Qt. How to define a static QStringList?

Question

Qt

This is how it doesn't work:

class MyClass
{
private:
    static QStringList MyString;
};

QStringList MyClass::MyString << "1" << "2" << "3";

This also doesn't work:
QStringList MyClass::MyString = { "1", "2", "3" };

Answer 1

QStringList MyClass::MyString = { "1", "2", "3" };
