When pressed, + * the OS will emit back-button-press events, which apps are expected to + * handle in an appropriate manner. If apps do not explicitly mark these + * events as 'Handled', then the OS will invoke its default behavior for + * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to + * terminate the app (and attempt to switch to the previous app, or to the + * device's home screen). + * + * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL + * to mark back-button-press events as Handled, if and when one is sent to + * the app. + * + * Internally, Windows Phone sends back button events as parameters to + * special back-button-press callback functions. Apps that need to respond + * to back-button-press events are expected to register one or more + * callback functions for such, shortly after being launched (during the + * app's initialization phase). After the back button is pressed, the OS + * will invoke these callbacks. If the app's callback(s) do not explicitly + * mark the event as handled by the time they return, or if the app never + * registers one of these callback, the OS will consider the event + * un-handled, and it will apply its default back button behavior (terminate + * the app). + * + * SDL registers its own back-button-press callback with the Windows Phone + * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN + * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which + * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON. + * If the hint's value is set to "1", the back button event's Handled + * property will get set to 'true'. If the hint's value is set to something + * else, or if it is unset, SDL will leave the event's Handled property + * alone. (By default, the OS sets this property to 'false', to note.) + * + * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a + * back button is pressed, or can set it in direct-response to a back button + * being pressed. + * + * In order to get notified when a back button is pressed, SDL apps should + * register a callback function with SDL_AddEventWatch(), and have it listen + * for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK. + * (Alternatively, SDL_KEYUP events can be listened-for. Listening for + * either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON + * set by such a callback, will be applied to the OS' current + * back-button-press event. + * + * More details on back button behavior in Windows Phone apps can be found + * at the following page, on Microsoft's developer site: + * http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx + */ +#define SDL_HINT_WINRT_HANDLE_BACK_BUTTON "SDL_WINRT_HANDLE_BACK_BUTTON" + +/** \brief Label text for a WinRT app's privacy policy link + * + * Network-enabled WinRT apps must include a privacy policy.
