Regex in Qt not matching string it should

So I have a function, lets call it getMatch. I wrote a regex to match a string that it receives but the Qt regex engine isn't matching it like I expect it to.

For demonstrations sake, here is some code:

bool getMatch()
{
    QString item = "BitwiseAND(Value, Mask)";
    QRegExp rx("\\w+\\([\\w+,\\s]+?\\)", Qt::CaseInsensitive);

    return rx.exactMatch(item);
}

This should return true every time, but it returns false.

I have tested the regex in online testers, and it should be fine.

I think what you want is this:

\\w+\\((\\w+(?:,\\s)?)+\\)

your regex is using [ instead of (, but that's a character class, whereas what you are doing is simply grouping and quantifying.
