Note: The ArcGIS Extension for the Google Maps API and the ArcGIS Extension for Bing Maps have no changes at version 1.5.
In version 1.5 you can change the default mouse cursor behavior and types. The Map already has some built-in cursor changes such as switching to the the four-headed arrow "move" cursor during a pan. You can add other cursor changes by calling Map.setMapCursor() in response to map events. For example, if you made a custom tool for identifying or learning about map features, you might change to the question mark "help" cursor upon activation of the tool. When the user finishes with the tool, you can call setMapCursor again to return to the original cursor.
When you call setMapCursor, you need to supply the cursor type. A list of standard CSS cursor values is available here. Web browsers have built-in support for various cursors, many of which are common to all browsers. Use caution when using cursors that are not supported by all browsers.
