I already know the answer to that question; it depends on the macro, and in some cases different versions have very different meanings. When the features evolve in ways that suggest there's a need for detection, the values of existing macros are bumped. That might not necessarily mean an incompatibility for users who just use the older version of the feature. _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
