Код:

connect(& pClientSoket,SIGNAL(pClientSoket::disconnected),& pClientSoket,SLOT(pClientSoket::deleteLater));

ошибка: no matching member function for call to 'connect'

помогите пожалуйста

[kambala]

надо писать либо

Код

C++ (Qt)
connect(&pClientSoket, SIGNAL(disconnected()), &pClientSoket, SLOT(deleteLater()));

либо

Код

C++ (Qt)
connect(&pClientSoket, &QTcpSocket::disconnected, &pClientSoket, &QTcpSocket::deleteLater);

[Noize_programmer]

если пишу это

Код:

    connect(&pClientSoket, SIGNAL(disconnected()), &pClientSoket, SLOT(deleteLater()));

то ошибка:
ошибка: no matching member function for call to 'connect'

а если пишу это

Код:

        connect(&pClientSoket, &QTcpSocket::disconnected, &pClientSoket, &QTcpSocket::deleteLater);

то ошибки:
ошибка: no matching member function for call to 'connect'

полная ошибка всегда пишется во вкладке номер 4, без нее ничего не понятно

а, так pClientSoket у тебя уже и так указатель, тогда не надо перед ним ставить &

вот почему надо сразу давать максимальную информацию о коде

огромное сапсибо за помощь!

p.s.
впредь буду давать больше информации о коде

(я пошёл писать TCP Client)
