Correct. The Glib dispatcher is not expected to work on a Mac or Windows. If you need that, please use GMainLoop yourself in a separate thread. > On the Gui side, I have the impression that it was dropped or got lost > during the major reworks for Qt 5.

The change you pointed to makes that true now also for non-GUI. That change is pointing towards future goals of making the CFRunLoop run on all threads: we've been having problems with certain Apple API (like Bluetooth) not working outside the GUI thread. > So I'm wondering if the glib event loop is supported for Qt5 on macOS, and > if so, how do I enable support for it? It's not. I don't think we'll accept patches for it either, so your options are to either patch Qt or to run drive the GMainLoop yourself. A third alternative is to change Glib so that it integrates with the CFRunLoop instead of driving things on its own. Then when Qt runs that (you have to set QT_EVENT_DISPATCHER_CORE_FOUNDATION to 1), Glib events get dispatched too. -- 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
