Running Qt apps on raspberry pi with window manager

[Bremenpl]

Hello there,
I have succesfully followed this great guide on how to crosscompile qt apps for raspberry pi and run them with own frame buffer:
https://wiki.qt.io/RaspberryPi2EGLFS

In the end however I have come to a conclusion that I need that window manager... But the apps only run in windowless form. Is it possible to somehow tell the app (by a flag/ parameter maybe) NOT to run with own framebuffer, but use the available window manager? I would really appreciate all help.

@SGaist Hi, thank you for answer. The application started to use the window manager after I called it with a parameter " -platform xcb"

Hi,

What window manager will you be using ? Xorg ? Wayland ? In both cases you need to build their respective platform plugin and tell your application at startup which one to use.

Ok so you are using Xorg.

If I understand correctly, its working as it should now ?
