GLUTKEYBOARDFUNC(3)

💖 GLUTKEYBOARDFUNC(3) 💖

okay bestie, welcome to the OpenGLUT input corner of the manual — this one is literally the page that tells you how to make your window actually hear you when you smash a key. it's giving main character energy for real. and yes, the manual name is GLUTKEYBOARDFUNC and it lives in the OpenGLUT - input library, so you already know what time it is. 🎀

---

✨ LIBRARY ✨

OpenGLUT - input — that's the vibe check, bestie. input handling, no cap. 💅

---

🦋 SYNOPSIS 🦋

#include <openglut.h>

void
glutKeyboardFunc(void( * callback )( unsigned char key, int x, int y ));

---

🌸 PARAMETERS 🌸

• callback — your lil client function, the one that's gonna get called whenever a keyboard event happens. you write it, OpenGLUT runs it. that's the deal. 🫶

---

✨ DESCRIPTION ✨

okay so here's the tea: this callback registration is how you handle traditional ASCII keyboard input. the general rule of thumb (and it's a good one) is that if a key has a common ASCII code, then OpenGLUT assigns that code to the key and calls the Keyboard callback with the ASCII code in the key parameter. easy peasy. 🌈

for other keys though? nope, you gotta use glutSpecialFunc(). and lowkey, not all keys can be reported by OpenGLUT at all. that's just the way it is, bestie. 💀

as a convenience (and it IS convenient, obsessed), the mouse coordinates — relative to your window — are also returned. so you get the key and the mouse position, together. iconic. 🐭✨

and the big one: this callback is bound to the current window. periodt. 💅

---

😭 CAVEATS 😭

this function is not very international-friendly. like, it's not multilingual. it's monolingual and it's fine with that. 🙈

windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent. always. no exceptions. so if your events are showing up somewhere you didn't expect, that's why, bestie. 💀
