[wxPython-users] pubsub from threads

[Jorgen Bodde]

You cannot use pubsub because you will call your main gui in the
thread context of your worker thread. Which is basically the same as
just calling GUI elements from inside your thread. I would suggest
using a thread safe QUEUE where you post data in, and use OnIdle or
any other mechanism to read messages back inside the GUI thread. Also
postevent will work, but then you will use GUI related stuff in a
working thread and it's not really decoupled.
