Date: Sun, 21 Sep 2003 19:52:42 -0600 From: Tyler Montbriand <tsm@accesscomm.ca> Subject: Re: [SDL] Hardware buttons on pocket pc I found it! :) It has to do with the UNICODE translation code, in SDL_dibevents.c, in the '#ifdef NO_GETKEYBOARDSTATE' block in DIB_HandleMessage(). The error handling is a little... aggressive. If it can't translate from unicode, it wipes out the virtual keycode.

13 This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&.
