convert an int to QByteArray in Qt

Question

I'm trying to convert an int to QByteArray. I'm using this method QByteArray::number(m_vman); is it correct?

I'm trying to use the number() for getting an int to QByteArray.

I'm trying the following code but the bytearray is zero

    QByteArray vmanByteArray, vheaterByteArray;
    QDataStream streamVMan(&vmanByteArray, QIODevice::WriteOnly);
    QDataStream streamVHeater(&vheaterByteArray, QIODevice::WriteOnly);

    streamVMan << m_vman;
    streamVHeater << m_vheater;

QByteArray arr = m_htman ? vmanByteArray : vheaterByteArray;

Answer 1

you can simply do like this.

int myInt = 123;
QByteArray q_b;
q_b.setNum(myInt);

Answer 2

Related to the actual question title, the following static function should definitely work:

QByteArray::number
