annotate docs/man3/SDL_KeyboardEvent.3 @ 4170:092c0bc69155 SDL-1.2

Fixed bug #618 Description From Tim Angus 2008-08-30 12:23:56 (-) [reply] As we all know SDL 1.2 doesn't handle dead keys well since one key press potentially equals two (or more) characters. For example, on many layouts, keying <backquote>,<space> results in <no character>,<backquote><space>. Since the unicode member of the SDL_keysym struct only has room for one character, only one can be returned. On Linux, the first character is returned. On Windows however, unless the exact number of characters generated by the keypress is 1, nothing is returned. The following patch addresses this inconsistency. Updated patch which includes a further fix to the handling of the numpad when numlock is on. This further fix is courtesy Amanieu d'Antras.

28 The \fBtype\fR and \fBstate\fR actually report the same information, they just use different values to do it! A keyboard event occurs when a key is released (\fBtype\fR=\fBSDK_KEYUP\fP or \fBstate\fR=\fBSDL_RELEASED\fP) and when a key is pressed (\fBtype\fR=\fBSDL_KEYDOWN\fP or \fBstate\fR=\fBSDL_PRESSED\fP)\&. The information on what key was pressed or released is in the \fI\fBkeysym\fR\fR structure\&.
