SDL_ShowSimpleMessageBox(3)

💖 NAME 💖

SDL_ShowSimpleMessageBox — pops up a cute lil modal message box, no fuss, no extra steps. bestie it's literally the easy mode of dialogs 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_messagebox.h>

bool SDL_ShowSimpleMessageBox(SDL_MessageBoxFlags flags, const char *title, const char *message, SDL_Window *window);

---

🎀 DESCRIPTION 🎀

Okay so — if your needs aren't complex (and let's be honest, sometimes they just aren't), this function is preferred over SDL_ShowMessageBox. like, it's the vibe when you don't need the whole menu of options, you just need a box on screen saying something. 💖

flags may be any of the following:

• SDL_MESSAGEBOX_ERROR — error dialog 😭
• SDL_MESSAGEBOX_WARNING — warning dialog ⚠️
• SDL_MESSAGEBOX_INFORMATION — informational dialog ✨

Not me about to explain the thread rules because they MATTER: this function should be called on the thread that created the parent window, or on the main thread if the messagebox has no parent. And heads up — it will block execution of that thread until the user clicks a button or closes the messagebox. it's giving "everything waits for you to tap that button," fr fr. 💀

But the good news?? This function may be called at any time, even before SDL_Init(). which makes it so useful for reporting errors like a failure to create a renderer or OpenGL context. iconic behavior honestly. 👑

On X11, SDL rolls its own dialog box with X11 primitives instead of a formal toolkit like GTK+ or Qt. no cap, it's handcrafted. 🧚

⚠️ Note that if SDL_Init() would fail because there isn't any available video target, this function is likely to fail for the same reasons. If this is a concern, check the return value from this function and fall back to writing to stderr if you can. please actually handle it bestie, don't just ignore it 🙈
