Fixed bug #674 Matej 2009-01-08 09:25:34 PST Hello, I maintain a cross-platform project that uses SDL. One of the users who runs OSX has told me that he has problems with linking to SDL due to missing -framework option. I think that the problem is because of this: 'sdl-config --libs' outputs '-L/opt/local/lib -lSDLmain -lSDL -Wl,-framework,Cocoa' All the options are passed to the linker except the last one. I think that the good output should be just: '-L/opt/local/lib -lSDLmain -lSDL -framework Cocoa' since those options (--libs) are passed to the linker, so the '-Wl' option is redundant and possibly harmful in this very case I use autotools with libtool to do the build... Regards, Matej

.SH "DESCRIPTION"
.PP
\fBSDL_JoyBallEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used when an event of type \fBSDL_JOYBALLMOTION\fP is reported\&.
.PP
A \fBSDL_JOYBALLMOTION\fP event occurs when a user moves a trackball on the joystick\&. The field \fBwhich\fR is the index of the joystick that reported the event and \fBball\fR is the index of the trackball (for a more detailed explaination see the \fIJoystick section\fR)\&. Trackballs only return relative motion, this is the change in position on the ball since it was last polled (last cycle of the event loop) and it is stored in \fBxrel\fR and \fByrel\fR\&.
