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".
