/**
 * Demonstrates three different styles when to commit changes:
 * on key typed, on focus lost, on OK/Apply pressed.
 * Therefore we bind 3 JTextFields to 3 String typed ValueModels
 * that honor the commit style. And we bind 3 JLabels directly 
 * to these ValueModels that display the current value.<p>
 * 
 * The ValueModels used in this example are requested from a
 * PresentationModel that adapts text properties of a TextBean.
 * This is just to demonstrate a consistent binding style.
 * The same techniques work with any ValueModel.
