How to convert pointer of qint8 to qstring ?

[dabla24]

Hi,
I need to get the string for value of qint8 which is stored in pointer?

// returns qint8*
@this->_vol@

I tried with
@QString volString = QString("0x%1").arg(this->_vol,0,16);@
or
@QString volString = QString::number(this->_vol);@
and
volString.setNum(this->_vol)
but I get every time no matching function

if _vol is a function you need to call it ( () ), and if it returns a pointer you need to dereference it ( * ). You don't need to type this-> every time. That's a given.
@
//assuming _vol is a member function:
QString volString = QString::number(*_vol());

//and if it's just a plain old data member:
QString volString = QString::number(*_vol);
