Class holding a valid drawing context.
1 void threadFunction() 2 { 3 Context context = new Context(); 4 // from now on, you have a valid context 5 * 6 // you can make OpenGL calls 7 glClear(GL_DEPTH_BUFFER_BIT); 8 } 9 // the context is automatically deactivated and destroyed by the 10 // Context destructor when the class is collected by the GC
If you need to make OpenGL calls without having an active window (like in a thread), you can use an instance of this class to get a valid context. * Having a valid context is necessary for every OpenGL call. * Note that a context is only active in its current thread, if you create a new thread it will have no valid context by default. * To use a $(U Context) instance, just construct it and let it live as long as you need a valid context. No explicit activation is needed, all it has to do is to exist. Its destructor will take care of deactivating and freeing all the attached resources. *
