I am trying to display a number using QDebug in the Hex format. Below is the code which I have written. It is working but the output has string contents enclosed in double quotes:

How to remove these quotes?

m_CanMsg_ptr->id = 0x720;
m_CanMsg_ptr->sizeData = 1;
m_CanMsg_ptr->data[0] = 0x05;

MessageID.setNum(m_CanMsg_ptr->id,16);
DataSize  = QString("%1").arg(m_CanMsg_ptr->sizeData, 0, 16);
data      = QString("%1").arg(m_CanMsg_ptr->data[0], 0, 16)

qDebug() << "Heart-Beat : Msg ID = " << MessageID << "  Msg DLC = " << DataSize;
qDebug() << "Msg Data " << " = " << data;

I did as per these resources:

The solution is simple:

#include <QDebug>

int value = 0x12345;
qDebug() << "Value : " << hex << value;
