Backends: Add Xlib backend #7262
Conversation
|
Hello, I've been a little hesitant because #3372 tackle more and is generally more overwhelming (vulkan + multi-viewports). From my POV not being a user of X11 if I merge either I would reliant on other people to provide support. So I may need to ask for a bit ofc commitment from either of you to merge this. I think it may be sane to merge a simpler version first (more similar to yours) but it would be also sane to review the same-feature pars of #3372 and pick best from both world, if there's something to pick. Depending on the situation and people's interested in maintaining/improving this, I might decide that it would be preferable to host it on its own repo, or merge into main repo. Thanks! |

There was a problem hiding this comment.
Your setup breaks the classic ButtonPress/ButtonRelease events im guessing because you handle them with XInput extension? Would be nice maybe to document that you need to use GenericEvent in the client application or use the classic ButtonPress/ButtonRelease in the backend to avoid blocking them
But im not sure exactly if thats the cause of the classic events not firing, couldn't find anything about it in the docs
Add Linux Xlib backend for handling events (mouse, mouse cursor, keyboard, clipboard), and offer one example with Xlib+OpenGL3 (using GLX). I didn't look at multi viewports, it should be possible to implement it, and I could do that if requested :)
I wrote this for my libtas project where I hooked code into Linux games, most of which don't use SDL. I thought some other people might be interested.
