java - How to pass values of a selected row from tableviewer to a text box in SWT -

i have table has 10 rows, want is: when click button "modify" want pass selected table row values respective textboxes.

i tried codes, not full filling needs,

maintable.addlistener(swt.selection, new listener() {     public void handleevent(event e) {         string string = "";         tableitem[] selection = maintable.getselection();         (int = 0; < selection.length; i++)             string += selection[i] + " ";         final string appname=string.substring(11, string.length()-2);         system.out.println(appname);     } }); 

the above code printing selected row values in console, want set values textboxes.

how can this?

here example code:

private static int        columns = 3; private static list<text> texts   = new arraylist<>();  public static void main(string[] args) {     display display = new display();     final shell shell = new shell(display);     shell.settext("stackoverflow");     shell.setlayout(new gridlayout(columns, false));      table table = new table(shell, swt.full_selection);     table.setlayoutdata(new griddata(swt.fill, swt.fill, true, true, columns, 1));     table.setheadervisible(true);      /* create columns */     (int col = 0; col < columns; col++)     {         new tablecolumn(table, swt.none).settext("col " + col);     }      /* create cells */     (int row = 0; row < 10; row++)     {         tableitem item = new tableitem(table, swt.none);          (int col = 0; col < table.getcolumncount(); col++)         {             item.settext(col, "cell " + row + " " + col);         }     }      /* pack columns */     (int col = 0; col < table.getcolumncount(); col++)     {         table.getcolumn(col).pack();     }      /* create text fields */     (int col = 0; col < columns; col++)     {         text text = new text(shell, swt.border);         texts.add(text);     }      /* listen selection */     table.addlistener(swt.selection, new listener()     {         @override         public void handleevent(event e)         {             table table = (table) e.widget;             tableitem item = table.getitem(table.getselectionindex());              /* fill texts */             (int col = 0; col < table.getcolumncount(); col++)             {                 texts.get(col).settext(item.gettext(col));             }         }     });      shell.pack();     shell.open();      while (!shell.isdisposed())     {         if (!display.readanddispatch())             display.sleep();     }     display.dispose(); } 

looks this:
