initilization of QScopedPointer

[weaver4]

I have a empty QScopedPointer defined in a header.

QScopedPointer<HardwareInterface> hwi;

QScopedPointer<HardwareInterface> hwi;

To copy to clipboard, switch view to plain text mode 

I know that I can initilize it doing this in my class.

MainClass::MainClass(QObject *parent) :
    QObject(parent), hwi(new HardwareInterface())
{
}

MainClass::MainClass(QObject *parent) :
    QObject(parent), hwi(new HardwareInterface())
{
}

To copy to clipboard, switch view to plain text mode 

But is there another way to do it in the main-line of the code? For example maybe I need to get the values of parameters before I init it.

I have tried this,

hwi = QScopedPointer<HardwareInterface>(new HardwareInterface());

hwi = QScopedPointer<HardwareInterface>(new HardwareInterface());

To copy to clipboard, switch view to plain text mode 

but I get this error:

/home/trey/Qt5.2.1/5.2.1/gcc_64/include/QtCore/qglobal.h:979: error: 'QScopedPointer<T, Cleanup>& QScopedPointer<T, Cleanup>::operator=(const QScopedPointer<T, Cleanup>&) [with T = HardwareInterface; Cleanup = QScopedPointerDeleter<HardwareInterface>]' is private
     Class &operator=(const Class &) Q_DECL_EQ_DELETE;
            ^

whatever that means.

You can set the pointer after initialization using the reset method.

Or use a QSharedPointer.

thanks!

I guess I should of looked for something that took a pointer and returned a QScopedPointer.
