[geotk] mouse click event on shape

[sorel johann]

Hello

If you are using the JMap2D that's fast.

//make a search area based on your mouse position
Shape searchArea = new 
Rectangle(mouse.getPoint().x-2,mouse.getPoint().y-2,4,4);
//each time something hit the search area it will be passed to the visitor
GraphicVisitor visitor = new ...(your own visitor);
//make the search
map.getCanvas().getGraphicsIn(searchArea, visitor, VisitFilter.INTERSECTS);


If you are using a mapcontext object, don't forget that maplayers should 
be set selectable
otherwise the visite method won't return results for the layer.
