Hand cursor over tile of a TileGrid

Hello,

Based on the showcase example http://www.smartclient.com/smartgwt/showcase/#tiling_basic
could someone point how to get a non-pointer cursor on hover over a tile (Canvas) of a TileGrid?

In general, is there a way to have or control a "hover handler" over a single tile?

Thanks
