Implementing "Get directions" in a gwt application

Question

I need to implement directions using Google maps inside my GWT web application. Currently I'm using maps API v2 library.

I have several issues I have not been able to solve yet:

1. Include Get Directions panel (similar to the Google maps one)
2. Get list of streets names from the request.

PS How to implement mouse wheel zoom control?

Answer 1

I found out how to easily implement zoom functionality:

final MapWidget map = new MapWidget(startLatLng, 12);
map.setSize("100%", "100%");

MapUIOptions options = map.getDefaultUI();
options.setScrollwheel(true);
map.setUI(options);

For more info check out maps demo. You can checkout project code and test it in eclipse!

I'm still searching for solution to other problems.

Answer 2

Here is the answer for your mouse wheel zoom question

Implement HasMouleWheelHandlers and its the API's like getX(), getY(), getScreenX(), getScreenY() and do your zoom operations
