QTcpSocket

[hkaraoguz84]

Hi, can someone help me with this code?
I don't know if it connects or anything it just doesnt write anything to the "QTextEdit* read"
mainwindow.h

connect(write, SIGNAL(textChanged(const QString&)), this, SLOT(sendMessage()));
}

connect(write, SIGNAL(textChanged(const QString&)), this, SLOT(sendMessage()));
}

To copy to clipboard, switch view to plain text mode 

Hi,

This part is problemmatic I guess. The signal and corresponding slot should have the same arguments. The connection should be like

connect(write, SIGNAL(textChanged(QString)), this, SLOT(sendMessage(QString)));

connect(write, SIGNAL(textChanged(QString)), this, SLOT(sendMessage(QString)));

To copy to clipboard, switch view to plain text mode 

Your slot should be declared as

void sendMessage(const QString& dummy)

I hope this solves your problem.

The reason you cannot type to "TextEdit* read" is

read->setReadOnly(true);

read->setReadOnly(true);

To copy to clipboard, switch view to plain text mode 

if you change the argument to "false", you will be able to write in the "read".

my problem is that im not receiving anything from the socket & i need to be able to receive & send, this function:

void MainWindow::appendToWindow()
{
	char buffer[1024];
	while(socket->canReadLine()) {
		socket->readLine(buffer, sizeof(buffer));
		read->append(buffer);
	}
}

void MainWindow::appendToWindow()
{
	char buffer[1024];
	while(socket->canReadLine()) {
		socket->readLine(buffer, sizeof(buffer));
		read->append(buffer);
	}
}

i don't want to write here, this text edit is for receiving data from the socket ;/

edit:
i made something like this:

if(socket->waitForConnected(-1) == true)
		read->append("Connected.");
	else
		read->append(socket->errorString());

if(socket->waitForConnected(-1) == true)
		read->append("Connected.");
	else
		read->append(socket->errorString());

it gave me this:

Socket operation timed out

Socket operation timed out

The textChanged signal is fired every time you press a key. This might not be the behaviour you want.

Use the readyRead() signal of the socket and connect it to your appendToWindow() slot.

By the way, if a socket times out, that's in most cases not a problem with your code.
