Hey all,

In Java, I want to display the contents of directories on a drive (Windows), like Windows Explorer.

My method to populate the tree works nicely, however, the problem is when it comes across a folder with nothing inside, but is still a folder, it is displayed in the tree as a leaf node, which doesn't have the normal folder symbol.

I could just have all leaf nodes look the same but I don't wish to do this approach, if there is another way that anyone can think of, that would be great.

Thanks!

You can use java.util.Files isDirectory() to determine if something is a directory regardless of the number of children it has. You should use this when determining your CellRenderers.
