Re: [OpenMap Users] Mouse Wheel events

One use that occurred to me would be to use the wheel in my ZoomMouseMode
to zoom the map in and out. Scrolling the map up and down would work too
but panning wouldn't. Why didn't they go the whole hog and put a ball on
top of the mouse too then we'd be able to "wheel" sideways too! Also those
of us who are upside down in the southern hemisphere would be able to turn
our mice upside down too and have them work properly.

It's well known that Coriolis force in the southern hemisphere goes "the
other way" and we have to have CRTs that compensate for the different
electron flight path. What's not so well known is that it also affects the
trajectory of the mouse pointer but it's the user has to compensate.
Northern hemisphere people tend to home in on the target with a trajectory
that starts off high of the target and curves left down on to it. Southern
hemisphere people tend to do the opposite way - come up on things from
below :-) You'd think that, by now, Microsoft would have done something
about it. Why not have a mouse driver which has prediction algorithms
built in and figures where you are heading and jumps there. They could
probably re-use the code for targeting incoming ICBMs too.

regards,

Adrian

I hadn't though about it. What would you have them do? I guess that
doesn't matter, infrastructure-wise. You would use them like you want.

I would agree.

Well, I was trying to keep OpenMap's java requirement at 1.2, but at
the last minute some error handling code slipped in there that required
1.4, which is why the OpenMap 4.6 java requirement jumped to 1.4. So,
since we're already under that requirement, we should just go all out,
what the heck. There's some I/O stuff that would be really good to
incorporate to speed up data file input.

If anyone can think of a reason to hold off on pushing the requirement
squarely to jdk 1.4, please let me know.

- Don
