[Biojava-l] Highlight Features when clicked? newbie

[Matthew Pocock]

Hi,

One solution is to have 2 top-level renderers. One is painted 'behind' 
the other, and highlights a range. The one in front is your normal 
renderer. Wire the events so that selecting a feature sets the 
highlighting range on the 'behind' renderer.

If you check out the das client code from cvs (it's in a different cvs 
module to biojava-live), you should be able to find some example code 
for this.
