When I run the app, it creates the sandbox directory just fine, however QSettings never creates the settings file. I am using QSettings at its most basic form, that is I create the settings object like so:

Quick follow-up: This is apparently not an issue with an incorrect path in QSettings or with the app not having write privileges to the specified directory. I added the following code immediately after declaring the QSettings object:

    QFile prefsFile(settings.fileName());
    if(!prefsFile.exists()){
        prefsFile.open(QIODevice::WriteOnly); //try to create the settings file
        prefsFile.close();
    }

...and it works. The file is created, and after that I can set and retrieve settings as expected. This is quite the ugly workaround, however - QSettings should be creating the file if needed already. So at least I have a workaround that *appears* to be functional, but it would be nice to know why this is happening and how to *properly* fix it. Thanks.
