Notifies that a frame has ended. This
is a good time for applications to
collect statistics about the frame
since the Cogl.FrameInfo should hold
the most data at this point. No other
events should be expected after a
COGL_FRAME_EVENT_COMPLETE event.
Notifies that the system compositor has acknowledged a frame and is ready for a new frame to be created.
Identifiers that are passed to Cogl.FrameCallback functions (registered using
cogl_onscreen_add_frame_callback()) that mark the progression of a frame in some way which usually means that new information will have been accumulated in the frame's corresponding Cogl.FrameInfo object.The last event that will be sent for a frame will be a
COGL_FRAME_EVENT_COMPLETEevent and so these are a good opportunity to collect statistics about a frame since the Cogl.FrameInfo should hold the most data at this point.A frame may not be completed before the next frame can start so applications should avoid needing to collect all statistics for a particular frame before they can start a new frame.
