Application running in [Google Chrome Native Client](https://developers.google.com/native-client/).

See @ref platform for brief introduction. |

|
||||
@section WindowlessNaClApplication-usage Usage |
||||
|
||||
Place your code into exec(). The subclass must be then registered to NaCl API |
||||
using MAGNUM_WINDOWLESSNACLAPPLICATION_MAIN() macro. |
||||
@code |
||||
class MyApplication: public Magnum::Platform::WindowlessNaClApplication { |
||||
// implement required methods...
|
||||
}; |
||||

||||
@endcode |
||||
|
||||
If no other application header is included this class is also aliased to |
||||
`Platform::WindowlessApplication` and the macro is aliased to |
||||
`MAGNUM_WINDOWLESSAPPLICATION_MAIN()` to simplify porting. |
||||
|
||||
@section WindowlessNaClApplication-html HTML markup and NMF file |
||||
|
||||
You need to provide HTML markup containing `<embed>` pointing to `*.nmf` |
||||
file describing the application. |
||||
|
||||
@todoc Document this better, add "bootstrap" examples |
||||
|
||||
@subsection WindowlessNaClApplication-html-console Redirecting output to Chrome's JavaScript console |
||||
|
||||
The application redirects @ref Debug, @ref Warning and @ref Error output to |
||||
JavaScript console. See also @ref Corrade::Utility::NaClConsoleStreamBuffer for |
||||
more information. |
