This is the required change

You do not need to change every reference. See the following example from
http://doc.qt.io/qt-4.8/qpointer.html

code without QPointer

   QLabel* label = new QLabel;
    label->setText("&Status:");
    ...
    if (label)
        label->show();

code with QPointer: 

   QPointer<QLabel> label = new QLabel;
    label->setText("&Status:");
    ...
    if (label)
        label->show();

It is only required to change the definition and mostly references should work
out of the box.
