class
WindowlessIosContextWindowless iOS context.
GL context using EAGL on iOS, used in WindowlessIosApplication. Does not have any default framebuffer.
Meant to be used when there is a need to manage (multiple) GL contexts manually. See Manually managing windowless contexts for more information. If no other application header is included, this class is also aliased to Platform::WindowlessGLContext
.

Function documentation
Magnum:: Platform:: WindowlessIosContext:: WindowlessIosContext(const Configuration& configuration,
GLContext* context = nullptr) explicit
Constructor.
Parameters | |
---|---|
configuration | Context configuration |
context | Optional Magnum context instance constructed using NoCreate to manage driver workarounds |
Once the context is created, make it current using makeCurrent() and create Platform::
Magnum:: Platform:: WindowlessIosContext:: WindowlessIosContext(NoCreateT) explicit
Construct without creating the context.
Move a instance with created context over to make it usable.
Magnum:: Platform:: WindowlessIosContext:: ~WindowlessIosContext()
Destructor.
Destroys the context, if any.
bool Magnum:: Platform:: WindowlessIosContext:: makeCurrent()
Make the context current.
Prints error message and returns false
on failure, otherwise returns true
. If the context is current on another thread, you have to release() it there first — an OpenGL context can't be current in multiple threads at the same time.
bool Magnum:: Platform:: WindowlessIosContext:: release() new in Git master
Release current context.
Releases a context previously made current using makeCurrent(). Prints error message and returns false
on failure, otherwise returns true
.
EAGLContext* Magnum:: Platform:: WindowlessIosContext:: glContext() new in Git master
Underlying OpenGL context.
Use in case you need to call EAGL functionality directly or in order to create a shared context. Returns nullptr
in case the context was not created yet.
