Yes, it get triggered from the virtual call `WindowDelegateProcessEvent()`.

If a process event with `eBroadcastBitSTDOUT` or `eBroadcastBitSTDERR` is detected, it calls `m_window_sp->HandleProcessEvent(event_sp)`. `Window::HandleProcessEvent(const lldb::EventSP &event_sp)` method propagates the event to its delegate: `m_delegate_sp->WindowDelegateProcessEvent(event_sp)`. `ConsoleOutputWindowDelegate::PollProcessOutput()` function then fetches the actual output data using `process->GetSTDOUT` and `process->GetSTDERR` and appends it to the console buffer via `AppendOutput()`
