```
public class WGoogleMap
extends WCompositeWidget
```
A widget that displays a google map.
This widget uses the online Google Maps server to display a map. It exposes a part of the google maps API.
This widget supports both version 2 and version 3 of the Google Maps API. The version 2 API is used by default, to enable the version 3 API, use the constructor's version argument.
To use the map on a public server you will need to obtain a key. The widget will look for this key as the configuration property "google_api_key". If this configuration property has not been set, it will use a key that is suitable for localhost.

  - render
```
protected void render(java.util.EnumSet<RenderFlag> flags)
```
    Description copied from class: WWidget
    
    Renders the widget.
    This function renders the widget (or an update for the widget), after this has been scheduled using scheduleRender().
    The default implementation will render the widget by serializing changes to JavaScript and HTML. You may want to reimplement this widget if you have been postponing some of the layout / rendering implementation until the latest moment possible. In that case you should make sure you call the base implementation however.
    
    Overrides:
    
    render in class WCompositeWidget
  - doGmJavaScript
```
protected void doGmJavaScript(java.lang.String jscode)
```
    Execute a piece of JavaScript that manipulates the map.
    This is like WCompositeWidget#doJavaScript() but delays the javascript until the map has been loaded.
