void GraphicsEngine::WindowRenderer::do_close (  GraphicsEngine *  engine  )

Closes all the windows on the _window list. Definition at line 1265 of file graphicsEngine.cxx.

void GraphicsEngine::WindowRenderer::do_flip (  GraphicsEngine *  engine  )

Flips the windows as appropriate for the current thread. Definition at line 1230 of file graphicsEngine.cxx.

void GraphicsEngine::WindowRenderer::do_frame (  GraphicsEngine *  engine  )

Executes one stage of the pipeline for the current thread: calls cull on all windows that are on the cull list for this thread, draw on all the windows on the draw list, etc. Definition at line 1192 of file graphicsEngine.cxx.

void GraphicsEngine::WindowRenderer::do_pending (  GraphicsEngine *  engine  )

Actually closes any windows that were recently removed from the WindowRenderer. Definition at line 1305 of file graphicsEngine.cxx. Referenced by GraphicsEngine::setup_scene().
