I would have thought that draggable markers would be a better place to
start than the overview. This is very similar identical to a draggable marker
except it doesn't pan/follow the map.
Well, I guess both approaches could work, but markers (or vector features) is
rather closely tided to moving with the map, and you then would have to
override a lot of that behaviour..

Hi All,
I have a unique requirement that I need help with.
Perhaps this is something new...
Well, the fact that you need this does not mean that anyone
here is entiteled to make it for you..
The best way to describe it is to look at this:
http://www.youtube.com/watch?v=sXotq-W5HmA&feature=channel but the gunsight is
not always in the center, you can drag it around in the map viewport.
So,
+ I need a Gunsight control (which uses
Map.getLonLatFromPixel() to work out the geographical focus of where the gun is
pointing).
+ The Gunsight does not move when the map is
panned/moved (it's tied to pixel position - not geographical)
+ The Gunsight needs to be draggable within the map
view port <div> (can't drag outside the viewport) a non-draggable/fixed pixel
position solution (i.e. center of map viewport) would be an unacceptable.
I think a good starting point could be looking at the
OverviewMap control, which uses a div placed on top of the map, and then make a
control yourself based on somewhat the same concept.
Good luck!
Thanks && Cheers :)
