    Hi there,

    I am looking for an equivalent of the boost regexp:

    @
    "^[[:alpha:]][[:alnum:]_\-]*$"
    @

    with QRegExp.

    If I remember correctly, :alpha: is all alphabetic characters, not only latin1 characters.
    So [a-zA-Z] would be different to :alpha: :-(
    Any Ideas?

    Does anyone knows if the POSIX Unicode syntax works in Qt:

      Hi,

      AFAIK (I may be wrong though) not with QRegExp (I've tested it a long time ago and looked at QRegExp sources but didn't find anything).

      But if you can go with QRegularExpression then you should be good

        A damn, I knew there was something new in Qt5...
        Thanks for the hint.
        I will go with that one.
