Hide Window on Start-Up

[dabfalcon]

Keep up the good work on ckb! My problem is that the ckb window appears every startup, which I then have to exit. I am running Manjaro KDE. I thought I was smart and make a startup script launching 'ckb --background' to only start the background process. This worked for the first reboot but not subsequent ones.

How can I autostart ckb but not have it seen?

There's currently a bug where the session restore causes the window to pop up. You can fix it by going to System Settings > Startup and Shutdown > Desktop Session and adding ckb to "Applications to be excluded"

Thanks ccMSC. Legend.

Regarding session restore bug, it is because QGuiApplication is modifying arguments provided to the Application - when creating QGuiApplication instance -session param is removed. I think the proper way to check if App is being run during session restore is to use QGuiApplication::isSessionRestored().

See following patch, works for me on Linux + KDE - ckb restored by KDE with -session xyz param is hidden on start.

@diijkstra bah, didn't know that. Could you send me a pull request for that change, please?
