00:09 <DemiMarie> kelnos: what about patching GTK to expose the hooks you need?

00:11 <DemiMarie> Is Weston a thing outside of embedded?

00:12 <kelnos> i've thought about that, but i'm concerned the gtk maintainers wouldn't go for it (it would tie them to xdg-surface as the shell they use, etc.). gtk3 is also seemingly in maintenance-only mode, another hurdle. but i suppose it wouldn't hurt to ask. i'm currently targeting whatever gtk version will be stable in a year and a half or so, so now is probably a good time to get something like that in

00:15 <DemiMarie> kelnos: port to gtk4?

00:16 <kelnos> not feasible. xfce just made it to gtk3 not too long ago. gtk4 port would take many years. and gtk4 removes some things that we need (like GtkPlug/GtkSocket for X11, and gdk_window_foreign_new())

00:16 <kelnos> (and frankly we just don't like the direction gtk4 has gone in)

00:17 <DemiMarie> in that case you are probably better off with a new toolkit

00:35 <kelnos> yup, but that is a problem for another year

08:05 <pq> kelnos, I am confused by you fighting with gtk but also saying that your nested compositor is not using gtk. A nested compositor that mostly just forwards things through may be best written without any client-side toolkit towards its parent compositor, since client-side toolkits generally do not consider that use case and their desire to abstract away Wayland details is actively harmful in achieving that.

08:59 <kelnos> pq: the nested compositor library does not itself use gtk, but the goal is to allow an app that is written using gtk to embed the compositor in it

09:00 <pq> oh, ouch

09:00 <kelnos> "ouch" does sum it up quite well

09:02 <kelnos> at any rate, i did temporarily solve my problem... by reading gtk's internal implementation headers so i could steal the xdg_surface/xdg_toplevel pointers from GdkWindowImplWayland instances. not a long-term solution (though this sort of approach does work for libgtk-layer-shell), but good enough for now so i can continue to make progress
