processEvents() does not guarantee it will be fully painted either. The dialog may be covered by another window and made visible only after you started your heavy treatment. You'd have to periodically call processEvents() to ensure it gets repainted when necessary. But it does look like this a regression. The plan is to rapidly release 5.3.1 with the pending fixes from the last two months, plus maybe this fix. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
