| 2166 | * events as 'Handled', then the OS will invoke its default behavior for |
||
| 2167 | * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to |
||
| 2168 | * terminate the app (and attempt to switch to the previous app, or to the |
||
| 2169 | * device's home screen). |
||
| 2170 | * |
||
| 2171 | * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL |
||
| 2172 | * to mark back-button-press events as Handled, if and when one is sent to |
||
| 2173 | * the app. |
||
| 2174 | * |
||
| 2175 | * Internally, Windows Phone sends back button events as parameters to |
||
| 2176 | * special back-button-press callback functions. Apps that need to respond |
||
| 2177 | * to back-button-press events are expected to register one or more |
||
| 2178 | * callback functions for such, shortly after being launched (during the |
||
| 2179 | * app's initialization phase). After the back button is pressed, the OS |
||
| 2180 | * will invoke these callbacks. If the app's callback(s) do not explicitly |
||
| 2181 | * mark the event as handled by the time they return, or if the app never |
||
| 2182 | * registers one of these callback, the OS will consider the event |
||
| 2183 | * un-handled, and it will apply its default back button behavior (terminate |
||
| 2184 | * the app). |
||
| 2185 | * |
||
| 2186 | * SDL registers its own back-button-press callback with the Windows Phone |
||
| 2187 | * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN |
||
| 2188 | * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which |
||
| 2189 | * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON. |
||
| 2190 | * If the hint's value is set to "1", the back button event's Handled |
||
| 2191 | * property will get set to 'true'. If the hint's value is set to something |
||
| 2192 | * else, or if it is unset, SDL will leave the event's Handled property |
||
| 2193 | * alone. (By default, the OS sets this property to 'false', to note.) |
||
| 2194 | * |
||
| 2195 | * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a |
||
| 2196 | * back button is pressed, or can set it in direct-response to a back button |
||
| 2197 | * being pressed. |
||
| 2198 | * |
||
| 2199 | * In order to get notified when a back button is pressed, SDL apps should |
||
| 2200 | * register a callback function with SDL_AddEventWatch(), and have it listen |
||
| 2201 | * for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK. |
||
| 2202 | * (Alternatively, SDL_KEYUP events can be listened-for. Listening for |
||
| 2203 | * either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON |
||
| 2204 | * set by such a callback, will be applied to the OS' current |
||
| 2205 | * back-button-press event. |
||
| 2206 | * |
||
| 2207 | * More details on back button behavior in Windows Phone apps can be found |
