Use of QValidator in QLineEdit

[giorgik]

Hello everyone, I have a question about the use of QValidator in QLineEdit:

QRegExp rx("^[1-9]{1, 3}$");
QLineEdit *lineedit = new QLineEdit(this);
lineedit->setValidator(new QRegExpValidator(rx, lineedit));

QRegExp rx("^[1-9]{1, 3}$");
QLineEdit *lineedit = new QLineEdit(this);
lineedit->setValidator(new QRegExpValidator(rx, lineedit));

To copy to clipboard, switch view to plain text mode 

The widget will not let me enter any numbers, why?
I expected at least to enter a number between 1 and 999, but nothing.
What's missing?

use QIntValidator

Yes mentalmushroom, works with QIntValidator but I wanted to use QRegExpValidator...

What if you use {0,3} and not {1,3}? Also skip "^" and "$", they are not required here.

I then found out where wrong:

{1, 3}

{1, 3}

To copy to clipboard, switch view to plain text mode 

I put a space after the character ','. the correct form is

{1,3}

{1,3}

To copy to clipboard, switch view to plain text mode

keep in mind this won't let you enter numbers that contain zeros, e.g. 109.
