Updating textBox value when browser event is fired from javascript

[Mario Barón]

Hey guys,

I have a question, I'm using the javascript approach for GoogleMaps and I'm wondering if there's a way to change the value of a textbox or execute a previously written method from a drag event binded to the map or a marker?

Thanks

Hi,
I have no idea.
Did you notice this: http://www.codenameone.com/3/post/2014/03/mapping-natively.html

Hey Shai,

thanks for your response. I've been trying it out a little today, but I have a question about this. I need to be able to obtain the latitude and longitude from a fixed marker on the center of the map. I need this data to be able to Geocode the info into a valid address using the Google APIs for this. 

With this new native map component, would I be able to listen to a drag event done to the map so I can constantly update and save the coordinates of the marker sitting on the center of it? Can you please indicate me how I would do this? 

Thanks.

You can do this with the JavaScript bridge.  Just register a java callback function then call it from JavaScript.

See the "calling java methods from JavaScript" section on this page:

Hi,
yes there is a map listener API as part of the native component: addMapListener(MapListener)
public interface MapListener {

    public void mapPositionUpdated(Component cmpnt, int i, Coord coord);
}
