You may store it as a void pointer.

Example:
koffice/kspread/ui/View.cpp:1909:
    // Let the selection pointer become a canvas resource.
    QVariant variant;
    variant.setValue<void*>( d->selection );
    d->canvas->resourceProvider()->setResource( Canvas::Selection, variant );

koffice/kspread/chart/ChartDatabaseSelector.cpp:86:
    d->selection = 
static_cast<Selection*>(m_resourceProvider->resource(Canvas::Selection).value<void*>());

Stefan
