- * 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 JTextComponent.
- *
- * Most state is held in the associated JTextComponent 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.
- *
- * This class also provides some concurrency support if the
- * Document associated with the JTextComponent is a subclass of
- * AbstractDocument. 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).
- * Any access to the root view should first
- * acquire a read-lock on the AbstractDocument and release that lock
- * in a finally block.
- *
- * 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). - *
- * To build a view of the model, one of the following strategies can be - * employed. - *
- * Warning: 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
- * JavaBeansTM has been added to the
- * java.beans package. Please see {@link jsjava.beans.XMLEncoder}.

+/**
+ *
+ * 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 JTextComponent.
+ *
+ * Most state is held in the associated JTextComponent 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.
+ *
+ * This class also provides some concurrency support if the
+ * Document associated with the JTextComponent is a subclass of
+ * AbstractDocument. 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).
+ * Any access to the root view should first
+ * acquire a read-lock on the AbstractDocument and release that lock
+ * in a finally block.
+ *
+ * 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). + *
+ * To build a view of the model, one of the following strategies can be + * employed. + *
+ * Warning: 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
+ * JavaBeansTM has been added to the
+ * java.beans package. Please see {@link jsjava.beans.XMLEncoder}.
