Hi,

Im just looking at GClientGeocoder in order to do a reverse geocode.
I've used geocoder.getLocations(GLatLng) to begin a search.  At this
point I also provide the user with a 'cancel' link to prevent the user
waiting if the information is not forthcoming.

But I can't see how I can stop the callback being called if the user
clicks 'cancel'.

I tried geocoder.reset() - but that didn't work!!

I guess I'll see if the cancel link is still visible or not - but
surely there is a better way??

Any ideas?

Many thanks

Ben

Once you've issued the request, you can't stop the response (if there
is one).  You can choose to ignore it though - modify your callback
routine to test some condition that is set or unset by the cancel
button.

Your users would have to be pretty fast to manage to hit the cancel
button before the GClientGeocoder timeout. If the server hasn't
responded in half a second, the client gives up and returns
G_GEO_SERVER_ERROR.
