struct: constructor/destructor for fixing C2280 error: attempting to reference a deleted function

[sitesv]

Hello!
I got a C2280 error with next code:

struct my_struct{
    QTcpSocket sock;
};
std::vector<my_struct> my_vector;

int main(int argc, char *argv[]){
    QCoreApplication a(argc, argv);
    for(int i = 0; i < 10; i++){
        my_struct mtca;
        my_vector.push_back(mtca);
    }
    return a.exec();
}

There is an error with the copying objects to the vector.
I got the same error when using a QMutex in this struct.
As I understood, I need to use pointers.

struct my_struct{
    QTcpSocket *sock = nullptr;
    my_struct(){
        sock = new QTcpSocket;
    }
};
std::vector<my_struct> my_vector;
int main(int argc, char *argv[]){
    QCoreApplication a(argc, argv);
    for(int i = 0; i < 10; i++){
        my_struct mtca;
        my_vector.push_back(mtca);
    }
    return a.exec();
}

How to work correctly with a dynamic creation and destroying objects in the structs?
Thank you!

QObjects can not be copied. Use a pointer (or smart pointer) in your struct.

Hi
Anything that inherits QObject cannot be copied as that would make signal and slot go amok.

So easy fix is to use pointers to such members

struct my_struct {
    QTcpSocket *sock;
    my_struct() : sock(new QTcpSocket ) {}  // let constructor allocate it.
    ~my_struct()
    {
        sock->deleteLater();   // remember to deallocate it
    }
};

oh Mr Ehrlicher beat me to it :)
