    QRegExp regExp (regExpStr, Qt :: CaseInsensitive, QRegExp :: RegExp2);
    sortModel-> setFilterRegExp (regExp);

    Is used.

    I want to create a regExp that contains A in regExpStr but not B.

    So I did A | [^ (B)] but it does not respond. What should I do?

      • use QRegularExpression instread of QRegExp
      • https://www.regular-expressions.info/lookaround.html

      If the above is not enough use 2 separate proxys one for the A part and this one for the not B part

        @Pada_ said in Sort Model regExp Error.:

        [^ (B)]

        That means: not one of the characters: space, (, B, ). Probably nothing like what you want. And the | for "or" does not correspond to "contains A in regExpStr but not B." Might be simpler to follow @VRonin's suggestion of two separate proxies.

          I do not know what it means to use two proxies.

            Your current program:
            source model -> QSortFilterProxyModel with "A | [^ (B)]" as filter ->view

            what we are suggesting:
            source model -> QSortFilterProxyModel with "A" as filter -> NegativeSortFilterProxyModel with "B" as a filter ->view
