Solution 1:[1]

QRegExp case insensitive search mode is enabled with Qt::CaseInsensitive.

When you use QRegularExpression that is based on PCRE regex engine, you may use QRegularExpression::CaseInsensitiveOption:

The pattern should match against the subject string in a case insensitive way. This option corresponds to the /i modifier in Perl regular expressions.

Solution 2:[2]

In python, it's:

re = QRegularExpression(pattern, QRegularExpression.CaseInsensitiveOption | QRegularExpression.DotMatchesEverythingOption)

And if you need 2 options

re = QRegularExpression(pattern, QRegularExpression.CaseInsensitiveOption | QRegularExpression.DotMatchesEverythingOption)
