(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_HINT_APP_ID

A variable setting the app ID string.

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

Remarks

This string is used by desktop compositors to identify and group windows together, as well as match applications with associated desktop settings and icons.

This will override SDL_PROP_APP_METADATA_IDENTIFIER_STRING, if set by the application.

This hint should be set before SDL is initialized.
