zip to JTree

[icsbcn]

Hello,

Anybody know any method to explore a zip file and convert their content to a JTree?

Thank you very much.

You mean represent the contents as a JTree rather than converting the zip file to a JTree, right?
Start by reading the JTree tutorial.

Thank you.

But my problem is how to extract data from a zip file in a format that I can build a JTree or DefaultMutableTreeNode.

You do know How to read Zip files, right?

Yes.

But I can not find solution for my problem.

The builders of a JTree are:

JTree(TreeNode)
JTree(TreeNode, boolean)
JTree(TreeModel)
JTree()
JTree(Hashtable)
JTree(Object[])
JTree(Vector)

But exploring a zip file I'm not able to create any of these structures.

Read the whole of the JTree tutorial that I posted above.

Finally,

I found a possible solution:

public TreeNode generarArbre() {
ZipFile file = null;
try {
file = new ZipFile(ruta);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
System.exit(1);
}
MutableTreeNode arrel = new DefaultMutableTreeNode(nomFitxer);
Map<String,MutableTreeNode> nodes = new HashMap<String,MutableTreeNode>();
nodes.put(nomFitxer, arrel);
for (Enumeration<? extends ZipEntry> e = file.entries(); e.hasMoreElements();) {
ZipEntry entry = e.nextElement();
String name = entry.getName();
MutableTreeNode node = new DefaultMutableTreeNode(name);
nodes.put(name, node);

MutableTreeNode parent = getParent(name, nodes);
parent.insert(node, parent.getChildCount());
}
return arrel;
}

private MutableTreeNode getParent(String name, Map<String,MutableTreeNode> nodes) {
File f = new File(name);
String parent = f.getParent();
// parent == null => parentNode is the root
if (parent == null) {
System.out.println("Nodes:"+nodes.get(nomFitxer));
return nodes.get(nomFitxer);
} else {
parent = parent+File.separator;
}
MutableTreeNode parentNode = nodes.get(parent);
// omitted: null check and creation
return parentNode;
}

Your code contains a smiley inside it!
Better use code tags when posting code tags next time.

So, does it work?

[icsbcn]

I think so.
