    Hi, All,

    I just wonder how I can use the Caretmode parameter of function "int QRegExp::indexIn ( const QString & str, int offset = 0, CaretMode caretMode = CaretAtZero ) const".

    First, if offset == 0, CaretAtZero, or CaretAtOffset has same meaning, and thus CaretAtZero is not useful.
    Second, if offset != 0, I should always use CaretAtOffset, since CaretAtZero has no meaning (since we don't match the string from offset 0.) Yet if I don't want to use CaretAtOffset, then I can just omit caret from the search pattern. This renders CaretAtOffset useless again.

    I just wonder, is there any actual useful case for the parameter 'CaretAtZero'?  Forgive me poor C++: I can not think of any useful case...   Could someone please point out some cases for me?  Thanks.
