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

SDL_HINT_ANDROID_TRAP_BACK_BUTTON

A variable to control whether we trap the Android back button to handle it manually.

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_ANDROID_TRAP_BACK_BUTTON "SDL_ANDROID_TRAP_BACK_BUTTON"

Remarks

This is necessary for the right mouse button to work on some Android devices, or to be able to trap the back button for use in your code reliably. If this hint is true, the back button will show up as an SDL_EVENT_KEY_DOWN / SDL_EVENT_KEY_UP pair with a keycode of SDL_SCANCODE_AC_BACK.

The variable can be set to the following values:

• "0": Back button will be handled as usual for system. (default)
• "1": Back button will be trapped, allowing you to handle the key press manually. (This will also let right mouse click work on systems where the right mouse button functions as back.)

This hint can be set anytime.

Version

This hint is available since SDL 3.1.3.
