Re: Support of Joystick/Gamepad in GTK+ 3.18

[Samik Ganguly <sganguly87 gmail com>]

Hello Jasper,
    Thanks for clearing that up. I was under the impression that SDL 
would interfere with mouse and keyboard handling of GTK+, but looks like 
one can initialize a specific SDL subsystem like SDL_INIT_JOYSTICK. Also 
as you said mouse and keyboard events are multiplexed, so GTK+ and SDL 
should both receive them but I just have to ignore them inside SDL. The 
challenge here, I think, is to initialize SDL inside a GTK+ widget. I'll 
get back if I can successfully do that, or encounter a problem doing it. 
I hope it'll still be relevant although it'll have some SDL topic in it.
Best regards,
Samik
