Fixed bug #750
Since many different event structures include windowID it should be placed near
the beginning of the structure (preferably right after type) so it's position
is the same between different events.
This is to avoid code like this:
if (event.type == SDL_WINDOWEVENT)
win = event.window.windowID;
else if ((SDL_EVENTMASK(event.type) & SDL_KEYEVENTMASK) != 0)
win = event.key.windowID;
else if (event.type == SDL_TEXTINPUT)
win = event.text.windowID;
else if (event.type == SDL_MOUSEMOTION)
win = event.motion.windowID;
else if ((SDL_EVENTMASK(event.type) & (SDL_MOUBUTTONDOWNMASK |
SDL_MOUBUTTONUPMASK)) != 0)
win = event.button.windowID;
else if (event.type == SDL_MOUSEWHEEL)
win = event.wheel.windowID;
...
in favor of:
win = event.window.windowID;

The translation incurs a slight overhead for each keyboard event and is therefore disabled by default\&. For each subsequently received key down event, the \fBunicode\fR member of the \fI\fBSDL_keysym\fR\fR structure will then contain the corresponding character code, or zero for keysyms that do not correspond to any character code\&. .PP A value of 1 for \fBenable\fR enables Unicode translation; 0 disables it, and -1 leaves it unchanged (useful for querying the current translation mode)\&. .PP Note that only key press events will be translated, not release events\&. .SH "RETURN VALUE" .PP Returns the previous translation mode (\fB0\fR or \fB1\fR)\&. .SH "SEE ALSO" .PP \fI\fBSDL_keysym\fR\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 22:59
