Perform an unconditional conversion to string and sort that. In a model, where you're likely to *display* the element, this is probably the right thing to do, as you don't want to explain to your users why your list shows items like 1 10 11 2 3 21 A few of the above are strings and the others are numbers. It should always lexicographically sort or use numeric/natural sorting. > Maybe making QAbstractItemModelPrivate::isVariantLessThan public and clearly > defining what it was would be good enough (i mean if it is good enough for > QAbstractItemModel it could be enough for most of the other > implementations). That's a good idea. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel DPG Cloud Engineering _______________________________________________ Development mailing list [email protected] https://lists.qt-project.org/listinfo/development
