This is probably a superstitious/religious belief, I do not like polling due to the latency/overhead tradeoff that you have to make anyway. Here I need fairly low latency (about 50ms) so the polling should be at that interval at most.
Also, I would bet that QSocketNotifier does not work with stdin, but I may be wrong. Why do you want to avoid polling? It's quite natural thing when working > with asynchronous data sources. > E.g. you can use QSocketNotifier to let QEventLoop do polling for you. > >
