-/**\r
- * <p>\r
- * Basis of a text components look-and-feel. This provides the basic editor view\r
- * and controller services that may be useful when creating a look-and-feel for\r
- * an extension of <code>JTextComponent</code>.\r
- * <p>\r
- * Most state is held in the associated <code>JTextComponent</code> as bound\r
- * properties, and the UI installs default values for the various properties.\r
- * This default will install something for all of the properties. Typically, a\r
- * LAF implementation will do more however. At a minimum, a LAF would generally\r
- * install key bindings.\r
- * <p>\r
- * This class also provides some concurrency support if the\r
- * <code>Document</code> associated with the JTextComponent is a subclass of\r
- * <code>AbstractDocument</code>. Access to the View (or View hierarchy) is\r
- * serialized between any thread mutating the model and the Swing event thread\r
- * (which is expected to render, do model/view coordinate translation, etc).\r
- * <em>Any access to the root view should first\r
- * acquire a read-lock on the AbstractDocument and release that lock\r
- * in a finally block.</em>\r
- * <p>\r
- * An important method to define is the {@link #getPropertyPrefix} method which\r
- * is used as the basis of the keys used to fetch defaults from the UIManager.\r
- * The string should reflect the type of TextUI (eg. TextField, TextArea, etc)\r
- * without the particular LAF part of the name (eg Metal, Motif, etc).\r
- * <p>\r
- * To build a view of the model, one of the following strategies can be\r
- * employed.\r
- * <ol>\r
- * <li>\r
- * One strategy is to simply redefine the ViewFactory interface in the UI. By\r
- * default, this UI itself acts as the factory for View implementations. This is\r
- * useful for simple factories. To do this reimplement the {@link #create}\r
- * method.\r
- * <li>\r
- * A common strategy for creating more complex types of documents is to have the\r
- * EditorKit implementation return a factory. Since the EditorKit ties all of\r
- * the pieces necessary to maintain a type of document, the factory is typically\r
- * an important part of that and should be produced by the EditorKit\r
- * implementation.\r
- * </ol>\r
- * <p>\r
- * <strong>Warning:</strong> Serialized objects of this class will not be\r
- * compatible with future Swing releases. The current serialization support is\r
- * appropriate for short term storage or RMI between applications running the\r
- * same version of Swing. As of 1.4, support for long term storage of all\r
- * JavaBeans<sup><font size="-2">TM</font></sup> has been added to the\r
- * <code>java.beans</code> package. Please see {@link jsjava.beans.XMLEncoder}.\r

+/**
+ * <p>
+ * Basis of a text components look-and-feel. This provides the basic editor view
+ * and controller services that may be useful when creating a look-and-feel for
+ * an extension of <code>JTextComponent</code>.
+ * <p>
+ * Most state is held in the associated <code>JTextComponent</code> as bound
+ * properties, and the UI installs default values for the various properties.
+ * This default will install something for all of the properties. Typically, a
+ * LAF implementation will do more however. At a minimum, a LAF would generally
+ * install key bindings.
+ * <p>
+ * This class also provides some concurrency support if the
+ * <code>Document</code> associated with the JTextComponent is a subclass of
+ * <code>AbstractDocument</code>. Access to the View (or View hierarchy) is
+ * serialized between any thread mutating the model and the Swing event thread
+ * (which is expected to render, do model/view coordinate translation, etc).
+ * <em>Any access to the root view should first
+ * acquire a read-lock on the AbstractDocument and release that lock
+ * in a finally block.</em>
+ * <p>
+ * An important method to define is the {@link #getPropertyPrefix} method which
+ * is used as the basis of the keys used to fetch defaults from the UIManager.
+ * The string should reflect the type of TextUI (eg. TextField, TextArea, etc)
+ * without the particular LAF part of the name (eg Metal, Motif, etc).
+ * <p>
+ * To build a view of the model, one of the following strategies can be
+ * employed.
+ * <ol>
+ * <li>
+ * One strategy is to simply redefine the ViewFactory interface in the UI. By
+ * default, this UI itself acts as the factory for View implementations. This is
+ * useful for simple factories. To do this reimplement the {@link #create}
+ * method.
+ * <li>
+ * A common strategy for creating more complex types of documents is to have the
+ * EditorKit implementation return a factory. Since the EditorKit ties all of
+ * the pieces necessary to maintain a type of document, the factory is typically
+ * an important part of that and should be produced by the EditorKit
+ * implementation.
+ * </ol>
+ * <p>
+ * <strong>Warning:</strong> Serialized objects of this class will not be
+ * compatible with future Swing releases. The current serialization support is
+ * appropriate for short term storage or RMI between applications running the
+ * same version of Swing. As of 1.4, support for long term storage of all
+ * JavaBeans<sup><font size="-2">TM</font></sup> has been added to the
+ * <code>java.beans</code> package. Please see {@link jsjava.beans.XMLEncoder}.
