QStringList QString::split ( const QString sep,
SplitBehavior  behavior = KeepEmptyParts,
Qt::CaseSensitivity  cs = Qt::CaseSensitive 
) const

Splits the string into substrings wherever sep occurs, and returns the list of those strings. If sep does not match anywhere in the string, split() returns a single-element list containing this string.

If cs is true, the string is only split only where characters are found that match sep exactly. If cs is false, the string is split, the string is split where characters are found that match sep case insensitively (e.g. "and" matches "AND").

If behavior is QString::SkipEmptyParts, empty entries don't appear in the result. By default, empty entries are kept.


        QString str = "a,,b,c";
        QStringList list1 = str.split(",");
        // list1: [ "a", "", "b", "c" ]

        QStringList list2 = str.split(",", QString::SkipEmptyParts);
        // list2: [ "a", "b", "c" ]
