Error on use QTcpServer

[prchakal]

Hi ppl,

Im trying make a TcpServer with QTcpServer, but i get a error. Im follow this example:

http://qt.nokia.com/doc/4.6/network-fortuneserver.html

I get the errors:



"tcpServerConnection" is declared on header as "QTcpSocket *tcpServerConnection".

If i comment the line where i get the error it compile normal:
"connect(tcpServerConnection, SIGNAL(disconnected()), tcpServerConnection, SLOT(deleteLater()));"

The problem is when i try use the object "tcpServerConnection".

I cant do anything with it that i get an error and the code complete doesnt work when i try:
"tcpServerConnection->"

The fortune server example works fine, but mine not o.o

My guess is that your defined ServerDialog::connect(...) and now C++ compiler are not able to decide, which method you are trying to call. Use fully qualified name:

QObject::connect(tcpServerConnection, SIGNAL(disconnected()), tcpServerConnection, SLOT(deleteLater()));

Hi man.

I got the same error:



Im using QT 4.6 and QT Creator 1.3

Then it's time to share your sample code.

Problem solved, i forgot put:

#include <QTcpSocket>

On the header file.

Thx.

Strange. In my understanding in such a case you should have other build errors before QObject::connect. But good that this is resolved now.

Problem solved, i forgot put:

#include <QTcpSocket>

On the header file.

Thx.

The explanation why this is the only error is that QTcpSocket was forward declared and the only thing the compiler needs to know from the header file is that QTcpSocket somehow inherits QObject.
