I started the thread through some non-qt means(using pthread)..Before terminating the thread, would like to ensure eventloop is exited normally. But when qApp-quit() would take time before which thread is deleted. Is there any means that thread is deleted only after qt eventloop is exited normally? > -- > 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 >
