Class IconManager

java.lang.Object
  net.sf.japi.swing.IconManager

public final class IconManager
extends Object

Class to handle icons. Default size is 16. Instances must have an associated ClassLoader, otherwise several methods will not work properly but throw a NullPointerException instead. So if you do not provide a ClassLoader, be sure the class you provide has one, or if you use the no-arg constructor resp. the default instance, be sure the IconManager class itself was loaded with some ClassLoader other than null.

Todo:

this class should be refactored into a more generic version and accessible through ActionFactory?, it should be possible to initialize the paths through properties
