In wxwidgets, how do I lock a vector that is shared between gui thread and worker thread?

Question

If I can't call lock on a mutex in the main application thread (my event handler because you can't lock the main gui thread), how do I share any information between my worker and my main thread?

Answer 1

Just have your worker thread communicate with the main thread through the event handling system. Use AddPendingEvent to send status messages back to the main thread and ProcessEvent to handle the updates.
