C++ (Cpp) RenderStopped Examples

Example #1

File: vfesession.cpp Project: fourks/povray

void vfeSession::StateChanged (pov_frontend::State NewState)
{
  if (NewState == kReady || NewState == kStopping)
    if (m_BackendState > kReady)
      RenderStopped () ;
  if (NewState == kRendering)
    m_StartTime = GetTimestamp();
  m_BackendState = NewState ;
  NotifyEvent(stBackendStateChanged);
}
