make-tree example only has root

I am not sure what the make-tree example is supposed to do, but all I get is the single root item:

The "test" items don't appear.

You're right, I'm seeing the same behavior. Please run fltkhs-tree-simple for a better demonstration of the tree widget. The corresponding source is in src/Examples/tree-simple.hs.

Thanks for the bug report!
