Obsolete Members for QWebSocket
类QWebSocket 的以下成员已被弃用。提供这些成员是为了保持旧源代码的正常运行。我们强烈建议不要在新代码中使用它们。
信号
(deprecated in 6.5) void | error(QAbstractSocket::SocketError error) |
成员函数文档
[signal, deprecated in 6.5] void QWebSocket::error(QAbstractSocket::SocketError error)
自 6.5 版起，该函数已被弃用。我们强烈建议不要在新代码中使用该函数。
请使用errorOccurred(QAbstractSocket::SocketError error) 代替它。
注意：该类重载了error信号。要使用函数指针语法连接到该信号，Qt 提供了一个方便的辅助工具来获取函数指针，如本例所示：
connect(webSocket, QOverload<QAbstractSocket::SocketError>::of(&QWebSocket::error), [=](QAbstractSocket::SocketError error){ /* ... */ });
