Implement a regex in QRegExp

[Alir3z4]

Here is the regex and how i use it.

QString regexPattern =
            "^(?:http|ftp)s?://"    // http:// or https://
            "(?:(?:[A-Z0-9](?:[A-Z0-9-]{0,61}[A-Z0-9])?\\.)+(?:[A-Z]{2,6}\\.?|[A-Z0-9-]{2,}\\.?)|"    // #domain...
            "localhost|"    // localhost...
            "\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3})"    // ...or ip
            "(?::\\d+)?"    // optional port
            "(?:/?|[/?]\\S+)$";
    _regexValidator = new QRegExpValidator(QRegExp(regexPattern), this->parent());

QString regexPattern =
            "^(?:http|ftp)s?://"    // http:// or https://
            "(?:(?:[A-Z0-9](?:[A-Z0-9-]{0,61}[A-Z0-9])?\\.)+(?:[A-Z]{2,6}\\.?|[A-Z0-9-]{2,}\\.?)|"    // #domain...
            "localhost|"    // localhost...
            "\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3})"    // ...or ip
            "(?::\\d+)?"    // optional port
            "(?:/?|[/?]\\S+)$";
    _regexValidator = new QRegExpValidator(QRegExp(regexPattern), this->parent());

To copy to clipboard, switch view to plain text mode 

Problem is that the QRegExpValidator::validate() never returns Acceptable.
I don't know what part i missing in it.
Also the regex is for URL validation ;)

For the record, the regular experssion itself is stolen from django.core.validators.URLValidator

For a start your regular expression is broken and your compiler is probably warning you about an unknown escape "\.". You need to double-up the \\ before the periods in the domain name and ip address.

Once you have that fixed, your domain name would have to be all upper-case.

Actually no, the compiler didn't warn me about unknown escape, beside that i did try also double slash \\. but no didn't work.
As you said i tried to make domain In upper-case, but the results was same !
And something else can somehow make that regex case-insensitive by the QRexExp itself?

Update:
Yes you were right, i just:

_regexValidator = new QRegExpValidator(QRegExp(regexPattern, Qt::CaseInsensitive), this->parent());

_regexValidator = new QRegExpValidator(QRegExp(regexPattern, Qt::CaseInsensitive), this->parent());

To copy to clipboard, switch view to plain text mode 

and make it CaseInsensitive , and now it works. i should test it more.
Thanks ChrisW67
