Re: [pygame] Numeric wireless keyboard

[Brian Fisher <brian@xxxxxxxxxxxxxxxxxxx>]

I think you probably can't get those messages without creating a window, so try creating a window before getting events.

 Also, you don't want to have a separate poll and wait func, which are both called and both check for different messages. Both those functions remove messages from the queue, so if a your poll function gets a SDL_KEYDOWN message, it would end up throwing out the message and then your wait function would never receive it. Just do the Poll thing, and make it's switch statement do the prints for SDL_KEYDOWN as well.

Anyways, once your test program works for your normal keyboard, then you can try it out with the wireless in order to learn how SDL is or is not reading that things key data, which will help you understand where the problem lies and how to solve it.
