Converting search string to QRegularExpression pattern

I have a widget that has API to set a
QRegularExpressionthat will be used to highlight certain contents of the widget. The user is able to enter a regular expression in aQLineEditand everything works quite well. I'd now like to give the user the ability to toggle between "regex mode" and "plain string compare" mode as some users might not know regex and others are annoyed to escape all the characters if they are looking for something with special symbols.My question: Is there any way I can convert the "plain string" to a valid
QRegularExpression? I'd like to avoid modifying said widget to offer search & highlight capabilities by just doing good oldQString::compare(). I looked through the docs but it seems thatQRegularExpressiondoesn't offer such a feature and it's not enough that I just escape any non-alphanumeric character.I'd be thankful for any kind of help & advice.
