[OpenLayers-Users] mouse event return clicked layer

[gustavo palminha]

Hi to all.

After reinventing half the wheel in order to provide a way for manifold to
use a sort of getfeatureinfo, the following tool was built, see the link for
preview  http://img180.imageshack.us/img180/7664/manifoldgetfeatureinfo.jpg
http://img180.imageshack.us/img180/7664/manifoldgetfeatureinfo.jpg  .

The next enhancements for this manifold getfeatureinfo will be:
>> Provide a sort of precision parameter for the right mouse click. 
>> Provide a sort of multi manifold wms url access.

As said the main goal was after a right map click, a ballon would be
launched with the information content as seen above so it's working now.

Regards.
