java - Refresh/Update highlighter in JTable when changing search values -

how can refresh highlighter in jtable after changing search value in jtextfield? works fine jtextarea under jtextfield, jtable won't refresh highlighter. suggestions??

this code:

import java.awt.*; import java.awt.event.*;  import javax.swing.*; import javax.swing.table.*; import javax.swing.text.*; import javax.swing.text.defaulthighlighter.defaulthighlightpainter;  public class beispieltabelle { jtextfield field; jtextarea textfeld = new jtextarea("hello world!"); string input="stefan";  //titel der tabelle string[] title = {"eins", "zwei", "drei"};   //tabellendaten object[][] playerdata = {        {"34", "stefan", "mein name ist stefan"}, {"32", "dirk", "ich bin der dirk"}, {"99", "patrick", "ich heisse patrick"}, {"100", "anna", "ich bin die anna"},};  //tablemodel defaulttablemodel model = new defaulttablemodel(playerdata,title);  //tabelle erstellen jtable texttable = new jtable(model);      public jpanel erstelletabelle() {                    jpanel totalgui = new jpanel();         //cellrenderer     searchrenderer cellrenderer = new searchrenderer();       //spaltenbreiten festlegen     texttable.setdefaultrenderer(string.class, cellrenderer);     texttable.getcolumnmodel().getcolumn(0).setcellrenderer(cellrenderer);     texttable.getcolumnmodel().getcolumn(1).setcellrenderer(cellrenderer);         texttable.getcolumnmodel().getcolumn(2).setcellrenderer(cellrenderer);      texttable.setautoresizemode(jtable.auto_resize_off); // autoresizing abschalten, sonst sind alle spalten gleich breit:     texttable.getcolumnmodel().getcolumn(0).setpreferredwidth(60);     texttable.getcolumnmodel().getcolumn(1).setpreferredwidth(60);     texttable.getcolumnmodel().getcolumn(2).setpreferredwidth(180);             //das ganze scrollbar machen     jscrollpane scrollpane = new jscrollpane(texttable);      //textfeld erstellen     field = new jtextfield();     field.addactionlistener(new actionlistener () {         @override         public void actionperformed(actionevent e) {             input = field.gettext();             system.out.println(input);             //updaterowheights();             highlighttext();         }     });              totalgui.add(scrollpane);       totalgui.add(field);     totalgui.add(textfeld);             return totalgui; }  void highlighttext() {     defaulthighlightpainter yellowpainter = new defaulthighlighter.defaulthighlightpainter(color.yellow);     highlighter highlighter = textfeld.gethighlighter();     highlighter.removeallhighlights();           string text = textfeld.gettext();     string pattern = input;     int index = text.indexof(pattern);           while ( index >= 0 ) {         int len = pattern.length();         try {             highlighter.addhighlight(index, index+len, yellowpainter);         } catch (badlocationexception e) {             e.printstacktrace();         }         index = text.indexof(pattern, index+len);     } }  private static void createandshowgui() {      //create main frame     jframe mainframe = new jframe("");     beispieltabelle test = new beispieltabelle();      jpanel totalgui = new jpanel();     totalgui = test.erstelletabelle();     totalgui.setlayout(new boxlayout(totalgui, boxlayout.y_axis));      //visible mode     mainframe.setdefaultcloseoperation(jframe.exit_on_close);     mainframe.add(totalgui); //integrate main panel main frame     mainframe.pack();     mainframe.setvisible(true);      }   public static void main (string[] args) {                     createandshowgui();       }//main }//gui_main 

and searchrenderer

import javax.swing.*; import javax.swing.table.*; import javax.swing.text.badlocationexception;  import java.awt.*;  public class searchrenderer extends jtextarea implements tablecellrenderer {  /**  *   */ private static final long serialversionuid = 1l; public searchrenderer() {}//constructor beispieltabelle tabelle = new beispieltabelle(); string textforsearch=tabelle.input;  @override public component gettablecellrenderercomponent (jtable table,                                                 object value,                                                 boolean isselected,                                                 boolean hasfocus,                                                 int row,                                                                     int column ) {       this.settext((string) value);     if(value != null) {         string string = value.tostring();         if(string.contains(textforsearch)){             int indexof = string.indexof(textforsearch);             while(indexof >=0) {             try {                       this.gethighlighter().addhighlight(indexof,indexof+textforsearch.length(),new javax.swing.text.defaulthighlighter.defaulthighlightpainter(color.green));             } catch (badlocationexception e) {                 e.printstacktrace();             }             indexof = string.indexof(textforsearch, indexof+textforsearch.length());         }     }     } else {         this.settext("");         this.gethighlighter().removeallhighlights();     }     return this; } } 

maybe can use jtable#repaint()
