Examples of javax.media.opengl.GLAutoDrawable

javax.media.opengl.GLAutoDrawable
A higher-level abstraction than {@link GLDrawable} which suppliesan event based mechanism ( {@link GLEventListener}) for performing OpenGL rendering. A GLAutoDrawable automatically creates a primary rendering context which is associated with the GLAutoDrawable for the lifetime of the object. This context has the {@link GLContext#setSynchronized synchronized} property enabled so thatcalls to {@link GLContext#makeCurrent makeCurrent} will block ifthe context is current on another thread. This allows the internal GLContext for the GLAutoDrawable to be used both by the event based rendering mechanism as well by end users directly.
