You don't need to copy the QPointer. A QPointer is a weak pointer class.
It is told by the object it holds, if it's deleted, and then switch to a
null pointer.
So in your case, you simply give the object it holds to your function
instead.
If you want to, you can create a QPointer in your function.
void myFunction(QObject* o) {
QPointer p(o);
// do something
}
QPointer p(theRealObject);
myFunction(p.data());
I hope this helps.
Bo.
