Qt5: Signals and QApplications inside Threads

Dear Genode folks,

I have built an application with Qt5. I want it to also be able to read
ROM modules from a report_rom server and to be able to handle updates to
that ROM using signals.

When I run QApplication::exec() however, it does not return and the
entrypoint cannot listen to signals, causing them to be ignored.

So I created another QThread and run my QApplication in there. Now I get
the following error:

    WARNING: QApplication was not created in the main() thread.

And the application does not do anything and does not react to events.

What can I do to be able to run both the qt event loop and the genode
event loop?




Met vriendelijke groet / kind regards,

Boris Mulder
