[Geotools-gt2-users] How do you apply a different style to one shape in a layer?

[Steve B. <me...@bo...>]

Hi,

I'm new to Java and new to GeoTools. I've managed to load a shapefile into a layer and can display it using the StyledMapPane. 
I can alter the colour of all of the polygons in that layer by replacing the layer's style object.
What I want to do is to change the colour of one of the polygons in the layer. 

I have added a field in the shapefile table called "colour" which is an integer which will signify what colour a particular polygon should be drawn in. The problem is I just can't figure out what I need to do to get this to work. 

Could someone please tell me which classes I should be looking at, or point me at some sample code?

Thank you very much,

Regards,

Steve Borg
