This has come up a couple times for me through the years (essentially make a network request and don’t return until the request has finished).
Is there an example anywhere of the "Thiago" (proper.. 😊 ) way to code this? I see this issue in a similar vane to using QThread, when the Trolls/Nokia/TQP (I forget who originally wrote it) wrote up a small but very effective white paper on the proper method of using Qthread, it clarified a ton of questions for many people.

Please do as I said: insert a return and let the event loop handle calling your slots. Nested event loops are an anti-pattern. Don't write code like that unless you really must. And if you do, use QEventLoop. Don't use processEvents(). That's only slightly less evil than sleep(). -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel DPG Cloud Engineering _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
