public class UIPreferencePage
extends FieldEditorPreferencePage
implements IWorkbenchPreferencePage

This class represents a preference page that is contributed to the Preferences dialog. By subclassing { link org.eclipse.jface.preference.FieldEditorPreferencePage}, we can use the field support built into JFace that allows us to create a page that is small and knows how to save, restore and apply itself.

This page is used to modify preferences only. They are stored in the preference store that belongs to the main plug-in class. That way, preferences can be accessed directly via the preference store.
