GLUTMOUSEWHEELFUNC(3)

🎀 GLUTMOUSEWHEELFUNC(3) 🎀

okay so bestie, this page is from OpenGLUT - input, and it’s literally all about glutMouseWheelFunc 💖

✨ NAME ✨

glutMouseWheelFunc — sets the mouse wheel callback for the current window. no cap.

📚 LIBRARY 📚

OpenGLUT - input

🪄 SYNOPSIS 🪄

#include <openglut.h>

void
glutMouseWheelFunc(void( *callback )( int wheel, int direction, int x,
    int y ));

🎯 PARAMETERS 🎯

• callback — Client hook for mouse wheel events. it’s the lil function you hand over to catch those wheel moments 🫶

💫 DESCRIPTION 💫

If the mouse wheel is spun over your (sub)window, OpenGLUT will, in theory, report this via the MouseWheel callback. wheel is the wheel number, direction is +/- 1, and x and y are the mouse coordinates. periodt.

If you do not register a wheel callback, wheel events will be reported as mouse buttons.

This callback is bound to the current window. 💅

😭 CAVEATS 😭

Due to lack of information about the mouse, it is impossible to implement this correctly on X at this time. Use of this function limits the portability of your application. (This feature does work on X, just not reliably.) You are encouraged to use the standard, reliable mouse-button reporting, rather than wheel events.

bestie this is the part where we say: use the reliable mouse-button reporting, not the wheel-event chaos. it’s giving “portability who?” 💀

Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.
