QDoubleValidator

[gt.beta2]

Hello!
Showld't this lineEdit be accepting values from [0, 20] with one decimal?!

lineEdit->setValidator(new QDoubleValidator(0.0, 20.0, 1, this));

Thanks

Yes, it should.

Then i better take a good look because this lineEdit is accepting me values out of that range.
"I'll be back" :cool:

No, it is not. These are intermediate values because you can always write 200000E-5 to get 20. If you want the usual notation only, it is better to use a regexp validator:

new QRegExpValidator(QRegExp("\\d?\\d?(\\.\\d)?"), this);

or QDoubleSpinBox.

Yeah ... i was reading about this "limitation" a while ago.
Back to where i came from ... the RegExp :)

Thanks

It's not a limitation, it's an extension (or relaxation) :)
