Kind of true... but override-redirect windows will bypass that positioning control the WM has... it's common to abuse these for all sorts of fun and games. > If Wine could really benefit from some optional hand-holding, I think > it would be okay to have a Windows-specific interface to help fill the > gaps.

I also would want to avoid baking explicit absolute positioning into wayland protocol - be it as a core agreed to add-on to xdg-shell or even a "commonly supported extension". What I'd like it some better solution. For example - if an app wants to absolute position a window because it's doing a custom "my own notification popup" much like Chrome and Firefox now like to do in X11, then I'd prefer this be explicitly exposed as a "notification surface with requested screen location hints" and so the compositor can decide to do something more intelligent with it. I am sure this list of use cases will probably be extensive and also depend on the API in wine that is being wrapped and intercepted - the higher level it is, the more it knows about the intended use case. > Even better if that's not necessary. > > > Thanks, > pq -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
