d_radio_proc(3)

📦 version 4.4.3.1, in fedora 43, fedora 44

💖 d_radio_proc 💖

okay bestie, so this is a page straight out of the Allegro manual — like, the game programming library, you know the one 🎀 — and it's all about one lil' function called d_radio_proc. She's a dialog procedure that implements a radio button object. yes. the little circle-y ones. iconic behaviour. ✨

✨ SYNOPSIS ✨

#include <allegro.h>

int d_radio_proc(int msg, DIALOG *d, int c);

like. that's the whole signature. she's not complicated, she's just that girl. 💅

🌸 DESCRIPTION 🌸

so basically: a radio button object. that's her. that's the vibe. 🦋

A dialog can contain any number of radio button groups — no cap, as many as you want. And the way it works? Selecting a radio button causes the other buttons within the same group to be deselected. so only one can be the main character per group at a time, periodt. 👑

Here's the breakdown of the fields, and yes you need to know all of them:

  • The dp field points to the text string. that's the label, bestie, that's what everyone reads. 🎀
  • d1 specifies the group number. this is how the buttons know who their siblings are — same number, same group, same drama. 💜
  • d2 is the button style:
    • 0 = circle
    • 1 = square

circle for the classic look, square if you're feeling a little different. both valid. both slay. 🔥

no notes, no hidden behaviour, that's genuinely the whole thing. she's simple and she's perfect for it. 🌈
