Qt 5.14.2 QWindow context for linux, what windowing system does Qt use?

[scott_craig]

Does Qt use xlib or xcb for OS window handles? What does type winID() return on Linux?

Hi,

It will depend on your distribution. Either xcb or wayland. But currently it's more likely to be xcb.

Thanks is the winID() always a pointer type?

[SGaist]

AFAIK, no. It's an identifier that is platform dependent.
