    Để xóa các biểu tượng thì :
    Mã:
    [B]DefaultTreeCellRenderer renderer2 = new DefaultTreeCellRenderer();[/B]
[B] renderer2.setOpenIcon(null);[/B]
[B] renderer2.setClosedIcon(null);[/B]
[B] renderer2.setLeafIcon(null);[/B]
[I]tree[/I][B].setCellRenderer(renderer2);[/B]
    Hay tham khảo tại mục 5 ở đây.
