| blast007 | also replicated it in one of their test programs (testmouse.c) | 04:58 |
|---|---|---|
| blast007 | seems none of their tests use SDL_PollEvent(NULL) to check if there are any pending events | 04:58 |
| kj4 | hello all | 05:01 |
| blast007 | hi | 05:01 |

| blast007 | I also just tried always returning true from isEventPending and that had a major FPS hit. | 05:06 |
| blast007 | oh, I guess cuz we loop calling doEvent if events are pending, up to the max processing time, up to 100ms, so that explains my 9 FPS :) | 05:07 |
| blast007 | sent some messages to the wrong channel, so pretend these next three lines were from before my messages about replicating it in testmouse.c :) | 05:24 |
| blast007 | < blast007> if I replace SDL_PollEvent with SDL_WaitEventTimeout and pass 1 for the timeout (for 1 millisecond) it works again | 05:24 |
| blast007 | < blast007> more specifically, it seems I only need to replace the SDL_PollEvent(NULL) in SDLDisplay::isEventPending (in SDL2Display.cxx) with SDL_WaitEventTimeout(NULL, 1) | 05:24 |
| blast007 | < blast007> when I wrap event processing with 'if (SDL_PollEvent(NULL) == 1)' in another test program I have it too no longer accepts input and throws up a not responding message | 05:24 |

| tupone | good | 12:53 |
| tupone | maybe there is a bug in SDL, as it says it is automatically called | 12:54 |
| blast007 | I had someone in SDL tell me that SDL_PollEvent(NULL) was "never meant for checking for pending events", but that seems to contradict the documentation | 12:55 |
| blast007 | in #SDL* | 12:55 |
| blast007 | maybe I'll get some better responses when other people wake up | 12:56 |
| tupone | :) | 12:56 |
| blast007 | I intend to submit it as an issue on SDL's github repo today | 12:56 |
