Well then, derive a class from checked_widget that does _not_ change the colour but does ensure that the Ok,Apply buttons retain a "memory" of this invalid entry. As for "red", is this encoded in std::locale ? (Ok, ok, that was tongue in cheek!). More plausibly, we could easily define a "warning" lcolor and use that. -- Angus
