This might sound like a dumb question...

What should a wxThread be used for?

It depends on the CPU time consumption of every thread and the required wake-ups per second.

There are several situations. An application can contain a several inherited from wxThread classes and uses the only instance of the every inherited class. For example, a programm contains a CReaderThread class to read a big amount of data from a file and in parallel displays progress information in a status bar. After the reading process the application handles the data in some way using an instance of the wxThread inherited class (for example CDataHandleThread) to give someone ability to see the handling progress and stop this process.

From other hand, if the data handling task is easy to split on parallel subtasks, then the application creates several instaces of a CDataHandleWorkerThread class to handle the data and one thread to manange all the worker threads. Very often the number of the worker threads equal to a processors number of a computer.

The text above contains simple examples how to use the wxThread class, there are a number of other more complex examples.

Funny poll ... if a person selects NONE his background on GUI programming is most likely questionable. There is always one thread in your app, wether you like it or not ;-)

Interesting poll though. I worked with threads a lot (and still do) but not in my wxWidgets apps. There was no need for it, I can imagine when creating an internet app of some kind, it would be the way to go to put a connection in a thread (at least at the server side)..

Well, the main wxThread is NULL, so I think it would be technically correct on windows 8)

In one of my applicatoins I use 20-30 threads to crawl over the network. Each thread performs some function with a host. Parallel execution in this fashion is orders of magnitude quicker then processing without multithreading.
