API資料大全

 This event is sent to observers that have implemented the 
 <A HREF="../../../javax/swing/event/DocumentListener.html"><CODE>DocumentListener</CODE></A>
 interface and registered interest with the model being observed.

 <p>
 <dt><b><font size=+1>Location Information</font></b>
 <dd>
 The capability of determining the location of text in
 the view is provided.  There are two methods, <A HREF="../../../javax/swing/text/JTextComponent.html#modelToView(int)"><CODE>modelToView(int)</CODE></A>
 and <A HREF="../../../javax/swing/text/JTextComponent.html#viewToModel(java.awt.Point)"><CODE>viewToModel(java.awt.Point)</CODE></A> for determining this information.

 <p>
 <dt><b><font size=+1>Undo/Redo support</font></b>
 <dd>
 Support for an edit history mechanism is provided to allow
 undo/redo operations.  The text component does not itself
 provide the history buffer by default, but does provide
 the UndoableEdit records that can be used in conjunction
 with a history buffer to provide the undo/redo support.
 The support is provided by the Document model, which allows
 one to attach UndoableEditListener implementations.

 <p>
 <dt><b><font size=+1>Thread Safety</font></b>
 <dd>
 The swing text components provide some support of thread
 safe operations.  Because of the high level of configurability
 of the text components, it is possible to circumvent the
 protection provided.  The protection primarily comes from
 the model, so the documentation of AbstractDocument
 describes the assumptions of the protection provided.
 The methods that are safe to call asynchronously are marked
 with comments.
 </dl>

 <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.  A future release of Swing will provide support for
 long term persistence.
