true representation in binary or hex

[wysota]

Hi,

but then what value sends

QByteArray ba;
QDataStream out(&ba, QIODevice::WriteOnly);
out << true;
clientConnection->write(ba);

QByteArray ba;
QDataStream out(&ba, QIODevice::WriteOnly);
out << true;
clientConnection->write(ba);

To copy to clipboard, switch view to plain text mode 

Run the program and see for yourself.

how simulate boolean value true,

I don't know what you mean by "simulate" in this context.

how it would look in binary?

true (as a C++ keyword) is usually interpreted as 0x01.

How to achieve the same result without true?

I have no idea what you mean.
