Re: Using native methods in a JavascriptObject class

Why are you try to get this from native javascript.

Try to implement this, using gwt objects.

You can insert gwt-map js from the normal view, not from EntryPoint.
Here code example:

public MapRootView() {
Maps.loadMapsApi("", "2", false, new Runnable() {

@Override
public void run() {
isApiLoaded = true;
}

});
}

Next method will be called only when this view will be requested.
@Override
public void createView() {
initWidget(uiBinder.createAndBindUi(this));
// TODO add some perfect loading stub
// timer is used because of asynchronous library loaded
Timer apiLoadedTimer = new Timer() {

@Override
public void run() {
// when api loaded just create and add map to the page.
if (isApiLoaded) {
createMapWidget();
mapHolder.setSize("100%", "300px"); // this is very important
that height must be specified (parent div)
mapHolder.add(mapWidget);

cancel();
}
}

};

apiLoadedTimer.scheduleRepeating(1000);

}

For now, you can do whatever you want, because you have mapWidget,
LatLong objects, etc.

private void createMapWidget() {
LatLng kievCity = LatLng.newInstance(50, 30); // Kiev city (I hope,
sarcasm) will be the center
mapWidget = new MapWidget(kievCity, 12); // initialize a widget
mapWidget.setSize("100%", "100%"); // set size for map
mapWidget.addControl(new LargeMapControl()); // add a control for
map
mapWidget.getBounds(); // return you a bounds of currently showing
picture
}

Don't forget about timer - google-map-js loads asynchronously.
