QRegExp for strings with numbers

Hi!

I need a regexp which accepts a string (maximum 30 characters/Slots) with:

- letters from A to Z (not Á or Ñ or Ë...)
- numbers
- spaces
- signs: . , -

No matter the order so valid examples are :

- Hello how are you
- Hi. My -name- is ... mm

I was trying with that but it just accepts letters and numbers:

Code:

---

QRegExp rx7("[A-Z0-9]{0,30}");
    QValidator *validator7 = new QRegExpValidator(rx7, this);
    myLineEdit->setValidator(validator7);

---

Thank you so much

It only accepts letters and numbers because that's what your regexp contains. You have to put the remaining allowed characters in the selector as well.

Hi wysota,

Yes I knwo but I don't know how to put dot, coma, spaces and - too. Tried also with that but it accepts too !"··%$&%((/=)**^¨`+

Code:

---

QRegExp rx7("[A-Z.- 0-9]{0,30}");

---

That's because an unescaped dot in a regular expression means "match anything".

Cheers,

Read about "special characters in regexp". It should looks like :

Code:

---

QRegExp rx7("[A-Z\\.\\- 0-9]{0,30}");

---

Double backslash derived from the principles of code C / C ++.

wow didn't know that about dot anda_skoa

Thanks Lesiok for the clear example :) You all helped me so much in a moment. :)
