QProgressDialog messes-up the setOverrideCursor

When setting the override cursor and using a QProgressDialog instance to perform dome action before resetting the override cursor, the QProgressDialog seems to reset the cursor shown to the normal arrow cursor and restoring the override cursor then sometimes fails. Result is that the wait cursor remains being shown.

In the QProgressDialog code, in the reset function there is a part at line 600 that might cause this

#ifndef QT_NO_CURSOR
    if (value() >= 0) {
        if (parentWidget())
            parentWidget()->setCursor(d->parentCursor);
    }
#endif

In here the private member parentCursor is being used but as far as I can see, this member is never being set. If this gets initialized with 0, it will reset the used cursor to the arrow cursor.

I now have to reset the override cursor before using the QProgressDialog and set it again after resetting it
