glx_opengl2_example? #1194
Comments
There's none, it would be nice if you want to contribute one? (closely modelled after the existing example) |
Closing this as it won't happen by itself. If someone is interested in creating such example they can PR it. Being a variant of initializing an OpenGL context it should be easy to recreate one if you follow X11+GL tutorials. |
You can copy my X11 code (gpulib_imgui.h file), although it's for modern GL and C bindings of dear imgui: https://procedural.itch.io/lib0-engine The hardest part was clipboard pasting, if you paste more than 262145 bytes of characters in X11 you have to do that asynchronously in chunks. I couldn't care less so I just wait |
[OT: just because the issue is closed] As far as I know, on Ubuntu Linux (one of the most popular Linux distribution), X11 will be replaced at some point by another library called Wayland (see: https://wayland.freedesktop.org/). However it seems that Xorg will still be the default library in April, long term support, version (18.04 LTS) (see: https://insights.ubuntu.com/2018/01/26/bionic-beaver-18-04-lts-to-use-xorg-by-default/). The Wayland version should have a sort of backward-compatibility layer to run X programs in any case. So I think it makes sense to keep supporting X11 on Linux (even if I prefer using higher level libraries like glfw, glut or SDL2 to cross the gap). Sorry for the O.T. post. |
It suck so hard perf wise I can't believe people are serious about wayland at all. |
😄 I've never tried Wayland myself. X11 works well enough for me. |
I also want to note wayland has been 9 years in development and even its native apps still have visual glitches and jerkiness. Just give them another 9 years to sort it out. |
I am interested in the extra example if they are proven to be useful, but they'd need to be done to match the existing examples so I can keep them in sync. I'm curious however how many of our target audience would really bother using X or Wayland without a wrapper (glfw/glut/SDL as you pointed @Flix01) and actually need an example? By the way I expect in the upcoming month or so to refactor the examples/ folder and somehow find a way to separate the renderer (OpenGL3, DirectX11) from the platform (e.g. GLFW, Win32), that is to share more code. This is motivated by the fact that work on multiple viewport #1542 will put more burden on the platform layer. The difficulty will be to refactor that without losing some of the imgui examples simplicity. |
To me the point is simple: X (or Wayland) is for Linux just what the plain Windows API is for Windows. I personally prefer using wrappers also because I can write code that is more portable, but the answer to your precise question is probably: people that use Linux and don't want to link to any wrapper library (the same happens for Windows users that want a plain Window API binding).
Yes, this is the way to go if you need to add some other platform properties/services.... |
So is there going to be a GLX w/ OpenGL3+ back-end after all? "Wastland" is still a few years from been ready and mainstream. If no one, I will do it and include it as my "default" binding for MaXX Desktop. cool? |
Simple and functional extension, as nuklear do.
