Why JTRee icon did not display?

Hello sir:

I can use a panel to display JTree's all nodes and their icons independently in a independent JtreeIcon.java;

but when I put this JTree into another panel, I can see only tree's all nodes and their text strings, but cannot see their icons, if I use Drag and Drop to move these nodes, the icon moved displays its icon, other ones still not display their icon,

I think I am short of some methiods, can any guru advice?

Thanks
