The tricky part is what happens if the user tries to expand a subdirectory which doesn't happen to contain any subdirectories. Just like the Windoze explorer (cough) directory view, I want the expander for that directory to "magically" disappear when the user tries to expand it.
Use gtktreestore model. Add a dummy for non expanded directories. That makes the expander appear. When the user expands, if nothing is in there, collapse the node and remove the dummy. Since there will be no children, the expander disappears.
Hmm.. Yeah - that should work I guess. Although it feels a bit backward from an object-oriented point-of-view.
But what would you do if some other process or whatever creates a file in that directory? You will not be able to expand it, unless you are constantly monitoring the contents.
The view is transient so I don't think that would be a real problem. But I could easily add some kind of (user activated) refresh mechanism if that would be necessary. If I store the last modified timestamp along with the directory name, it would just be a matter of checking whether the timestamp has changed.
