JTree expand problem

Question

Let's say a tree has 3 children, and each children has a hierarchy of subtrees. Is there any way to just expand one children and its subtrees??
root
|_A
|_SUBTREE
|_B
|_SUBTREE
|_C
|_SUBTREE
If I do the following, it will expand the whole big tree.
JTree tree;
//etc...
1) /** Expand the tree */
for (int i=0; i<tree.getRowCount(); i++)
tree.expandRow(i);
If I do this, it own expands the first 6 children (including the subtrees of each children)
2) /** Expand the tree */
for (int i=0; i<6; i++)
tree.expandRow(i);
any ideas?? please help!!

Answer 1

I think u mistook my point. Let's say a JTree has 3 children as follows:
and each child has its own tree hierarchy.
root
|_SUBTREE1
|_SUBTREE2
|_SUBTREE3
All I want is when the user click a particular tree node, the whole subtree will expand.
I tried the following, but it only expands the child of the tree node I selected.
public void treeExpanded(TreeExpansionEvent evt)
{     System.out.println("treeExpanded...");
          TreePath path = evt.getPath();
          int pathCount = path.getPathCount();
          System.out.println(pathCount);
for (int i=0; i<pathCount; i++)
tree.expandPath(path);
Any ideas???
