That's no problem even with 4.8. 32-bit Cocoa apps (both PPC and Intel) targeting 10.5 and above with Qt 4.8.1 work just fine. And I suppose 4.8 will stick around for a long time so no worries quite yet. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
