New signal slot syntax

kaivolde

Hi there,

I have a problem converting this statement:

connect( client, SIGNAL(error(QAbstractSocket::SocketError)),
            this, SLOT(onClientError(QAbstractSocket::SocketError)) );

to the new syntax. 'client' is a QTcpSocket.

I tried something like:

connect( client, &QTcpSocket::error,
             this, &MyServer::onClientError );

but I get an error: no matching member function for call to 'connect'

Can somebody help? Many thanks in advance.
Kai

Hi,

IIRC, QTcpSocket has two methods named error. You need to use qOverload to select the correct version.

And to add to @SGaist, the error() documentation describes how to do it.

Hi
Just as a note.
Often docs has sample when qOverload is needed
