Hi,
I have been playing with the drawing tools 
example<http://gmaps-samples-v3.googlecode.com/svn/trunk/drawing/drawing-tools.html>and
 found it very well designed, neat, capable and functional. However, I 
think the current design MAY, to some extent, limit it to client side and 
geometry based apps, rather than client/server and business based apps 
(although we could provide customised marker, which is good but not 
enough).  

 

I have put some thoughts in order to expand the applicable fields (could be 
wrong but hope to put my purpose across, or let me know if any of them is 
already achievable):

 

1.    have an accessible id field for each overlay, either managed by map or 
user, so that the developer could easily distinguish between each overlay. This 
would be useful, for example, if we want to correlate an overlay on map screen 
and its copy in the backend database when editing.

2.    Expose the functions which are called when we click the drawing 
icons/buttons on map (MARKER, POLYLINE, RECTANGLE, CIRCLE, POLYGON), so that 
developer could also call them through other means, e.g. via menu items if they 
wish, without using icons/buttons on map.

3.    Provide customisation for map icon/buttons, i.e. images and titles (shown 
when mouseover), so that we could use “business” based map buttons, rather than 
“geometry” based map buttons (e.g. “Plant a tree” vs. “Add a marker”).

 

Make sense?
