Implement own lessThan(QVariant, QVariant)

Open olafmandel opened this issue 4 years ago • 0 comments

Qt 5.15 deprecated the operator<(QVariant, QVariant). Do get rid of the warning and to prepare for the eventual removal of the operator, implement our own needs in a lessThan() function.

The function is based on the description of QSortFilterProxyModel::lessThan().

Fixes #77
