lwjgl 3、如何获取当前线程中当前的OpenGL上下文？

我在 LWJGL 3 中使用 OpenGL 并收到以下错误；

Exception in thread "main" java.lang.IllegalStateException: There is no OpenGL context current in the current thread.
    at org.lwjgl.opengl.GL.getCapabilities(GL.java:157)
    at org.lwjgl.opengl.GL11.getInstance(GL11.java:1390)
    at org.lwjgl.opengl.GL11.glClearColor(GL11.java:1842)
    at com.base.engine.RenderUtil.initGraphics(RenderUtil.java:13)
    at com.base.engine.Main.<init>(Main.java:14)
    at com.base.engine.Main.main(Main.java:24)

这是 RenderUtil 类，其中从主类的构造函数调用 initGraphics。我还尝试在使用 GLFW 创建窗口后调用 initGraphics，这也生成了类似的错误消息。

    package com.base.engine;
    
    import static org.lwjgl.opengl.GL11.*;
    import static org.lwjgl.opengl.GL30.*;
    
    public class RenderUtil {
    
        public static void clearScreen() {
            glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
        }
    
        public static void initGraphics() {
            glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
    
            glFrontFace(GL_CW);
            glCullFace(GL_BACK);
            glEnable(GL_CULL_FACE);
            glEnable(GL_DEPTH_TEST);
    
            glEnable(GL_FRAMEBUFFER_SRGB);
        }
    }

另外，我没有使用多线程。要创建一个窗口，我调用该方法Window.createWindow(1366, 768, "Test");从我的主要方法。 ```` 私有静态长窗口；

    public static String createWindow(int width, int height, String title) {
        if (GLFW.glfwInit() == 0) {
            return "GLFW failed to initialise.";
        }

        GLFW.glfwWindowHint(GLFW.GLFW_SAMPLES, 4);
        window = GLFW.glfwCreateWindow(width, height, title,
                GLFW.glfwGetPrimaryMonitor(), 0);

        if (window == null) {
            GLFW.glfwTerminate();
            return "Failed to create window.";
        }

        GLFW.glfwMakeContextCurrent(window);
        return "GLFW has established a window.";
    }

I have tried putting `RenderUtil.initGraphics();` two different position in my main method, both resulting in errors.

        private boolean isRunning = false;
        private Game game;
    

        // This is the constructor
        public Main() {
            // Pos 1 - RenderUtil.initGraphics();
            isRunning = false;
            game = new Game();
        }

        public static void main(String[] args) {
            System.out.println(Window.createWindow(1366, 768, "Test"));
            // Pos 2 - RenderUtil.initGraphics();
            Main game = new Main();
            game.start();
        }

添加呼叫至GLContext.createFromCurrent()在结束时createWindow method.

需要此方法来设置 LWJGL GL** 类在底层使用的上下文。

EDIT:

自从最新的每晚（3.0.0b #11）以来，这不再有效，因为GLContext类不再存在。相反，添加GL.createCapabilities()在结束时createWindow method.
