Collapse a node in a JTree?

[Andreas Wachhold]

Hello,

I want to collapse a node from a JTree down its children. I have found
a nice method that expands a node down its children, but I am stuck at
collapsing. Here is the expand thing:

---
//expand a single node
private static void expandSingleNode(
JTree tree,
TreeModel data,
TreePath path) {

Object node = path.getLastPathComponent();
int count = data.getChildCount(node);

//System.out.println(node);

if (count == 0) {
if (data.isLeaf(node))
tree.expandPath(path.getParentPath());
else
tree.expandPath(path);
} else
for (int i = 0; i < count; i++)
expandSingleNode(
tree,
data,
path.pathByAddingChild(data.getChild(node, i)));
}

Can you help me?

Reading the JTree API documentation would have helped you much quicker.
Or is there anything wrong with collapsPath()?

BTW, beginner's questions should best go to comp.lang.java.help. Real
GUI questions to comp.lang.java.gui.
