Hi, I've seen the discussion this month about positioning windows.
The use-case is something concrete: the Devhelp [1] assistant window. For some background, Devhelp (and libdevhelp) is implemented flexibly: it can be used as a standalone app, it can be integrated into GTK IDEs, the standalone app can be called to search or open a symbol. And there is the Devhelp assistant window: it is typically used by a text editor, to ask Devhelp to show a small window with the documentation for the symbol under the cursor. And that is where positioning is necessary: to not occlude the line of text where the cursor is, and to show the documentation at a sensible place (near the cursor position). With Wayland, this should be implemented with a subsurface. I may be wrong, but in this case it's not possible, because it's not the same app (the same process). (For example you open a terminal, then open Vim, then you press a key and it opens the Devhelp assistant window). So, what would be your suggestion in such a use-case? To still retain the flexibility of Devhelp. Thanks, Sébastien [1] https://wiki.gnome.org/Apps/Devhelp (an API browser)
