Date: Tue, 14 Dec 2004 12:08:30 +0100 From: Marcin Konicki Subject: Re: [SDL] SDL 1.2.8 Prerelease I'm sending small fix for BeOS, which prevents filling up SDL's message queue too fast. Without it, SDL receives "key down" messages from BeOS code, for each key repeat (BeOS handles key repeats itself, and application can check if received "key down" message from BeOS is first time key down, or if it's repeat, and which repeat it is). Since there is no way for "sdl driver" to turn off "default" SDL's key-repeat mechanism, they were working both at the same time (and queue could be filled up very fast). So this patch removes handling "key down" message from BeOS if it's key_repeat "type".
