very clean and concise code! By the way, I ran the servere node index.js then run the qt app, it is just a blank page? Is there any missing configuration I should do?
Node and Qt are separate builds. You don't need to run the node server before running the Qt app. None of the builds should result in a blank page. The instructions on Github are the steps I followed to get the builds working on my system. It's quite possible that you need to tweak a thing or two on your system. You should try troubleshooting.
Kidding aside; nice job OP. Appreciate the hard work and xplatform is nice. Cheers
