A good solution is found in: git@github.com:midjji/convenient_multithreaded_qt_gui.git

then it's just e.g.

run_in_gui_thread(new RunEventImpl([](){
        QMainWindow* window=new QMainWindow();
        window->show();
    }));

callable from any thread, at any time, while taking care of setting things up for you in the bg.

Note, this also takes care of creating a QApplication and executing it in a thread. But also works if you have already done so somewhere already.
