QT4.2.2 and QTcpSocket

[camel]

Hello,

I had several problems using the QTcpSocket, and I can't find examples of code that use the QTcpSocket in order to access a server with IMAP.
Do you have a sample code, please ?

I have non for imap, but there are a lot if QTcpSocket examples in the Trolltech documentation.

Or just google a bit. I found for example mailody, an KDE-Imap client.
Or search via Google Codesearch.
A simple search produced for example this file which seems to be an inbox checker for imap written in Qt.

Just remember, if you let yourself inspire by other code...honor the license and do not copy code...unless allowed by the license of course :-)

Or, perhaps, do you know where to find more informations ?

On what? QTcpSocket? Best use the Trolltech docs ;-)
IMAP? Check the RFC?

PS : The following code throws me stranges errors :
- "undefined reference to _imp___ZN10QTcpSocketC1EP7QObject"

Do you use qmake?
Add "QT += network" to you pro file. It looks as if the network lib is not linked to your app.

Thanks a lot !

The "QT += network" doesn't make anything better
Perhaps my Qt installation is bad... I'll try to see it.

Google Code Search is too usefull !
It's the first time I hear baout it, thanks !

Sorry if I let think that I didn't search a lot, but my QtAssistant doesn't display me the file and I didn't know Google Code Search... So it was a bit difficult

That's why I mentioned it...how does this old proverb go...

Give a man a fish, and he will eat for a day,
Teach a man to fish, and he will eat for a lifetime.

Regarding your linking problem, I sadly have no idea what it could be...probably someone else does though :-)

I was able to compile the following code:

#include <QTcpSocket>
#include <QApplication>
 
int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
	QTcpSocket * socket = new QTcpSocket();
	socket->connectToHost("imap.free.fr", 143);
	return app.exec();
}

#include <QTcpSocket>
#include <QApplication>

int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
	QTcpSocket * socket = new QTcpSocket();
	socket->connectToHost("imap.free.fr", 143);
	return app.exec();
}

Thanks, the error was that my "qpake -project" doesn't add "QT += network" to my .pro file.

I don't know how to solve that problem, but now I know that I can use the Sockets

Well, you only use qmake -project once (at least that is what it is intendet for from what I gather), and from then on you simply modify the ".pro" file by hand.

The project file that qmake return is just a very rudimentary thing, and the .pro syntax is not too hard :-)

From command-line:

qmake -project "QT = core gui network"

qmake -project "QT = core gui network"
