Bug 3224

Summary: SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH doesn't work after init

Description Anthony @ POW Games 2016-01-07 17:48:45 UTC 
SDL_androidtouch.c sets a callback in Android_InitTouch if SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH is set. The Wiki says that SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH can be used any time during runtime, but it only works if set before init. And will it cause problems if it's set after init, and Android_QuitTouch calls SDL_DelHintCallback when no callback was added?

No, it sets a callback that is called right away with the initial value of that hint, and then again any time the hint is changed.

Is this not working?

It appears to be working perfectly now (after I've slept and returned to the test code).

I'm trying to get more information about the right mouse button quit bug and was sure I had found a problem. Very sorry Ryan, forgive me.
Comment 3 Anthony @ POW Games 2016-01-08 19:36:10 UTC 
I just found the source of my confusion. I was calling:

SDL_SetHint("SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH", "1");

I didn't think it would matter - my lack of understanding how SetHint works.
