Flags for SDL_MessageBoxButtonData.
Defined in SDL_messagebox.h, but apps should use #include <SDL3/SDL.h>
typedef enum SDL_MessageBoxButtonFlags
{0x00000001, /**< Marks the default button when return is hit */
SDL_MESSAGEBOX_BUTTON_RETURNKEY_DEFAULT = 0x00000002 /**< Marks the default button when escape is hit */
SDL_MESSAGEBOX_BUTTON_ESCAPEKEY_DEFAULT = } SDL_MessageBoxButtonFlags;
This enum is available since SDL 3.0.0.
