GLUTBUTTONBOXFUNC(3)

💖 NAME 💖

okay so this page is all about glutButtonBoxFunc — it sets a button-box button callback. And the manual name is GLUTBUTTONBOXFUNC(3), so you know exactly what you opened, bestie. 💅

---

📚 LIBRARY 📚

OpenGLUT - input. That's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

Here's the exact spell, no cap:

#include <openglut.h>

void
glutButtonBoxFunc(void( *callback )( int button, int state ));

---

🫶 PARAMETERS 🫶

• callback — Client buttonbox button hook. 🫶

---

✨ DESCRIPTION ✨

A dials-and-buttons box has buttons numbered from 1 to this value, inclusive:

glutDeviceGet(
       GLUT_NUM_BUTTON_BOX_BUTTONS)

The callback parameters are the button and its state, and that state is either GLUT_UP or GLUT_DOWN. 🎀

The callback is bound to the current window. 👑

---

⚠️ CAVEATS ⚠️

OpenGLUT does not implement button-box support. periodt.

Also, in contrast, mouse buttons are numbered from 0 in the GLUT API. This is a wrinkle. 😭
