Synchroniser les textes de JTextComponents

Voici une petite entité qui permet de synchroniser les textes de plusieurs objets JTextComponent :

gus.graphic.scrollpane.scrollsynchronizer

Code:: package gus05.entity.gus.graphic.textcomp.textsynchronizer; import javax.swing.event.DocumentEvent; import javax.swing.event.DocumentListener; import javax.swing.text.BadLocationException; import javax.swing.text.Document; import javax.swing.text.JTextComponent; import gus05.framework.core.Entity; import gus05.framework.features.Give; public class TextSynchronizer implements Entity, Give { public String getName() {return "gus.graphic.textcomp.textsynchronizer";} public String getCreationDate() {return "2009.11.30";} public void give(Object obj) throws Exception { JTextComponent[] comp = (JTextComponent[]) obj; new SynchText(comp); } private class SynchText implements DocumentListener { private JTextComponent[] comp; private boolean transfering = false; public SynchText(JTextComponent[] comp) { this.comp = comp; for(int i=0;i<comp.length;i++) comp[i].getDocument().addDocumentListener(this); } public void changedUpdate(DocumentEvent e) {} public void insertUpdate(DocumentEvent e) {textChanged(e);} public void removeUpdate(DocumentEvent e) {textChanged(e);} private void textChanged(DocumentEvent e) { if(transfering) return; transfering = true; Document doc = e.getDocument(); transfertFrom(doc); transfering = false; } private void transfertFrom(Document doc) { try { for(int i=0;i<comp.length;i++) { if(comp[i].getDocument()!=doc) comp[i].setText(doc.getText(0,doc.getLength())); } } catch(BadLocationException e){} } } }
