/**
|
||||
@brief Windowless CGL application |
||||
|
||||
Application for offscreen rendering using pure CGL. |
||||
|
||||
This application library is available on desktop OpenGL on OS X. It |
||||
is built if `WITH_WINDOWLESSCGLAPPLICATION` is enabled in CMake. |
||||
|
||||
## Bootstrap application |
||||
|
||||
Fully contained windowless application using @ref WindowlessCglApplication |
||||
along with CMake setup is available in `base-windowless` branch of |
||||
[Magnum Bootstrap](https://github.com/mosra/magnum-bootstrap)
|
||||
repository, download it as [tar.gz](https://github.com/mosra/magnum-bootstrap/archive/base-windowless.tar.gz)
|
||||
or [zip](https://github.com/mosra/magnum-bootstrap/archive/base-windowless.zip)
|
||||
file. After extracting the downloaded archive you can build and run the |
||||
application with these four commands: |
||||
|
||||
mkdir build && cd build |
||||
cmake .. |
||||
cmake --build . |
||||
./src/MyApplication # or ./src/Debug/MyApplication |
||||
|
||||
## General usage |
||||
|
||||
In CMake you need to request `%WindowlessCglApplication` component, add |
||||
`${MAGNUM_WINDOWLESSCGLAPPLICATION_INCLUDE_DIRS}` to include path and link to |
||||
`${MAGNUM_WINDOWLESSCGLAPPLICATION_LIBRARIES}`. If no other windowless |
||||
application is requested, you can also use generic |
||||
`${MAGNUM_WINDOWLESSAPPLICATION_INCLUDE_DIRS}` and |
||||
`${MAGNUM_WINDOWLESSAPPLICATION_LIBRARIES}` aliases to simplify porting. See |
||||
@ref building and @ref cmake for more information. |
||||
|
||||
Place your code into @ref exec(). The subclass can be then used directly in |
||||
`main()` -- see convenience macro @ref MAGNUM_WINDOWLESSCGLAPPLICATION_MAIN(). |
||||
See @ref platform for more information. |
||||
@code |
||||
class MyApplication: public Platform::WindowlessCglApplication { |
||||
// implement required methods...
|
||||
}; |
||||
MAGNUM_WINDOWLESSCGLAPPLICATION_MAIN(MyApplication) |
||||
@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. |
