The new version of Google Maps GWT API is available for download :
  • All classes now have real constructors, no more create methods..
  • Removed some of the GMap2Widget constructors
  • Implemented GPolygon
  • In hosted mode the GMap2Widget.getMaps() function will check to see if the Goolge Maps java script is in your HTML and will now give an error message in the GWT Log if it is missing.
