DeferredDelete events not handled when created by GLib dispatched events

Details

    • Bug
    • Resolution: Done
    • P3: Somewhat important
    • 5.8.0 Alpha
    • 5.0.2
    • Core: Event loop
    • None

    Description

      Deferred delete events are not handled if they were posted from a glib event callback execution cycle.
      loop level for event = loop level for current thread.

      I believe the loop level should be incremented before calling g_main_context_iteration in QEventDispatcherGlib::processEvents.

      QScopedLoopLevelCounter loopLevelCounter(threadData);

      Test App supplied to reproduce the problem.
      unzip and ./run
