Member Function Documentation

[private signal, deprecated] void QSocketNotifier::activated(int socket)

This function is deprecated. We strongly advise against using it in new code.

To avoid unintended truncation of the descriptor, use the QSocketDescriptor overload of this function. If you need compatibility with versions older than 5.15 you need to change the slot to accept qintptr if it currently accepts an int, and then connect using Functor-Based Connection.

This signal is emitted whenever the socket notifier is enabled and a socket event corresponding to its type occurs.

The socket identifier is passed in the socket parameter.

Note: Signal activated is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:

connect(socketNotifier, QOverload<int>::of(&QSocketNotifier::activated),
    [=](int socket){ /* ... */ });
