OpenGL context, or any context that is managed externally. This line is critical for LWJGL's interoperation with GLFW's GlfwSetKe圜allback(window, (window, key, scancode, action, mods) -> // the stack frame is popped automatically It will be called every time a key is pressed, repeated or released. Throw new RuntimeException("Failed to create the GLFW window") Window = glfwCreateWindow(300, 300, "Hello World!", NULL, NULL) GlfwWindowHint(GLFW_RESIZABLE, GLFW_TRUE) // the window will be resizable GlfwWindowHint(GLFW_VISIBLE, GLFW_FALSE) // the window will stay hidden after creation GlfwDefaultWindowHints() // optional, the current window hints are already the default Throw new IllegalStateException("Unable to initialize GLFW") Most GLFW functions will not work before doing this. GLFWErrorCallback.createPrint(System.err).set() will print the error message in System.err.
#GETTING STARTED JAVA LWJGL FREE#
Terminate GLFW and free the error callback Free the window callbacks and destroy the window ("Hello LWJGL " + Version.getVersion() + "!")

#GETTING STARTED JAVA LWJGL GENERATOR#
I started the project by selecting a new Gradle project in IDEA, and then I used the LWJGL Gradle generator to generate adle. I have set -XstartOnFirstThread in VM options. I'm following this LWJGL Getting started guide which is supposed to show a window, but I'm getting this error which suggests running on the main thread and initialising AWT or JavaFX prior.
