    Default sorting problem in QSetting set.allkeys() ??

    i want to read some db names from a config file and they are ordered.
    but when i read them with allkeys , the data that i have now is sorted by allkeys!
    what can i do ?

    Qt Code:
    1. //for example
    2. QSettings settings;
    3. settings.setValue("a", Qt::white);
    4. settings.setValue("c", QSize(32, 96));
    5. settings.setValue("b", true);
    6. settings.setValue("d", false);
    7.  
    8. QStringList keys = settings.allKeys();
    9. //instead of a c b d i have a b c d !!
    To copy to clipboard, switch view to plain text mode 

    but i need a c b d ???
    any idea.

    thanks

    I'm afraid you can't AND you shouldn't rely on the order settings are saved. As you know, the storage behind QSettings might be an INI file, XML preferences file or Windows registry. I'd suggest adjusting your design not to care about the order...

    i use this way ! so orders can take place by %Number
    %01
    %00
    %02

    when i write to config :setting.setValue("/Database/"+dbName.prepend(row)); %01Name
    when i read from config :dbnames.at(row).remove(0,1) Give Me Name
