public void registerAction(java.lang.String s,
                           NiteAction a)

Description copied from class: JComponentHandler

This is used to register an action listener for the action; well, in fact it's overridden by every class that extends this, so it's not really!

Overrides:

registerAction in class JComponentHandler

displayElement

public javax.swing.JComponent displayElement(ObjectModelElement e,
                                             boolean selected)

Description copied from interface: OutputComponent
