what's wrong with my validator?

AFAIR QDoubleValidator permits the "scientific" notation, so you can write 1000000e-4 or -99999999e-5.

Jacek is correct. If you don't need scientific notation, you can better achieve what you want with a regular expression validator:

setValidator(new QRegExpValidator(QRegExp("[-+]?[0-9]{0,3}(\\.[0-9]{0,2})"), LineEdit));

setValidator(new QRegExpValidator(QRegExp("[-+]?[0-9]{0,3}(\\.[0-9]{0,2})"), LineEdit));

Yes, of course, RegEx.
just one thing though: at compile time I don't know what my min, max are.
Still, no way around that without the work - I'll have convert my max to a string parse it and build my RegEx. Or validate by hand as suggested.

Thanks guys,
