It depends on the value of i, of course.

There was a question whether to use signed or unsigned as the size type, that somewhere turned into Qt's use of signed for string sizes/offsets being inconsistent with STL/CSL. I suppose it has wandered off a bit on a tangent, though. -- Matthew _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
