SDL_APP_WILLENTERBACKGROUND is now sent as soon as the app is told that it is about to go to the background. SDL_APP_DIDENTERBACKGROUND is sent via a WinRT 'deferral operation', which is how WinRT gives apps a bit of extra time (multiple seconds worth) to prepare for an app-backgrounding. The distinction may be important as the deferral operation's code is always run in a separate thread. For Direct3D-only apps, this means that between the two SDL app-backgrounded events, SDL_APP_WILLENTERBACKGROUND will be the only one run from the main thread. Given that some WinRT operations can only be done on the main thread (operations to the CoreWindow fall into this category), this could be important. It is important to note that pre-deferral code may only have a very short bit of time to execute code, less so than code run in the deferral operation (where SDL_APP_DIDENTERBACKGROUND is sent from), which usually gets several seconds to run. |

Simple DirectMedia Layer (SDL) Version 2.0 --- http://www.libsdl.org/ Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games. SDL officially supports Windows, Mac OS X, Linux, iOS, and Android. Support for other platforms may be found in the source code. SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python. This library is distributed under the zlib license, which can be found in the file "COPYING.txt". The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date. More documentation and FAQs are available online at: http://wiki.libsdl.org/ If you need help with the library, or just want to discuss SDL related issues, you can join the developers mailing list: http://www.libsdl.org/mailing-list.php If you want to report bugs or contribute patches, please submit them to bugzilla: http://bugzilla.libsdl.org/ Enjoy!
