QByteArray to QString

[rz]

I Use QTcpServer to read QbyteArray

while ( client->bytesAvailable() > 0) {
buffer += client->readAll();
}

this code above work fine
but i need convert this data to QString
I receive this "|\0000\0000\0001\000|\000|\0009\0009\0009\000|\000" (bin data) use QString line = QString::fromAscii(buffer,buffer.size()); or QString line = QString::fromUTF8(buffer,buffer.size());

bu i Need transparent value like
this
|001||999|

how can I do it ?
