Demo Code


//package com.java2s;

import javax.swing.text.Document;

public class Main {
    private static final Object TYPING_MODIFICATION_DOCUMENT_PROPERTY = new Object();

    /**/*from   w w  w . j  a  v  a  2  s . co m*/
     * Mark that the ongoing document modification(s) will be caused
     * by user's typing.
     * It should be used by default-key-typed-action and the actions
     * for backspace and delete keys.
     * <br/>
     * The document listeners being fired may
     * query it by using {@link #isTypingModification(Document)}.
     * This method should always be used in the following pattern:
     * <pre>
     * DocumentUtilities.setTypingModification(doc, true);
     * try {
     *     doc.insertString(offset, typedText, null);
     * } finally {
     *    DocumentUtilities.setTypingModification(doc, false);
     * }
     * </pre>
     *
     * @see #isTypingModification(Document)

        doc.putProperty(TYPING_MODIFICATION_DOCUMENT_PROPERTY,
                Boolean.valueOf(typingModification));
    }
