   // didn't work
QTextStream stream ( &file );
QString line;
QHash<QString, QString> variables;
while( !stream.eof() ) {
     line = stream.readLine();
     //Split
     QStringList splittedLine = line.split("=");
     //Maybe add some checks here (splittedLine.count == 2 etc.)
     variables.insert(splittedLine.at(0), splittedLine.at(1)); 
}
file.close();

Still need some help with this :-(

My code (mainwindow.cpp) looks now like this:

Code:

    QFile file("/etc/hildon/theme/colors.config");
    if (!file.open (IO_ReadOnly))
       // didn't work
    QTextStream stream ( &file );
    QString line;
    QHash<QString, QString> variables;
    while( !stream.eof() ) {
         line = stream.readLine();
         //Split
         QStringList splittedLine = line.split("=");
         //Maybe add some checks here (splittedLine.count == 2 etc.)
         variables.insert(splittedLine.at(0), splittedLine.at(1));
    }
    file.close();
    QString oldfont1 = variables.value(key.DefaultTextColor());

And build errors I get are:
'IO_ReadOnly' was not declared in this cope
'stream' was not declared in this scope
'key' was not declared in this scope

I propably didn't quite understand how QHash works so the last line of my code might be totally wrong too...
