Thanks Martin. I take it, your method would be a bit more efficient than polling? Or wouldn't it make much difference because the event loop keeps looping anyway? For example: Using the wakeup event, it will simply break out of the message handling a bit quicker. "if XPending(display) > 0" would have a "else" part where it fires the OnIdle event and then breaks out. Skipping (or making redundant) the "if needToWait ..." block of code. Either way, I like your idea.
