03/27/2024, 6:29 PMOn linux you need a X11 display to create a X11 window.

03/27/2024, 6:32 PMAre you trying to interface with X11 directly? Because if you're just trying to make the main window or a second one, you can do that from platform agnostic code via compose.
Garret Yoder
03/27/2024, 6:32 PMIf you want to interface with X11 directly, JNI would be the route you'd likely want to go, but I'm not sure why you'd want to interface with X - especially since it's rapidly getting deprecated on most linux systems.

03/27/2024, 6:37 PMYeah you're going to want to use JNI for that. I imagine compose's implementation of that is internal. Everything it's going to expose to you on the surface is going to be something platform agnostic because it's JVM in the background.

03/27/2024, 6:38 PMOntop of that compose doesn't know what "x11" is, it's using Swing in the background for window management. I'm not even sure if Swing has X11-specific methods, it might. The point of the JVM was to avoid stuff like that usually. I'd go down the route of either a JNI interface, or see if you can do something via swing. You can access all the underlying Swing stuff from compose.

03/27/2024, 6:41 PMWell like compose provide a method to get the native window pointer, i was hopping to also get the display. But i think i will create the windows myself, this will be more easier.

Garret Yoder
03/27/2024, 6:43 PMOh I see. Yeah you could likely use JNI and xlib to do that.

03/27/2024, 6:47 PMI fact i already did it, I'm using Glfw. They is already a existing binding using JNA :
https://github.com/ygdrasil-io/wgpu4k/blob/feature/initial-version-with-basic-example/examples/glfw/src/main/kotlin/GlfwMain.kt
But using compose with it require a lot of boilerplate code and that not really documented, so, i was looking for a simpler solution.

03/27/2024, 6:50 PMI'd try to search around if there's an easy way to do it from Swing, because then you can apply the same method to compose
