copying a std::vector to a qvector

Question

I tried copy content of one vector to a QVector using the following

std::copy(source.begin(), source.end(), dest.begin());

However the destination QVector still is empty.

Any suggestions ?

Answer 1

Look at:

std::vector<T> QVector::toStdVector () const

QVector<T> QVector::fromStdVector ( const std::vector<T> & vector ) [static]

From docs

Answer 2

If you are creating a new QVector with the contents of a std::vector you can use the following code as an example:

   std::vector<T> stdVec;
   QVector<T> qVec = QVector<T>::fromStdVector(stdVec);
