Subject: SDL: Relative mouse movements
The patch below will reenable processing of relative mouse movements.
The DirectFB drivers generates those in "grabbed" mode. These ensure,
that even in fullscreen mode relative movements are reported. SDLMAME
depends on this for games with trackballs.
Looking at the code I ask myself whether relative movements should be
handled in the drivers (x11, directfb). Both x11 and directfb are able
to report relative movements. This would leave it to the driver to use
the most appropriate method for relative movements when at the border of
a fullscreen window or being "grabbed".

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
