Min Max Regex for QtCore.QRegExp

What would be a proper syntax to write a regex expression that limits a user from entering only integer numbers between a range of: 15 and 764 Thanks in advance!

Solution

  • Use following regular expression

    ^(1[5-9]|[2-9]\d|[1-6]\d\d|7[0-5]\d|76[0-4])$
    • 1[5-9]: 15 ~ 19
    • [2-9]\d: 20 ~ 99
    • [1-6]\d\d: 100 ~ 699
    • 7[0-5]\d: 700 ~ 759
    • 76[0-4]: 760 ~ 764

    Escape \ if you use the pattern inside string literal.

    "^(1[5-9]|[2-9]\\d|[1-6]\\d\\d|7[0-5]\\d|76[0-4])$"
