TreeTabel and file download

Hello list,

I'm trying to implement small file browser and I use TreeTable. 
PropertyTreeColumn shows file names and I can get (newCell -> 
getTreeTable().getTreeState().isNodeSelected(node)) java.io.File. Now, 
I'm need force to download file after click on the file name. Any 
suggestions?

Thanks,

Anton

I solved it.

                 new PropertyTreeColumn(new 
ColumnLocation(Alignment.MIDDLE, 8, Unit.PROPORTIONAL),
                         "", "userObject.name") {
                     @Override
                     public IRenderable newCell(TreeNode node, int level)
                     {
                         if 
(getTreeTable().getTreeState().isNodeSelected(node)) {
                             File f = new PropertyModel<File>(node, 
"userObject.file").getObject();
                             ResourceStreamRequestTarget res = new 
ResourceStreamRequestTarget(
                                 new FileResourceStream(f), f.getName());
                             getRequestCycle().setRequestTarget(res);
                             return null;
                         } else {
                             return super.newCell(node, level);
                         }
                     }
                 }

and

TreeTable tree = new TreeTable("treeTable", createTreeModel(), columns);
tree.setLinkType(TreeTable.LinkType.REGULAR);

Hello Martin,

thanks for your reply! You mean override newLink method in 
DefaultAbstractTree?
