QList of float[20] throws error (typedef)

[Kevin470]

I have a couple of float arrays float[20] that I am trying to contain in a QList.
It works with the std::vector but does not compile when I try to contain them in a QList.
My code is so:

#include <vector>
#include <QList>

typedef float floatArray20[20];

class floatData
{
    floatData();
private:
    floatArray20 myarray1;
    floatArray20 myarray2;
    floatArray20 myarray3;
    
    QList<floatArray20> mylist;
//    std::vector<floatArray20> myVector;
    
};

If I make it so, I get the error:

In template: function cannot return array type 'QList<float[20]>::value_type' (aka 'float[20]')
qlist.h:528:5: error occurred here
in instantiation of template class 'QList<float[20]>' requested here

But it works perfectly fine with std::vector. What could be the mistake that I am doing?
Thanks.

@Kevin470 Did you try with std::array instead of plain C array?

@jsulm Thank you. That works. What could have been the problem? That C Arrays are not compatible for the container classes?
