Dynamically typed container in Qt

Question

Is there a container who can store different types (yes, I really need to work with different kind of types) in Qt? I must create a new class to do this? If so, could you give me a hint to create it?

Answer 1

1. Most of containers in Qt are template based, then you can use them for different static types.

2. Another option is to use use QVariant, for example: QVector<QVariant> vec;.

3. A more dynamic solution is to use polymorphism, you can store pointers to a base class and so on.. .
