2. OpenGL: In OpenGL, the getCode method can be used to determine which key was pressed in a callback function. For instance, the code below demonstrates how to handle the key press event for the Esc key:c++
3. GLFW: Similarly to OpenGL, the getCode method in GLFW can be used to determine the key code associated with a particular key event. The code below demonstrates how to use the getCode method to detect a key press event:c++ void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) { if (action == GLFW_PRESS) { std::cout << "The " << key << " key code was pressed\n"; } } ``` In conclusion, the KeyEvent getCode is a versatile method used in various C++ libraries to obtain the unique code associated with a particular key event. Depending on the library, the method is used differently, but it ultimately serves the same purpose.
