switch/case statement in C++ with a QString type

Question

I want to use switch-case in my program but the compiler gives me this error:

switch expression of type \'QString\' is illegal

How can I us

Answer 1

As previously noted this is not a Qt problem, switch statements can only use constant expressions, look at the collection classes a QSet is a good solution

void initStopQwords(QSet& stopSet)
{
    // Ideally you want to read these from a file
    stopSet << "the";
    stopSet << "at";
    ...

}

bool isStopWord(const QSet& stopSet, const QString& word)
{
    return stopSet.contains(word);
}
