C/C++ API to set screen for a window on Wayland

[Aleix Pol]

It depends on how you're placing your surface.

Given you're asking about a dock in the KWin list, you should be using
layer-shell. It does allow setting the output when placing it:
https://wayland.app/protocols/wlr-layer-shell-unstable-v1#zwlr_layer_shell_v1:request:get_layer_surface

As C++ API you can use layer-shell-qt:

Best of luck,
Aleix
