file simply via: file->open(QIODevice::ReadOnly) fixed it.

    Thank you ! setDetailledText() shows both the text, and a button to see the text in a scrolling area. So it helps, but I would prefer to have directly, and only, the scrolling area.

    @JonB @JonB said in QSettings doesn't save data: I guess the event loop does not get to run, nor does QSettings object get destructed, I thought this could be the problem. @JonB said in QSettings doesn't save data: Put in an explicit QSettings::sync() after setOnPowerFail() before restart, does that fix? Actually yes, it did it!
