Qt has the portable type quintptr just for this.  From the Qt docs:

"Integral type for representing a pointers (useful for hashing, etc.).

Typedef for either quint32 or quint64. This type is guaranteed to be the
same size as a pointer on all platforms supported by Qt. On a system
with 32-bit pointers, quintptr is a typedef for quint32; on a system
with 64-bit pointers, quintptr is a typedef for quint64.

Note that quintptr is unsigned. Use qptrdiff for signed values."
