Re: [udig-devel] Get feature on mousePressed method

[Emily Gouge <egouge@xxxxxxxxxxxxxxx>]

A feature source can take a filter so instead of asking for all features 
[source.getFeatures()] you can make a filter and only ask for features 
within that filter [source.getFeatures(myFilter)].

I believe the context associated with your tool should have a 
getBoundingBox(...) function that should return a bounding box around 
where the user clicked.  You can then use a FilterFactory class to 
create a filter.

Have a look at the info tool; it sounds like you are doing something 
similar.
