示例1: handleStateChanged

/* Qt delivers the stateChanged() signal before the error() one.
That's a problem because we really want to provide a nice error message
to the user and QAbstractSocket::error() is not set yet by the time this
function executes. That's why we have to delay the first disconnected() signal. */
