I guess you never got my DirectInput dlm to work? Is my code that bad?
:( I've done all of this for you... You never did say what platform
you are on and maybe that is the problem. It should work for Win2k/XP
with DirectX 9. What version of IDL?

Thank you very much!
Now I got the answer,and I've made a nice effect of what I wanted.
Let's cheers!!^_^
ps:I've found another bug of IDL.I don't know whether you have met it
before.
Let's see this code:
IF (event.x LT 1) OR (event.x GT drawX-1) THEN BEGIN
TVCRS,0,0,/Device
ENDIF
When I move the mouse slowly or steady to the edge of the
Widget_Draw,the IDL can access the position of the mouse,and made the
right action that set the mouse to the [0,0],but If I move the mouse
very fast to the edge of the Window,it seemed that the IDL can't catch
the change of the mouse ,then the mouse moved to the outside of the
window ,rather than made the action that set the mouse to the [0,0].
You can test this,of course,this is not a big problem,we can use many
ways to avoid them,but it indeed exists.

Yes, this definitely needs to be packaged in something for re-use.

Seems to me the effect you are looking for isn't so much having the
"mouse offset" represent the "radian that "head" need to rotate", but
rather have the offset proportional to the rate of change of the
"head" turn.
By making the offset porportional to the rate of turn rather than the
absolute magnitude having the mouse cursor centered would keep the
viewing angle steady (no turn). Having it mouse at the left window
edge would have the view turning to the left at a maximum allowable
rate. Having the mouse partially to the left of center would turn the
"head" left at a slower rate. That would allow continuous rotation to
the left(right) whenever the mouse is to the left(right) of center.
I haven't played any first person angle games in quite a while, but
that is how I remember them working.
Being able to re-center the mouse, as Mike's pro above does would
still be useful to quickly stop any rotation.
Bob.

Well, now, there is an idea! I would package this up in
a new window object, though, so the object could keep
track of all the manipulations, resizings, etc. Then
you could just create a MoveCursorTo method.

How about this trick: put a direct graphics window (of the same size)
behind the object graphics window.
Check out:
http://michaelgalloy.com/wp-content/uploads/2007/07/cursor_t est.pro
and let me know if that is the effect your are looking for. Push any
ASCII key or the button on the bottom to move the cursor to the given
location (x: 200, y: 100).

Thank you again,David.
I don't know wheather you have been played the first person angle
games like Quake3 or Counter Strike.In this games ,we can use the
mouse to control the rotating of the "head",we can move the mouse to
the left represent the "head" rotating to the left even if move the
mouse to the side of the screen it still can be useful.I recorded the
start position and end position of the mouse moving,use the offset
representing the radian that "head" need to rotate.But when I move the
cursor to the side of the screen,I have no idea how to make a
continuous rotating of the "head",because I can't use the offset of
the cursor movement to represent the radian that "head" rotating in
this situation.So I think if this situation happened,I can set the
mouse to the center or the other side of the screen,then I can make a
continuous one direction mouse moving which is representing the
continuous rotating of the "head".In fact,there must be some other way
to realize this effect.Like DirectX and OpenGL all have their own
function to realize this effect.But I'm highly wished we can use the
IDL to realize it.
Hope I've interpreted it clearly.Please parden my poor english.That is
also a hard work for me too.^_*
Thanks!

Unfortunately, I think the answer is "not much." I spent
the better part of a half hour this afternoon fooling
around with this, and I couldn't come up with a thing.
From the deafening silence, I'm afraid others are striking
out, too.
It probably goes against some GUI principle to allow
anyone other than the user to control the mouse, but
I guess I could think of one or two reasons why you
might have legitimate reason to want to do so. In any
case, unless I've missed something, I don't think it is
possible in object graphics. (Of course, you could put
an arrow or something inside a graphics windows and move
THAT around, but that isn't the cursor.)
Cheers,
David
