Re: Route animation in google maps with GWT

Hi Brian,

Thanks for your answer. I tried some things with the array and timer
and that staff. I tried with wait(), sleep() and also with a timer
object. But everytime, there comes an error, that these things are not
supported by gwt..

The easiest way would be to have the normal callback, which gets the
latlng array. Then in the "onSuccess()" Method changing the marker
positions with a for loop and a delay. I tried that, but i couldn't
find a possibility to make this delay

Is it possible to do that like that, or do i have to make already the
callback with the delay? Does that mean, that i have to make two
callbacks, one which gets the array and the secon in a for loop?

Thanks and best regards from switzerland.

Jan
