QApplication In Non-Main Thread

Question

I need to exec() a QApplication in a thread that is not main (my GUIs must be plugins that can be dynamically loaded and unloaded at runtime, so I have no access to the main

Answer 1

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

then its just e.g.

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

or whatever code you wish to run in the gui thread.

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